Agriculture Residues Recycling  

E-Print Network (OSTI)

Abstract: Saudi Arabia, as well as other countries in the Near East region, is characterized by erratic weather conditions, limited area of fertile arable lands, and with acute water shortage. Although agricultural residues (AGR) production in the region is huge (more than 440 million tons), most of these residues are either burned in the field or utilized in an inefficient way. Utilization of AGR as compost may contribute to expansion of arable lands through its use for reclamation of soil and reduce irrigation requirements. This study was conducted at Al Khalidiah farm, Riyadh, Saudi Arabia to assess compost production at large commercial scale using several types of agricultural and animal by-products with addition of a BZT®Compost Activator (based mainly on microorganism, enzymes and yeast). In this study, two types of compost piles were made at the farm. The first pile of compost was made of different agriculture residues, namely: animal wastes (quail, goat and sheep manure), brownian agricultural wastes (windbreaks residues, date trees, citrus and olive trees pruning) and green landscape grasses (50%, 25 % and 25%, respectively) and was treated with a tested compost activator. The same agriculture residues combination was also made for the second pile as traditional compost

Composition and utilization of cellulose for chemicals from agricultural residues  

DOE Green Energy (OSTI)

This study was undertaken for several reasons. Firstly, because of the scarcity of data on the composition of certain agricultural residues generated predominantly in California, it could only be inferred from the published composition of agricultural grains and wood what the carbohydrate composition of the residue straw, stems, and roots might be. Published methods of analysis on wood and grains were adapted or modified to suit these materials, resulting in an analytical system applicable to these residues. Secondly, a series of chemical pretreatments were studied to see if sugar production by enzymatic hydrolysis might be improved. Also these studies are used as a basis of generating the data for chemical engineering parameters of the Berkeley process. Since lignin is ultimately used as a feed back energy source in the Berkeley process, it is not necessary for it to be in the form of a relatively low weight polymer. Therefore, a study on the use of recoverable chemical solvents for dilignification by solution, rather than by a depolymerization reaction is indicated.

Modeling Sustainable Agricultural Residue Removal at the Subfield Scale  

Science Conference Proceedings (OSTI)

This study developed a computational strategy that utilizes data inputs from multiple spatial scales to investigate how variability within individual fields can impact sustainable residue removal for bioenergy production. Sustainable use of agricultural residues for bioenergy production requires consideration of the important role that residues play in limiting soil erosion and maintaining soil C, health, and productivity. Increased availability of subfield-scale data sets such as grain yield data, high-fidelity digital elevation models, and soil characteristic data provides an opportunity to investigate the impacts of subfield-scale variability on sustainable agricultural residue removal. Using three representative fields in Iowa, this study contrasted the results of current NRCS conservation management planning analysis with subfield-scale analysis for rake-and-bale removal of agricultural residue. The results of the comparison show that the field-average assumptions used in NRCS conservation management planning may lead to unsustainable residue removal decisions for significant portions of some fields. This highlights the need for additional research on subfield-scale sustainable agricultural residue removal including the development of real-time variable removal technologies for agricultural residue.

Logging and Agricultural Residue Supply Curves for the Pacific Northwest  

DOE Green Energy (OSTI)

This report quantified the volume of logging residues at the county level for current timber harvests. The cost of recovering logging residues was determined for skidding, yearding, loading, chipping and transporting the residues. Supply curves were developed for ten candidate conversion sites in the Pacific Northwest Region. Agricultural field residues were also quantified at the county level using five-year average crop yields. Agronomic constraints were applied to arrive at the volumes available for energy use. Collection costs and transportation costs were determined and supply curves generated for thirteen candidate conversion sites.

Cost Methodology for Biomass Feedstocks: Herbaceous Crops and Agricultural Residues  

DOE Green Energy (OSTI)

This report describes a set of procedures and assumptions used to estimate production and logistics costs of bioenergy feedstocks from herbaceous crops and agricultural residues. The engineering-economic analysis discussed here is based on methodologies developed by the American Society of Agricultural and Biological Engineers (ASABE) and the American Agricultural Economics Association (AAEA). An engineering-economic analysis approach was chosen due to lack of historical cost data for bioenergy feedstocks. Instead, costs are calculated using assumptions for equipment performance, input prices, and yield data derived from equipment manufacturers, research literature, and/or standards. Cost estimates account for fixed and variable costs. Several examples of this costing methodology used to estimate feedstock logistics costs are included at the end of this report.

Microbiological Production of Surfactant from Agricultural Residuals for IOR Application  

SciTech Connect

Utilization of surfactants for improved oil recovery (IOR) is an accepted technique with high potential. However, technology application is frequently limited by cost. Biosurfactants (surface-active molecules produced by microorganisms) are not widely utilized in the petroleum industry due to high production costs associated with use of expensive substrates and inefficient product recovery methods. The economics of biosurfactant production could be significantly impacted through use of media optimization and application of inexpensive carbon substrates such as agricultural process residuals. Utilization of biosurfactants produced from agricultural residuals may 1) result in an economic advantage for surfactant production and technology application, and 2) convert a substantial agricultural waste stream to a value-added product for IOR. A biosurfactant with high potential for use is surfactin, a lipopeptide biosurfactant, produced by Bacillus subtilis. Reported here is the production and potential IOR utilization of surfactin produced by Bacillus subtilis (American Type Culture Collection (ATCC) 21332) from starch-based media. Production of surfactants from microbiological growth media based on simple sugars, chemically pure starch medium, simulated liquid and solid potato-process effluent media, a commercially prepared potato starch in mineral salts, and process effluent from a potato processor is discussed. Additionally, the effect of chemical and physical pretreatments on starchy feedstocks is discussed.

Wood Residues as Fuel Source for Lime Kilns  

E-Print Network (OSTI)

One of the main obstacles to total energy self sufficiency of kraft mills appears to be the fossil fuel requirements of the lime kilns. If an economical technology can be developed which allows fossil fuel to be replaced in whole or in part by wood-based fuel, the savings in fossil fuel by the pulp and paper industry would be very substantial. Our study focuses around the direct in-situ combustion of hog fuel fed from the cold feed end in order to substantially reduce the fossil fuel fired from the hot product discharge end of the lime kiln. Thus far we have carried out two series of tests using two different pilot-scale kilns and dry limestone in the first test series and mill produced lime mud in the second test series. Mill scale trials have just been completed and the preliminary results indicate that our approach is potentially a very cost-effective and simple option to substantially reduce or possibly eliminate fossil-fuel usage in lime kilns.

Sustainable agricultural residue removal for bioenergy: A spatially comprehensive US national assessment  

SciTech Connect

This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States for bioenergy production. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included the number of environmental factors, the number of land management scenarios, and the spatial fidelity and spatial extent of the assessment. This study utilizes integrated multi-factor environmental process modeling and high fidelity land use datasets to perform the sustainable agricultural residue removal assessment. Soil type represents the base spatial unit for this study and is modeled using a national soil survey database at the 10–100 m scale. Current crop rotation practices are identified by processing land cover data available from the USDA National Agricultural Statistics Service Cropland Data Layer database. Land management and residue removal scenarios are identified for each unique crop rotation and crop management zone. Estimates of county averages and state totals of sustainably available agricultural residues are provided. The results of the assessment show that in 2011 over 150 million metric tons of agricultural residues could have been sustainably removed across the United States. Projecting crop yields and land management practices to 2030, the assessment determines that over 207 million metric tons of agricultural residues will be able to be sustainably removed for bioenergy production at that time. This biomass resource has the potential for producing over 68 billion liters of cellulosic biofuels.

Honey Lake hybrid geothermal wood residue power plant, Lassen County, California  

DOE Green Energy (OSTI)

The feasibility of a proposed 50 MW (gross) electric power project located near Wendel, California about 25 miles east of Susanville was studied. The project would be the first commercial power plant to combine the use of geothermal energy and wood fuel for power production. Wood fuel consisting primarily of various forms of forest management residues would be processed and partially dehydrated with geothermal energy prior to combustion. Geothermal energy would also be used for boiler feedwater heating and combustion air preheating. The study defines the range of site-specific benefits and economics of using wood fuel and moderate temperature geothermal energy, both of which are abundant and often located in proximity at many locations in the western United States. The study results document conclusively that overall project economics can be very favorable and that in addition to providing an important source of electric power, many benefits to forest land managers, local communities, project developers and the state of the environment can be derived from the combined use of moderate temperature geothermal energy and wood fuel.

A Multi-Factor Analysis of Sustainable Agricultural Residue Removal Potential  

Science Conference Proceedings (OSTI)

Agricultural residues have significant potential as a near term source of cellulosic biomass for bioenergy production, but sustainable removal of agricultural residues requires consideration of the critical roles that residues play in the agronomic system. Previous work has developed an integrated model to evaluate sustainable agricultural residue removal potential considering soil erosion, soil organic carbon, greenhouse gas emission, and long-term yield impacts of residue removal practices. The integrated model couples the environmental process models WEPS, RUSLE2, SCI, and DAYCENT. This study uses the integrated model to investigate the impact of interval removal practices in Boone County, Iowa, US. Residue removal of 4.5 Mg/ha was performed annually, bi-annually, and tri-annually and were compared to no residue removal. The study is performed at the soil type scale using a national soil survey database assuming a continuous corn rotation with reduced tillage. Results are aggregated across soil types to provide county level estimates of soil organic carbon changes and individual soil type soil organic matter content if interval residue removal were implemented. Results show interval residue removal is possible while improving soil organic matter. Implementation of interval removal practices provide greater increases in soil organic matter while still providing substantial residue for bioenergy production.

Co-combustion of textile residues with cardboard and waste wood in a packed bed  

SciTech Connect

The combustible fraction of the municipal waste is mostly bio-derived. Energy recovery of the wastes that cannot be economically recycled is a key part of sustainable energy policy and waste management. Textile residues have high energy content. When burned alone in a packed bed system, however, their combustion efficiency is low due to the irregular propagation of the ignition front and the low burning rates. In order to achieve more efficient combustion of textile residues, a series of co-combustion tests were carried out for various mixture compositions and air flow rates in a packed bed combustor. The combustion performance of these materials was evaluated by using quantitative measures such as ignition rate, burning rate and equivalence ratio. Co-combustion of textile residues with cardboard for a textile fraction of up to 30% achieved satisfactorily high burning rate and low unburned carbon content in the bottom ash. The mixture was more resistant to convective cooling by air, which significantly expanded the range of air flow rate for combustion at high burning rates. In co-combustion with a material that has a very low ignition front speed such as waste wood, the propagation of the ignition front was governed by textile residues. Therefore, the co-combustion of textile residues can be better performed with a material having similar ignition front speeds, in which the two materials simultaneously burn at the ignition front.

Black-Right-Pointing-Pointer Prediction of the syngas heating value. Black-Right-Pointing-Pointer Investigation of the temperature effect in reduction zone in syngas concentration. - Abstract: A non-stoichiometric model for a downdraft gasifier was developed in order to simulate the overall gasification process. Mass and energy balances of the gasifier were calculated and the composition of produced syngas was predicted. The capacity of the modeled gasifier was assumed to be 0.5 MW, with an Equivalence Ratio (EQ) of 0.45. The model incorporates the chemical reactions and species involved, while it starts by selecting all species containing C, H, and O, or any other dominant elements. Olive wood, miscanthus and cardoon were tested in the formulated model for a temperature range of 800-1200 Degree-Sign C, in order to examine the syngas composition and the moisture impact on the supplied fuel. Model results were then used in order to design an olive wood gasification reactor.

Feasibility study for anaerobic digestion of agricultural crop residues. Dynatech report No. 1935  

DOE Green Energy (OSTI)

The objective of this study was to provide cost estimates for the pretreatment/digestion of crop residues to fuel gas. A review of agricultural statistics indicated that the crop residues wheat straw, corn stover, and rice straw are available in sufficient quantity to provide meaningful supplies of gas. Engineering economic analyses were performed for digestion of wheat straw, corn stover, and rice straw for small farm-, cooperative-, and industrial scales. The small farm scale processed the residue from an average size US farm (400 acres), and the other sizes were two and three orders of magnitude greater. The results of the analyses indicate that the production of fuel gas from these residues is, at best, economically marginal, unless a credit can be obtained for digester effluent. The use of pretreatment can double the fuel gas output but will not be economically justifiable unless low chemical requirements or low cost chemicals can be utilized. Additional development is necessary in this area. Use of low cost hole-in-the-ground batch digestion results in improved economics for the small farm size digestion system, but not for the cooperative and industrial size systems. Recommendations arising from this study are continued development of autohydrolysis and chemical pretreatment of agricultural crop residues to improve fuel gas yields in an economically feasible manner; development of a low cost controlled landfill batch digestion process for small farm applications; and determination of crop residue digestion by-product values for fertilizer and refeed.

Potential use of wood and agriculture wastes as steam generator fuel for thermal enhanced oil recovery. Final report  

DOE Green Energy (OSTI)

Enhanced oil recovery by steam injection methods produces over 200,000 barrels per day of crude oil in California. A sizeable portion of the produced crude, up to 40% for some projects, may be burned to generate steam for injection into the reservoir. The purpose of this study is to evaluate the potential to use wood and agriculture wastes to replace crude oil as steam generator fuel. The Bakersfield area of California's San Joaquin Valley is the focus for this paper. Production from thermal EOR methods centers around Bakersfield and agriculture and wood wastes are available from the San Joaquin Valley and the nearby Sierra Nevada mountains. This paper documents the production of waste materials by county, estimated energy value of each material, and estimated transportation cost for each material. Both agriculture and wood wastes were found to be available in sizeable quantities and could become attractive steam generation fuels. However, some qualifications need to be made on the use of these materials. Transportation costs will probably limit the range of shipping these materials to perhaps 50 to 100 miles. Availability is subject to competition from existing and developing uses of these materials, such as energy sources in their immediate production area. Existing steam generators probably cannot be retrofitted to burn these materials. Fluidized bed combustion, or low Btu gasification, may be a good technology for utilization. FBC or FBG could accept a variety of waste materials. This will be important because the amount of any single waste may not be large enough to support the energy requirements of a good size thermal f a good size thermal EOR operation.

Anaerobic fermentation of agricultural residue: potential for improvement and implementation. Final report  

DOE Green Energy (OSTI)

The results of studies designed to evaluate the potential of rapidly improving the technology of anaerobic fermentation of agricultural residues and methods of implementing it in existing agricultural operations are reported. The main objectives of this study were to: identify simple and low cost anaerobic fermentor design criteria that would be appropriate in small agricultural operations, develop high rate fermentor concepts that would enable multiple product recovery from the reactor, expand the information base particularly in the area of temperature influence on the process, and to review sociological and economic issues relating to implementation of fermentation technology. This study has identified several major anaerobic fermentation concepts which illustrate that the technology may be rapidly improved. A simple reactor design utilizing an unmixed plug flow concept was shown to be comparable to the more complex completely mixed reactor when using dairy cow residue. A high rate thermophilic reactor designed to encourage flotation of particulate solids illustrated that liquid, solid, and gaseous products can be generated within the anaerobic fermentor thus eliminating an additional dewatering unit process. A third reactor concept involved extension of the anaerobic attached microbial film expanded bed to the treatment of cow manure slurries. A high rate of methane generation was recorded. Comprehensive thermophilic fermentation studies (60/sup 0/C) indicated that the increased temperature resulted in little improvement in total quantity or the rate of yield of gas over that obtained with mesophilic fermentation with reactor retention periods greater than 10 days. Finally, other areas where preliminary date were obtained are noted.

Using a Decision Support System to Optimize Production of Agricultural Crop Residue Biofeedstock  

Science Conference Proceedings (OSTI)

For several years the Idaho National Laboratory (INL) has been developing a Decision Support System for Agriculture (DSS4Ag) which determines the economically optimum recipe of various fertilizers to apply at each site in a field to produce a crop, based on the existing soil fertility at each site, as well as historic production information and current prices of fertilizers and the forecast market price of the crop at harvest, for growing a crop such as wheat, potatoes, corn, or cotton. In support of the growing interest in agricultural crop residues as a bioenergy feedstock, we have extended the capability of the DSS4Ag to develop a variable-rate fertilizer recipe for the simultaneous economically optimum production of both grain and straw, and have been conducting field research to test this new DSS4Ag. In this paper we report the results of two years of field research testing and enhancing the DSS4Ag’s ability to economically optimize the fertilization for the simultaneous production of both grain and its straw, where the straw is an agricultural crop residue that can be used as a biofeedstock.

Developing an Integrated Model Framework for the Assessment of Sustainable Agricultural Residue Removal Limits for Bioenergy Systems  

DOE Green Energy (OSTI)

Agricultural residues have significant potential as a feedstock for bioenergy production, but removing these residues can have negative impacts on soil health. Models and datasets that can support decisions about sustainable agricultural residue removal are available; however, no tools currently exist capable of simultaneously addressing all environmental factors that can limit availability of residue. The VE-Suite model integration framework has been used to couple a set of environmental process models to support agricultural residue removal decisions. The RUSLE2, WEPS, and Soil Conditioning Index models have been integrated. A disparate set of databases providing the soils, climate, and management practice data required to run these models have also been integrated. The integrated system has been demonstrated for two example cases. First, an assessment using high spatial fidelity crop yield data has been run for a single farm. This analysis shows the significant variance in sustainably accessible residue across a single farm and crop year. A second example is an aggregate assessment of agricultural residues available in the state of Iowa. This implementation of the integrated systems model demonstrates the capability to run a vast range of scenarios required to represent a large geographic region.

Review: Balancing Limiting Factors and Economic Drivers to Achieve Sustainable Midwestern US Agricultural Residue Feedstock Supplies  

Science Conference Proceedings (OSTI)

Advanced biofuels will be developed using cellulosic feedstock rather than grain or oilseed crops that can also be used for food and feed. To be sustainable, these new agronomic production systems must be economically viable without degrading soil resources. This review examines six agronomic factors that collectively define many of the limits and opportunities for harvesting crop residue for biofuel feedstock. These six “limiting factors” are discussed in relationship to economic drivers associated with harvesting corn (Zea mays L.) stover as a potential cellulosic feedstock. The limiting factors include soil organic carbon, wind and water erosion, plant nutrient balance, soil water and temperature dynamics, soil compaction, and off-site environmental impacts. Initial evaluations using the Revised Universal Soil Loss Equation 2.0 (RUSLE2) show that a single factor analysis based on simply meeting tolerable soil loss might indicate stover could be harvested sustainably, but the same analysis based on maintaining soil organic carbon shows the practice to be non-sustainable. Modifying agricultural management to include either annual or perennial cover crops is shown to meet both soil erosion and soil carbon requirements. The importance of achieving high yields and planning in a holistic manner at the landscape scale are also shown to be crucial for balancing limitations and drivers associated with renewable bioenergy production.

Chemical and microbiological hazards associated with recycling of anaerobic digested residue intended for agricultural use  

Science Conference Proceedings (OSTI)

In the present study, three full-scale biogas plants (BGP) were investigated for the concentration of heavy metals, organic pollutants, pesticides and the pathogenic bacteria Bacillus cereus and Escherichia coli in the anaerobically digested residues (ADR). The BGPs mainly utilize source-separated organic wastes and industrial food waste as energy sources and separate the ADR into an ADR-liquid and an ADR-solid fraction by centrifugation at the BGP. According to the Norwegian standard for organic fertilizers, the ADR were classified as quality 1 mainly because of high zinc (132-422 mg kg{sup -1} DM) and copper (23-93 mg kg{sup -1} DM) concentrations, but also because of high cadmium (0.21-0.60 mg kg{sup -1} DM) concentrations in the liquid-ADR. In the screening of organic pollutants, only DEHP (9.7-62.1 mg kg{sup -1}) and {Sigma} PAH 16 (0.2-1.98 mg kg{sup -1} DM) were detected in high concentrations according to international regulations. Of the 250 pesticides analyzed, 11 were detected, but only imazalil (<0.30-5.77 mg kg{sup -1} DM) and thiabendazol (<0.14-0.73 mg kg{sup -1} DM) were frequently detected in the ADR-fiber. Concentrations of imazalil and thiabendazol were highest during the winter months, due to a high consumption of citrus fruits in Norway in this period. Ten percent of the ADR-liquid samples contained cereulide-producing B. cereus, whereas no verotoxigenic E. coli was detected. The authors conclude that the risk of chemical and bacterial contamination of the food chain or the environment from agricultural use of ADR seems low.

Environmental and economic evaluation of energy recovery from agricultural and forestry residues  

DOE Green Energy (OSTI)

Four conversion methods and five residues are examined in this report, which describes six model systems: hydrolysis of corn residues, pyrolysis of corn residues, combustion of cotton-ginning residues, pyrolysis of wheat residues, fermentation of molasses, and combustion of pulp and papermill wastes. Estimates of material and energy flows for those systems are given per 10/sup 12/ Btu of recovered energy. Regional effects are incorporated by addressing the regionalized production of the residues. A national scope cannot be provided for every residue considered because of the biological and physical constraints of crop production. Thus, regionalization of the model systems to the primary production region for the crop from which the residue is obtained has been undertaken. The associated environmental consequences of residue utilization are then assessed for the production region. In addition, the environmental impacts of operating the model systems are examined by quantifying the residuals generated and the land, water, and material requirements per 10/sup 12/ Btu of energy generated. On the basis of estimates found in the literature, capital, operating, and maintenance cost estimates are given for the model systems. These data are also computed on the basis of 10/sup 12/ Btu of energy recovered. The cost, residual, material, land, and water data were then organized into a format acceptable for input into the SEAS data management program. The study indicates that the most serious environmental impacts arise from residue removal rather than from conversion.

Anaerobic fermentation of agricultural residues: potential for improvement and implementation. Seventh quarter progress report, December 16, 1977--March 15, 1978  

DOE Green Energy (OSTI)

This is the seventh progress report of an on-going three year research effort to contribute to the development of a new and/or improved technology that will result in wide spread use of an anaerobic fermentation in agriculture to generate a renewable clean energy source. Activities are now concentrating on full-scale and pilot-scale demonstration of simplified fermentors for manures. Activities for the seventh quarter year, extending from December 16, 1977 to March 15, 1978, have included the following: completion of construction of the full scale conventional control fermenter; completion of construction, testing and startup of the random mix fermenter; installation of feed and effluent lines, electrical wiring, boilers, gas lines and controls; successful testing of the ram pump; conclusion of the 35/sup 0/C studies with the pilot scale plug flow fermenter and the initiation of the low temperature (25/sup 0/C) studies; and preparation of a detailed outline to the design manual. As of March 15, 1978, the overall progress achieved with the major components of the project was estimated to be about 2.5 months behind the work plan schedule. As detailed in the last progress report, much of this delay has been due to the winter weather (i.e., cold temperatures, snow, frozen ground, etc.) which has interfered with excavation and other outdoor construction activities.

An analysis of producing ethanol and electric power from woody residues and agricultural crops in East Texas  

E-Print Network (OSTI)

The increasing U.S. dependence on imported oil; the contribution of fossil fuels to the greenhouse gas emissions and the climate change issue; the current level of energy prices and other environmental concerns have increased world interest in renewable energy sources. Biomass is a large, diverse, readily exploitable resource. This dissertation examines the biomass potential in Eastern Texas by examining a 44 county region. This examination considers the potential establishment of a 100-megawatt (MW) power plant and a 20 million gallon per year (MMGY) ethanol plant using lignocellulosic biomass. The biomass sources considered are switchgrass, sugarcane bagasse, and logging residues. In the case of electricity generation, co-firing scenarios are also investigated. The research analyzes the key indicators involved with economic costs and benefits, environmental and social impacts. The bioenergy production possibilities considered here were biofeedstock supported electric power and cellulosic ethanol production. The results were integrated into a comprehensive set of information that addresses the effects of biomass energy development in the region. The analysis indicates that none of the counties in East Texas have sufficient biomass to individually sustain either a 100% biomass fired power plant or the cellulosic ethanol plant. Such plants would only be feasible at the regional level. Co-firing biomass with coal, however, does provide a most attractive alternative for the study region. The results indicate further that basing the decision solely on economics of feedstock availability and costs would suggest that bioenergy, as a renewable energy, is not a viable energy alternative. Accounting for some environmental and social benefits accruing to the region from bioenergy production together with the feedstock economics, however, suggests that government subsidies, up to the amount of accruing benefits, could make the bioenergies an attractive business opportunity for local farmers and investors.

Silviculture: growing more wood on less land  

SciTech Connect

Maximizing the production of a concentrated, homogeneous wood supply virtually dictates intensively managed plantations. This management system implies: (1) improving the composite genotype of plantation trees; (2) optimizing their morphological and physiological condition prior to and at planting time; (3) improving the physiological environment of the crop at all stages of development; (4) protecting the plantation from pests and catastrophic events; and (5) modifying the shapes, dimensions, and qualities of crop trees to enhance the utility and value of harvested timber. Beneficiation of forest residuals for fiber and fuel is pushing forest industry relentlessly toward total stand utilization. Relative to the productivity of undisturbed or partially logged humid tropical forests, plantation growth rates represent four-fold to ten-fold increases in volume production. Displacement of some proportion of shifting agriculture and natural forest management systems by intensively managed plantations is desirable and biologically feasible. A key to successful tropical forest management and preservation is population stability, a condition toward which integrated wood conversion facilities supplied by a reliable plantation system can make a major contribution. There are some pressing and many esoteric reasons for conserving forest resources but pressures for utilizing and renewing these resources are immediate and unavoidable.

Potential of biomass residue availability; The case of Thailand  

SciTech Connect

An acute shortage of fuel wood and charcoal prevails in many developing countries. A logical approach to the problem places emphasis on the development of alternative energy sources, including use of biomass residues. An assessment of the potential of biomass residues for energy and other uses calls for an estimation of their annual production. Also, because the residues are normally bulky they should be utilized near their place of origin whenever possible to avoid high transportation costs. Thus knowledge of the total national generation of residues per year does not provide enough information for planning residue utilization. This article illustrates a method of residue estimation that takes the case of Thailand as an example. It presents the annual generation of nine agricultural resides (paddy husk, paddy straw, bagasse, cotton stalk, corn cob, groundnut shell, cassava stalk and coconut husk and shell) and one forestry residue (sawdust) in different agroeconomic zones and regions of Thailand. The methodology used for the investigation of crop-to-residue ratios is outlined. The annual generation figures for the different residues along with observations about their traditional uses are presented.

This study systematically examined the current and future wood pellet market, estimated the cost of Canadian torrefied pellets, and compared the torrefied pellets with the conventional pellets based on literature and industrial data. The results showed that the wood pellet industry has been gaining significant momentum due to the European bioenergy incentives and the rising oil and natural gas prices. With the new bioenergy incentives in USA, the future pellets market may shift to North America, and Canada can potentially become the largest pellet production centre, supported by the abundant wood residues and mountain pine beetle (MPB) infested trees.

Techno-economic analysis of wood biomass boilers for the greenhouse industry  

SciTech Connect

The objective of this study is to perform a techno-economic analysis on a typical wood pellet and wood residue boiler for generation of heat to an average-sized greenhouse in British Columbia. The variables analyzed included greenhouse size and structure, boiler efficiency, fuel types, and source of carbon dioxide (CO2) for crop fertilization. The net present value (NPV) show that installing a wood pellet or a wood residue boiler to provide 40% of the annual heat demand is more economical than using a natural gas boiler to provide all the heat at a discount rate of 10%. For an assumed lifespan of 25 years, a wood pellet boiler system could generate NPV of C$259,311 without electrostatic precipitator (ESP) and C$74,695 with ESP, respectively. While, installing a wood residue boiler with or without an ESP could provide NPV of C$919,922 or C$1,104,538, respectively. Using a wood biomass boiler could also eliminate over 3000 tonne CO2 equivalents of greenhouse gases annually. Wood biomass combustion generates more particulate matters than natural gas combustion. However, an advanced emission control system could significantly reduce particulate matters emission from wood biomass combustion which would bring the particulate emission to a relatively similar level as for natural gas.

Wood, bark, and the wax-coated seeds from Chinese tallow tree (Sapium sebiferum (L.) Roxb. syn. Triadica sebifera (L.) Small), an invasive tree species in the southeastern United States, were subjected to extractions and degradative chemical analyses in an effort to better understand the mechanism(s) by which this tree species aggressively competes against native vegetation, and also to facilitate utilization efforts. Analysis of the wood extractives by FTIR spectroscopy showed functionalities analogous to those in hydrolyzable tannins, which appeared to be abundant in the bark; as expected, the seeds had a high wax/oil content (43.1%). Compared to other fast-growing hardwoods, the holocellulose content for the Chinese tallow tree wood was somewhat higher (83.3%). The alpha-cellulose (48.3%) and Klason lignin (20.3%) contents were found to be similar to those for most native North American hardwoods. Results suggest that Chinese tallow tree wood utilization along with commercial wood species should not present any significant processing problems related to the extractives or cell-wall chemistry. Keywords: Cellulose, Chinese tallow tree, extractives, Klason lignin, utilization.

Economics of modifying harvesting systems to recover energy wood  

SciTech Connect

Recent interest in the recovery of previously underutilized logging residues for energy has stimulated the development of a variety of technologies for bringing this resource to market. The most promising approach for the independent contractor working the south eastern United States is to incorporate residue recovery equipment into his existing harvesting system. Computer simulation was used to assess the potential impact of adding small chippers or residue balers to three common harvesting systems. The systems are used in pine plantations, and mixed pine hardwood and upland hardwood stands. Changes in both operating costs and capital used were used to measure the effect of moving from conventional products to total energy wood harvests and capturing residues for energy in conjunction with conventional products. Incremental analysis was used to assess the operating cost per ton and capitalization per ton of annual production associated with the addition of the residue recovery capability. In nearly every case the incremental cost per ton and the incremental capitalization per ton associated with adding capability (for recovering wood residues for energy) to conventional harvesting systems were considerably less than for establishing systems of the same configuration (to produce energy wood only). The flow of conventional products must not be interrupted by the residue recovery process. Clearcutting or thinning operations conducted primarily for the production of enery wood did not appear to be economical on any stand, given 1979 residue values, unless a proportion of the large diameter trees are merchandized as conventional products. This statement, of course, must take into account that the cost used for both conventional products and the full tree chips were based upon 1979 pulp chip prices. If the alternative value of this material as fuel rises above its current value for fiber, this situation may change.

The Wood Duck

Wood Duck Wood Duck Nature Bulletin No. 502-A October 13, 1973 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation THE WOOD DUCK Of all the fowl that swim, the Wood Duck is a most unusual bird. They perch in trees like jaybirds, and nest in tree holes like woodpeckers. The hens do not quack like the females of most ducks, and the drakes are dressed in a riot of gaudy colors. Each summer we see dozens of them -- more than any other kind of wild duck -- rear their families of ducklings on and around the streams, ponds, lakes and sloughs of Cook County's forest preserves. Words can scarcely describe the brilliance of the drake's plumage. The head, crest and back glint with iridescent greens, purples and blues. The eyes are red, the throat white, and the bill orange-red. The breast is wine-colored flecked with white, the belly is white, and the sides are buff. The woodie is about midway in size between the mallard and the blue-winged teal. The drakes weigh about a pound and a half. The hen is smaller and plainer, with a gray-brown head and body, a white throat, and a conspicuous white ring around the eye. Her voice is a shrill, squealing "whoo-eek", while the male's is a mere squeak.

Weathering and Protection of Wood  

E-Print Network (OSTI)

Introduction When wood is exposed outdoors, above ground, a complex combination of chemical, mechanical, and light energy factors contribute to what is described as weathering (38). Weathering is not to be confused with decay, which results from decay organisms (fungi) acting in the presence of excess moisture and air for an extended period of time (34). Under conditions suitable for the development of decay, wood can deteriorate rapidly and the result is far different than that observed for natural outdoor weathering, Outdoor Weathering Process In outdoor weathering of smooth wood, original surfaces become rough as grain raises and the wood checks, and the checks grow into large cracks; grain may loosen, boards cup and warp and pull away from fasteners (Figs. 1 and 2), The roughened surface changes color, gathers dirt and mildew, and may become unsightly; the wood loses its surface coherence and becomes friable, splinters, and frag ments come off.

Wood and energy in connecticut. Staff report  

SciTech Connect

Telephone surveys of Connecticut households conducted in 1979 indicate a transition to wood heating in response to a series of conventional energy price increases and uncertainty in conventional energy supplies. Connecticut households consumed 668,000 cords of wood in the winter of 1978-79. The airtight wood stove has become the most commonly used wood-burning apparatus. Survey data of residential wood cutting, purchasing, and burning were analyzed by household tenure, wood-burning apparatus, and county. Residential use of wood for energy constitutes a new demand on the forest resource, increases local income and employment, displaces fuel oil and electricity, but may compromise household safety.

Characterization of Waste Tar Associated with Abandoned Wood Chemical Plant Sites in Northwest Pennsylvania, USA  

SciTech Connect

Over 70 wood chemical plants operated in northern Pennsylvania between ca. 1890 and 1950, all located within 72 km of the New York state border. Their original purpose was to salvage the small unwanted hardwood trees left behind by the lumber mills, and to make charcoal, calcium acetate and methanol for a number of industrial uses via destructive distillation. At many old wood chemical plant sites, unknown quantities of wood tar remain as a residual contaminant and pose a pollution threat to aquatic life in nearby streams. Research on the composition and properties of residual wood tars from five abandoned industrial sites in Pennsylvania are described. Weathered wood tars were more viscous and contained fewer volatile and semivolatile organic compounds than did soil-buried tars. Phenol, 2-methylphenol (o-cresol), 4-methylphenol (p-cresol), and 2, 4-dimethylphenol were found in all sampled tars. These water-soluble phenolic compounds were released quasi-instantaneously in aqueous solution, followed by a slower rate of release, consistent with the behavior of similar compounds in other dense non-aqueous liquids. Air-exposed wood tar deposits developed a hard crust, which contained fewer volatiles and semivolatiles and had a higher softening point than other samples. These tars eroded to form a powdered soil colonized by lichens and mosses. Residual wood tar material found at one site was shown to be thermally altered, likely during the historical destruction of the chemical plant by fire. Recovered wood tar wastes have a relatively high heating value and may have use as a potential, but limited, alternate energy source.

Anaerobic fermentation of agricultural residues: potential for improvement and implementation. Twelfth quarter progress report, 16 March 1979-15 June 1979 and Addendum describing project activities, 16 June 1979-15 October 1979  

DOE Green Energy (OSTI)

Five different types of anaerobic fermentor reactor designs were operated, with the majority of effort focused on two full scale reactors (both about 35m/sup 3/), each designed to process the manure residues from up to 65 dairy cows. Three pilot units (5m/sup 3/ volume) are being operated to determine the limits of operation variables - temperature, labor inputs, mixing, and bedding composition. The low-cost full scale plug flow reactor has now been operated for more than one year, including the winter with the lowest temperature for the longest period recorded for the northern New York area. During the twelfth quarter the full scale plug flow and conventional control reactors were tested in parallel at new conditions of 15 days and 10 days HRT, 35/sup 0/C and 10 to 12% TS manure feed. Steady state results for the 15 day HRT condition once more indicated a more efficient solids conversion with the plug flow design (34.1% TVS destruction efficiency) than with the completely mixed full scale system (27.8% TVS destruction efficiency) when operated on dairy manure (13% TS) at 35/sup 0/C. No serious operational problems have been encountered with either full scale reactor during the twelfth quarter. Thermal data from the plug flow reactor has now been obtained for a full year cycle. The apparent overall efficiency of the boiler and reactor heating systems varied between 40 and 55%. In order to translate the temperature and operating data of the plug flow unit into a comprehensible energy balance, a computer model for the prediction of energy production and for the description of conducted heat losses and feed heating requirements was developed. Data analysis and the development of certain sections of the final report were given considerable attention throughout the twelfth quarter. The preparation of the farmer's feasibility manual was also initiated during this period.

Agriculture, technology, and conflict  

E-Print Network (OSTI)

Conflict and agriculture have a long, shared history. The purpose of this research is to look at the relationships between agriculture, agricultural technologies, and conflict during current and recent conflicts, large scale and localized. Agriculture and its related technologies are often affected by conflict, but rarely acknowledged as a cause or solution to conflict. Literature reviews in six topic areas illustrate various facets of the relationship between agriculture and conflict. Research conducted in Santa Cruz del Quiché, Guatemala illustrates the ways farmers were impacted by the country’s civil war. It also examines farmer survival strategies during the war, and reveals the presence of minor localized conflict over water resources. Conflict over land is not a major concern at present. Market access for inputs and outputs are shown to have been a problem for a number of farmers during the civil war. The poverty of Santa Cruz farmers indicates that much could be gained by rural development. Research is unable to support the hypotheses that agricultural technologies have prevented or caused conflict in Santa Cruz del Quiché, or that they have played a large role in recovery from the country’s civil war. The author recommends that future research be undertaken in regions with a diverse set of agricultural technologies, and/or a recent history of significant technological change in agriculture. Policy recommendations include providing secure access to markets during war time, increasing capacity for home-based rural production, and continuing research into resilient crops. Finally, the author suggests that the responsible decision to develop, adopt, or introduce an agricultural technology must take into account the social consequences of that decision, including how the new technology may alleviate or contribute to conflict.

Minnesota wood energy scale-up project 1994 establishment cost data  

DOE Green Energy (OSTI)

The Minnesota Wood Energy Scale-up Project began in late 1993 with the first trees planted in the spring of 1994. The purpose of the project is to track and monitor economic costs of planting, maintaining and monitoring larger scale commercial plantings. For 15 years, smaller scale research plantings of hybrid poplar have been used to screen for promising, high-yielding poplar clones. In this project 1000 acres of hybrid poplar trees were planted on Conservation Reserve Program (CRP) land near Alexandria, Minnesota in 1994. The fourteen landowners involved re-contracted with the CRP for five-year extensions of their existing 10-year contracts. These extended contracts will expire in 2001, when the plantings are 7 years old. The end use for the trees planted in the Minnesota Wood Energy Scale-up Project is undetermined. They will belong to the owner of the land on which they are planted. There are no current contracts in place for the wood these trees are projected to supply. The structure of the wood industry in the Minnesota has changed drastically over the past 5 years. Stumpage values for fiber have risen to more than $20 per cord in some areas raising the possibility that these trees could be used for fiber rather than energy. Several legislative mandates have forced the State of Minnesota to pursue renewable energy including biomass energy. These mandates, a potential need for an additional 1700 MW of power by 2008 by Northern States Power, and agricultural policies will all affect development of energy markets for wood produced much like agricultural crops. There has been a tremendous amount of local and international interest in the project. Contractual negotiations between area landowners, the CRP, a local Resource Conservation and Development District, the Minnesota Department of Natural Resources and others are currently underway for additional planting of 1000 acres in spring 1995.

Textile Drying Via Wood Gasification  

E-Print Network (OSTI)

This project was carried out to investigate the possibility of using wood gas as a direct replacement for natural gas in textile drying. The Georgia Tech updraft gasifier was used for the experimental program. During preliminary tests, the 1 million Btu/hr pilot plant produced clean burning gas which appeared viable for drying textiles. The gasifier was coupled to a modified textile drying oven and a series of tests were carried out to assess product degradation of white, colored, and chemically treated fabrics.

Agriculture and Foods Agriculture and Foods Nature Bulletin No. 387-A September 19, 1970 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation INDIAN AGRICULTURE AND FOODS Most of the Indian tribes east of the Great Plains were part-time farmers. Some of them cultivated sunflowers, giant ragweed, canary grass and pigweed for their seeds, which they used as food. Many grew tobacco. But corn, beans and squash -- wherever the climate permitted - - were the principal crops. There were several varieties of beans. They ate both the seeds and rinds of some dozens of kinds of squash and pumpkin. When game was not abundant there was a wealth of wild fruits, berries, and many kinds of wild plants with edible leaves, seeds, or roots. Corn, however, was the ' staff of life" and they depended on corn, beans and squash -- "the three sisters" -- for year-round food.

Treatment of Wood Preserving Wastewater  

E-Print Network (OSTI)

The wastewater produced by the wood preserving industry presents a difficult problem to treat economically. A review of the literature indicates the size of the industry has limited the pursuit of an orderly and economic solution. Atmospheric evaporation was one possible means of treatment which had not been studied to any great degree. Two bench scale evaporation units were employed to determine the fundamental relationships affecting wastewater quality during such treatment. In batch evaporation tests, it was repeatedly demonstrated that a constant rate of total organic carbon and chemical oxygen demand removal occurred as the wastewater was evaporated. A procedure for designing atmospheric evaporation ponds was developed and applied to a hypothetical wood preserving plant. From this example design estimates of equivalent hydrocarbon concentrations in the air downwind of the pond are made. Various other design considerations such as the input data, modifications to the design procedure, solids accumulation, and miscellaneous design aspects are discussed. A treatment scheme incorporating atmospheric evaporation ponds after chemical coagulation and settling is proposed.

Alaska Wood Biomass Energy Project Final Report  

SciTech Connect

The purpose of the Craig Wood Fired Boiler Project is to use waste wood from local sawmilling operations to provide heat to local public buildings, in an effort to reduce the cost of operating those buildings, and put to productive use a byproduct from the wood milling process that otherwise presents an expense to local mills. The scope of the project included the acquisition of a wood boiler and the delivery systems to feed wood fuel to it, the construction of a building to house the boiler and delivery systems, and connection of the boiler facility to three buildings that will benefit from heat generated by the boiler: the Craig Aquatic Center, the Craig Elementary School, and the Craig Middle School buildings.

Wastes and by-products - alternatives for agricultural use  

Science Conference Proceedings (OSTI)

Top address a growing national problem with generation of wastes and by-products, TVA has been involved for several years with developing and commercializing environmentally responsible practices for eliminating, minimizing, or utilizing various wastes/by-products. In many cases, reducing waste generation is impractical, but the wastes/by-products can be converted into other environmentally sound products. In some instances, conversion of safe, value-added agricultural products in the best or only practical alternative. TVA is currently involved with a diversity of projects converting wastes/by-products into safe, economical, and agriculturally beneficial products. Environmental improvement projects have involved poultry litter, cellulosic wastes, used battery acid, ammonium sulfate fines, lead smelting effluents, deep-welled sulfuric acid/ammonium bisulfate solutions, wood ash, waste magnesium ammonium sulfate slurry from recording tape production, and ammunition plant waste sodium nitrate/ammonium nitrate streams.

Solvolytic liquefaction of wood under mild conditions  

DOE Green Energy (OSTI)

Conversion of wood to liquid products requires cleavage of bonds which crosslink the wood structure. This study examines a low-severity wood solubilization process utilizing a solvent medium consisting of a small amount of sulfuric acid and a potentially wood-derivable alcohol. In one half hour of reaction time at 250/sup 0/C under 15 psia starting nitrogen pressure, over 95% of the wood (maf) was rendered acetone-soluble. The product is a soft, black, bitumen-like solid at room temperature but readily softens at 140/sup 0/C. Between 25 and 50% of the original wood oxygen, depending on alcohol used, was removed as water. Approximately 2 to 17% of the alcohols were retained in the product. Gel permeation chromatography showed that the product's median molecular weight is around 300. Based on experimental and literature results, a mechanism for wood solubilization is proposed. This involves protonation of the etheric oxygen atoms, leading to subsequent bond scission to form carbonium ions which are stabilized by solvent alkoxylation. At severe conditions, polymerization and condensation reactions result in acetone-insoluble materials.

Synthesis of SiC nanorods from bleached wood pulp  

DOE Green Energy (OSTI)

Unbleached and bleached soft wood pulps have been used as templates and carbon precursors to produce SiC nanorods. Hydrolyzed tetraethylorthosilicate (TEOS), Silicic acid was infiltrated into the pulps followed by a carbothermal reduction to form SiC nanorods at 1400oC in Ar. Residual carbon formed along with SiC was removed by gasification at 700oC in air. The SiC materials prepared from unbleached pulp were non-uniform SiC with a thick SiO2 coating, while the SiC nanorods prepared from the bleached pulp were uniform and straight with dimensions of 250 nm in diameter and 5.0 mm long. The formation of uniform camelback structure of SiC in the reaction between silica and bleached pulp is attributed to more silica deposited in the amorphous region of cellulose.

Fusion-fission reactions with modified Woods-Saxon potential  

E-Print Network (OSTI)

A modified Woods-Saxon potential model is proposed for a unified description of the entrance channel fusion barrier and the fission barrier of fusion-fission reactions based on the Skyrme energy-density functional approach. The fusion excitation functions of 120 reactions have been systematically studied. The fusion (capture) cross sections are well described with the calculated potential and an empirical barrier distribution. Incorporating a statistical model (HIVAP code) for describing the decay of the compound nucleus, the evaporation residue (and fission) cross sections of 51 fusion-fission reactions have been systematically investigated. Optimal values of some key parameters of the HIVAP code are obtained based on the experimental data of these reactions. The experimental data are reasonably well reproduced by the calculated results. The upper and lower confidence limits of the systematic errors of the calculated results are given.

The report evaluates the potential impact of USDA Forest Service wood utilization and wood energy research on rural employment and income. Recent projections suggest employment will decrease in many forest products industries, such as softwood sawmilling, but will eventually increase in softwood plywood and reconstituated panel mills. Forest products industries expected to provide wages exceeding the average manufacturing production wage include logging, softwood sawmills, millwork, softwood plywood--veneer, structural wood members, particle-board, wood partitions, pulp mills, paper mills, and paperboard mills. Industries expected to pay 90 percent of the average manufacturing production wage include wood kitchen cabinets, mobile homes, prefabricated wood buildings, and wood preservatives.

The Texarkana Wood Preserving Company Superfund site  

E-Print Network (OSTI)

is a former wood-treating site located in Texas that treated various wood products with chemical preservatives. These activities left behind contaminated soil and sludge, that led to contaminated groundwater. In 1990 Environmental Protection Agency (EPA) selected incineration as the means to clean up contaminated soil at this site. In 1994 Congressman Jim Chapman (D-Texas) asked the Office of Technology Assessment (OTA) to review alternative technologies that might be used instead of incineration at the Texarkana site. A second, separate study to assess the safety of incineration was also requested by Representative Chapman. This report reviews technologies available for hazardous waste cleanup at wood-treating sites throughout the United States. OTA found that there are many Superfund wood-treatment sites located in this country that are very similar in terms of the contaminants

Crop residues as a fuel for power generation  

DOE Green Energy (OSTI)

Crop residues could serve as an alternative energy source for producing electric power and heat in agricultural regions of the United States. Nearly 2 quads of residues are estimated to be available as a sustainable annual yield. These can substitute for up to one quad of conventional fuels used to generate electricity and up to an additional quad of petroleum and natural gas currently used for producing heat. The most promising routes to residue conversion appear to be regional generators sized in the megawatt range, and the mixing of residues with coal for burning in coal power plants. Costing farmers from $0.70 to $1.25 per million Btu, to harvest and prepare for use as a fuel, residues can be a competitive renewable energy supply.

Short rotation Wood Crops Program  

DOE Green Energy (OSTI)

This report synthesizes the technical progress of research projects in the Short Rotation Woody Crops Program for the year ending September 30, 1989. The primary goal of this research program, sponsored by the US Department of Energy's Biofuels and Municipal Waste Technology Division, is the development of a viable technology for producing renewable feedstocks for conversion to biofuels. One of the more significant accomplishments was the documentation that short-rotation woody crops total delivered costs could be $40/Mg or less under optimistic but attainable conditions. By taking advantage of federal subsidies such as those offered under the Conservation Reserve Program, wood energy feedstock costs could be lower. Genetic improvement studies are broadening species performance within geographic regions and under less-than-optimum site conditions. Advances in physiological research are identifying key characteristics of species productivity and response to nutrient applications. Recent developments utilizing biotechnology have achieved success in cell and tissue culture, somaclonal variation, and gene-insertion studies. Productivity gains have been realized with advanced cultural studies of spacing, coppice, and mixed-species trials. 8 figs., 20 tabs.

Levelized life-cycle costs for four residue-collection systems and four gas-production systems  

DOE Green Energy (OSTI)

Technology characterizations and life-cycle costs were obtained for four residue-collection systems and four gas-production systems. All costs are in constant 1981 dollars. The residue-collection systems were cornstover collection, wheat-straw collection, soybean-residue collection, and wood chips from forest residue. The life-cycle costs ranged from $19/ton for cornstover collection to $56/ton for wood chips from forest residues. The gas-production systems were low-Btu gas from a farm-size gasifier, solar flash pyrolysis of biomass, methane from seaweed farms, and hydrogen production from bacteria. Life-cycle costs ranged from $3.3/10/sup 6/ Btu for solar flash pyrolysis of biomass to $9.6/10/sup 6/ Btu for hydrogen from bacteria. Sensitivity studies were also performed for each system. The sensitivity studies indicated that fertilizer replacement costs were the dominate costs for the farm-residue collection, while residue yield was most important for the wood residue. Feedstock costs were most important for the flash pyrolysis. Yields and capital costs are most important for the seaweed farm and the hydrogen from bacteria system.

Use of Wood Energy in the United States –  

E-Print Network (OSTI)

The use of wood for energy – including the burning of solid wood and black liquor from pulping – has been growing at a rate significantly greater than that for all other uses such as lumber, pulp, or particleboard. in the United States, the end of most wood is not lumber or pulp and paper but feed for energy. In 1983, 155. 5 M Mg of wood were used for energy. This could threaten to increase the price of wood for those other uses, or it can stimulate us to seek more creative ways of using untapped wood resources for fuel. on the basis of estimates of heavy wood energy use relative to other uses for wood, and estimates of continuing high costs for fossil fuels, we suggest here the feasibility of meeting the demand for fuelwood through small-scale cooperatives. Such an approach can improve forestry practices and can avoid unduly increasing the cost of wood for other end uses.

An assessment of management practices of wood and wood-related wastes in the urban environment  

DOE Green Energy (OSTI)

The US Environmental Protection Agency estimates that yard waste{sup 1} accounts for approximately 16% of the municipal solid waste (MSW) stream (US EPA, 1994). Until recently, specific data and related information on this component of the (MSW) stream has been limited. The purposes of this study, phase two of the three-phase assessment of urban wood waste issues, are to assess and describe current alternatives to landfills for urban wood waste management; provide guidance on the management of urban wood waste to organizations that produce or manage wood waste; and clarify state regulatory and policy positions affecting these organizations. For this study, urban wood waste is defined as solid waste generated by tree and landscape maintenance services (public and private). Urban wood waste includes the following materials: unchipped mixed wood, unchipped logs, and unchipped tops and brush; clearing and grubbing waste; fall leaves and grass clippings; and chips and whole stumps. Construction and demolition debris and consumer-generated yard waste are not included in this study. Generators of urban wood waste include various organizations; municipal, county, and commercial tree care divisions; nurseries, orchards, and golf courses; municipal park and recreation departments; and electric and telephone utility power line maintenance, excavator and land clearance, and landscape organizations. (1) US EPA defines yard waste as ''yard trimmings'' which includes ''grass, leaves and tree brush trimmings from residential, institutional, and commercial sources.''

Materials - Recycling - Shredder Residue  

NLE Websites -- All DOE Office Websites (Extended Search)

Recovering Materials from Shredder Residue Recovering Materials from Shredder Residue Obsolete automobiles, home appliances and other metal-containing scrap are shredded for the recovery of metals. More than 50% of the material shredded is automobiles. In the United States, shredders generate about 5 million tons of shredder residue every year. Similar amounts are produced in Europe and in the Pacific Rim. Because recycling shredder waste has not been profitable, most of it ends up in landfills; smaller amounts are incinerated. Argonne researchers have developed and tested a process to recover polymers and metals from shredder residue. A 2-ton/hr pilot plant, consisting of a mechanical separation facility and a six-stage wet density/froth flotation plant, was built at Argonne. In the mechanical part of the plant, the shredder waste was separated into five primary components: a polymer fraction (about 45% by weight), a residual metals concentrate (about 10% by weight), a polyurethane foam portion (about 5% by weight), an organic-rich fraction (about 25% by weight) and a metal oxides fraction (about 15% by weight). The polymer fraction was then separated further in the wet density/froth flotation system to recover individual plastic types or compatible families of polymers.

Wood combustion systems: status of environmental concerns  

DOE Green Energy (OSTI)

This document addresses the uncertainties about environmental aspects of Wood Combustion Systems that remain to be resolved through research and development. The resolution of these uncertainties may require adjustments in the technology program before it can be commercialized. The impacts and concerns presented in the document are treated generically without reference to specific predetermined sites unless these are known. Hence, site-specific implications are not generally included in the assessment. The report consists of two main sections which describe the energy resource base involved, characteristics of the technology, and introduce the environmental concerns of implementing the technology; and which review the concerns related to wood combustion systems which are of significance for the environment. It also examines the likelihood and consequence of findings which might impede wood commercialization such as problems and uncertainties stemming from current or anticipated environmental regulation, or costs of potential environmental controls. This document is not a formal NEPA document. Appropriate NEPA documentation will be prepared after a formal wood combustion commercialization program is approved by DOE.

Fast Curing of Composite Wood Products  

SciTech Connect

The overall objective of this program is to develop low temperature curing technologies for UF and PF resins. This will be accomplished by: • Identifying the rate limiting UF and PF curing reactions for current market resins; • Developing new catalysts to accelerate curing reactions at reduced press temperatures and times. In summary, these new curing technologies will improve the strength properties of the composite wood products and minimize the detrimental effects of wood extractives on the final product while significantly reducing energy costs for wood composites. This study is related to the accelerated curing of resins for wood composites such as medium density fiberboard (MDF), particle board (PB) and oriented strandboard (OSB). The latter is frequently manufactured with a phenol-formaldehyde resin whereas ureaformaldehyde (UF) resins are usually used in for the former two grades of composite wood products. One of the reasons that hinder wider use of these resins in the manufacturing of wood composites is the slow curing speed as well as inferior bondability of UF resin. The fast curing of UP and PF resins has been identified as an attractive process development that would allow wood to be bonded at higher moisture contents and at lower press temperatures that currently employed. Several differing additives have been developed to enhance cure rates of PF resins including the use of organic esters, lactones and organic carbonates. A model compound study by Conner, Lorenz and Hirth (2002) employed 2- and 4-hydroxymethylphenol with organic esters to examine the chemical basis for the reported enhanced reactivity. Their studies suggested that the enhance curing in the presence of esters could be due to enhanced quinone methide formation or enhanced intermolecular SN2 reactions. In either case the esters do not function as true catalysts as they are consumed in the reaction and were not found to be incorporated in the polymerized resin product. An alternative approach to accelerated PF curing can be accomplished with the addition amines or amides. The later functionality undergoes base catalyzed hydrolysis yielding the corresponding carboxyl ate and free amine which rapidly reacts with the phenolic methylol groups facilitating polymerization and curing of the PF resin (Pizzi, 1997).

Effect of species and wood to bark ratio on pelleting of southern woods  

Science Conference Proceedings (OSTI)

Six common southern hardwoods and loblolly pine were pelleted in a laboratory pellet mill. The pellet furnishes were blended to test the effect of different wood to bark ratios on pellet durability and production rate. Included was a ratio chosen to simulate the wood to bark ratio found in whole-tree chips. This furnish produced good quality pellets for all species tested. Pelleting of the pure wood of hardwoods was not successful; furnish routinely blocked the pellet mill dies. Pure pine wood, however, did produce acceptable pellets. It was noted that, as lignin and extractive content increased above a threshold level, the precentage of fines produced in a pellet durability test increased. Thus, all pine and tupelo wood/bark mixes produces high fines. This reduces the desirability of the pellets in the marketplace. Further research is necessary to confirm this relationship. This study suggests that both tree species and wood/bark ratio affect the durability of pellets and the rate with which they can be produced in a laboratory pellet mill. 9 references.

Wood and energy in New Hampshire. Staff report  

SciTech Connect

Telephone surveys of New Hampshire households conducted in 1979 and 1980 indicate a transition to wood heating in response to a series of conventional energy price increases and uncertainty in conventional energy supplies. New Hampshire households consumed 394,000 cords of wood in the winter of 1978-79; 504,000 cords were burnt during the next winter. The airtight wood stove has become the most commonly used wood-burning apparatus. Survey data of residential wood cutting, purchasing, and burning were analyzed by household tenure, wood-burning apparatus, and county. Residential use of wood for energy constitutes a new demand on the forest resource, increases local income and employment, displaces fuel oil and electricity, and may compromise household safety.

Wood power - its potential in our energy crisis  

Science Conference Proceedings (OSTI)

Wood is meeting about 2% of total U.S. energy needs and may eventually supply up to 7% of our nation's energy. Many forms of direct combustion equipment are available for residential heating and range from supplemental wood-burning stoves to complete house-heating multi-fuel furnaces. A recent survey conducted in New York indicated that one-third of the people contacted used wood for home heating. The total amount of fuelwood used in New York State in 1978 amounted to 1,716,000 standard cords. A Wisconsin study indicates that more than 1.2 million cords of firewood were burned by Wisconsin households during the 1979-80 heating season. A Pennsylvania survey indicated that 22% of single family households used wood for home heating. Corning Glass Works recently conducted a wood-burning stove market survey and found that 18% of all U.S. households own wood-burning stoves. On the basis of cost per unit of heat, wood heat is cheaper than its next closest commonly available rival (fuel oil) and is also cheaper than anthracite coal and electricity. Industrial wood-burning furnaces are commonly incorporated into boiler systems. Nearly 1700 wood-fired boiler systems are in operation in the United States. The economic value of a wood fuel will depend on its heating value and moisture content. For an indsutry considering use of densified wood for fuel, there is a question of whether the added expense is justified by increased ease of handling and improved burning efficiency. Where high sulfur emissions from coal are a problem, burning sulfur-free pellets in combination with coal may be a solution. In Maine a $3 million pellet-making plant is producing 600 tons of pellets per day. Nationally, the overall generating capacity of all known electrical generating plants using wood and wood derived fuels is about 4500 megawatts. Wood can be processed to produce liquid fuels and other chemicals.

Referring to the industrial wood waste category (as dominant in the provincial district of Pesaro-Urbino, Marche Region, Italy), this paper deals with the experimental characterisation and the carrying out of non-controlled burning tests (at lab- and pilot-scale) for selected 'raw' and primarily 'engineered' ('composite') wood wastes. The property characterisation has primarily revealed the following aspects: potential influence on moisture content of local weather conditions at outdoor wood waste storage sites; generally, higher ash contents in 'engineered' wood wastes as compared with 'raw' wood wastes; and relatively high energy content values of 'engineered' wood wastes (ranging on the whole from 3675 to 5105 kcal kg{sup -1} for HHV, and from 3304 to 4634 kcal kg{sup -1} for LHV). The smoke qualitative analysis of non-controlled lab-scale burning tests has primarily revealed: the presence of specific organic compounds indicative of incomplete wood combustion; the presence exclusively in 'engineered' wood burning tests of pyrroles and amines, as well as the additional presence (as compared with 'raw' wood burning) of further phenolic and containing nitrogen compounds; and the potential environmental impact of incomplete industrial wood burning on the photochemical smog phenomenon. Finally, non-controlled pilot-scale burning tests have primarily given the following findings: emission presence of carbon monoxide indicative of incomplete wood combustion; higher nitrogen oxide emission values detected in 'engineered' wood burning tests as compared with 'raw' wood burning test; and considerable generation of the respirable PM{sub 1} fraction during incomplete industrial wood burning.

Pellet stoves wood energy for all  

Science Conference Proceedings (OSTI)

While it`s true that specialized pellet stoves, capable of burning fuels as diverse as reprocessed paper waste and feed corn, are expensive and occasionally clunky, they also represent one of the best hopes for introducing clean burning, reliable renewable energy to those now heating with gas and oil. This article explores the benefits and operation of the stoves including discussions of the following: ecological benefits, combustion, stove venting, ashes, costs, fuels, and the future of wood heat. 1 tab.

Baseline effects on carbon footprints of biofuels: The case of wood  

Science Conference Proceedings (OSTI)

As biofuel usage has boomed over the past decade, so has research and regulatory interest in its carbon accounting. This paper examines one aspect of that carbon accounting: the baseline, i.e. the reference case against which other conditions or changes can be compared. A literature search and analysis identified four baseline types: no baseline; reference point; marginal fossil fuel; and biomass opportunity cost. The fourth one, biomass opportunity cost, is defined in more detail, because this is not done elsewhere in the literature. The four baselines are then applied to the carbon footprint of a wood-fired power plant. The footprint of the resulting wood-fired electricity varies dramatically, according to the type of baseline. Baseline type is also found to be the footprint's most significant sensitivity. Other significant sensitivities are: efficiency of the power plant; the growth (or re-growth) rate of the forest that supplies the wood; and the residue fraction of the wood. Length of the policy horizon is also an important factor in determining the footprint. The paper concludes that because of their significance and variability, baseline choices should be made very explicit in biofuel carbon footprints. - Highlights: Black-Right-Pointing-Pointer Four baseline types for biofuel footprinting are identified. Black-Right-Pointing-Pointer One type, 'biomass opportunity cost', is defined mathematically and graphically. Black-Right-Pointing-Pointer Choice of baseline can dramatically affect the footprint result. Black-Right-Pointing-Pointer The 'no baseline' approach is not acceptable. Black-Right-Pointing-Pointer Choice between the other three baselines depends on the question being addressed.

Inexpensive solar-wood water heating combinations  

SciTech Connect

A promising batch heater recently built and now being tested consists of lengths of eight-inch galvanized culvert pipe painted with semiselective black coating, hooked in series and tied in as part of a passive closed loop, unpressurized solar-wood water heating combination. One 10-foot length of eight-inch culvert contains 14.6 gallons of water. Eight-inch culvert provides a near optimum surface area per unit volume ratio, resulting in quicker, more efficient solar water heating. Moreover, the proposed arrangement minimizes the mixing of hot with cold water as warm water is used, often a problem with many types of batch heaters. Details for constructing this type of batch heater are provided. The system is an unpressurized, closed loop set-up, which means that the same liquid circulates continually from solar heater to wood heater to storage tank heat exchanger. The collector design is a variation on the inverted batch heater which takes its inspiration from a number of solar designers of similar units and introduces several additional measures to take advantage of the wood heating connection and to improve the design based on operating experience.

Leonard Wood and the American Empire  

E-Print Network (OSTI)

During the ten years following the Spanish American War (1898 to 1908), Major General Leonard Wood served as the primary agent of American imperialism. Wood was not only a proconsul of the new American Empire; he was a symbol of the empire and the age in which he served. He had the distinction of directing civil and military government in Cuba and the Philippines where he implemented the imperial policies given to him by the administrations of William McKinley and Theodore Roosevelt. In Cuba, he labored to rebuild a state and a civil society crippled by decades of revolutionary ferment and guided the administration's policy through the dangerous channels of Cuban politics in a way that satisfied – at least to the point of avoiding another revolution – both the Cubans and the United States. In the Philippines, Wood took control of the Moro Province and attempted to smash the tribal-religious leadership of Moro society in order to bring it under direct American rule. His personal ideology, the imperial policies he shepherded, and the guidance he provided to fellow military officers and the administrations he served in matters of colonial administration and defense shaped the American Empire and endowed it with his personal stamp.

SRC Residual fuel oils  

DOE Patents (OSTI)

Coal solids (SRC) and distillate oils are combined to afford single-phase blends of residual oils which have utility as fuel oils substitutes. The components are combined on the basis of their respective polarities, that is, on the basis of their heteroatom content, to assure complete solubilization of SRC. The resulting composition is a fuel oil blend which retains its stability and homogeneity over the long term.

Wood Pulp Digetster Wall Corrosion Investigation  

DOE Green Energy (OSTI)

The modeling of the flow in a wood pulp digester is but one component of the investigation of the corrosion of digesters. This report describes the development of a Near-Wall-Model (NWM) that is intended to couple with a CFD model that determines the flow, heat, and chemical species transport and reaction within the bulk flow of a digester. Lubrication theory approximations were chosen from which to develop a model that could determine the flow conditions within a thin layer near the vessel wall using information from the interior conditions provided by a CFD calculation of the complete digester. The other conditions will be determined by coupled solutions of the wood chip, heat, and chemical species transport and chemical reactions. The NWM was to couple with a digester performance code in an iterative fashion to provide more detailed information about the conditions within the NW region. Process Simulations, Ltd (PSL) is developing the digester performance code. This more detailed (and perhaps more accurate) information from the NWM was to provide an estimate of the conditions that could aggravate the corrosion at the wall. It is intended that this combined tool (NWM-PSL) could be used to understand conditions at/near the wall in order to develop methods to reduce the corrosion. However, development and testing of the NWM flow model took longer than anticipated and the other developments (energy and species transport, chemical reactions and linking with the PSL code) were not completed. The development and testing of the NWM are described in this report. In addition, the investigation of the potential effects of a clear layer (layer reduced in concentration of wood chips) near the wall is reported in Appendix D. The existence of a clear layer was found to enhance the flow near the wall.

Wood Fired Steam Plants in Georgia  

E-Print Network (OSTI)

During the 1970's, Georgia industry experienced problems obtaining fuel for operations on several occasions. In particular, the very cold winter of 1976-77 resulted in natural gas curtailments which virtually shut down many of Georgia's industries. Shortly after that time, Georgia Tech and the Georgia Forestry Commission embarked on a number of projects directed toward providing the use of wood as an industrial energy source. This paper will present an overview of these programs with an emphasis on three demonstration plants that were built with partial financing by state and federal government.

Global carbon impacts of using forest harvest residues for district heating in Vermont  

DOE Green Energy (OSTI)

Forests in Vermont are selectively logged periodically to generate wood products and useful energy. Carbon remains stored in the wood products during their lifetime and in fossil fuel displaced by using these products in place of energy-intensive products. Additional carbon is sequestered by new forest growth, and the forest inventory is sustained using this procedure. A significant portion of the harvest residue can be used as biofuel in central plants to generate electricity and thermal energy, which also displaces the use of fossil fuels. The impact of this action on the global carbon balance was analyzed using a model derived from the Graz/Oak Ridge Carbon Accounting Model (GORCAM). The analysis showed that when forests are harvested only to manufacture wood products, more than 100 years are required to match the sequestered carbon present if the forest is left undisturbed. If part of the harvest residue is collected and used as biofuel in place of oil or natural gas, it is possible to reduce this time to about 90 years, but it is usually longer. Given that harvesting the forest for products will continue, carbon emission benefits relative to this practice can start within 10 to 70 years if part of the harvest residue is used as biofuel. This time is usually higher for electric generation plants, but it can be reduced substantially by converting to cogeneration operation. Cogeneration makes possible a ratio of carbon emission reduction for district heating to carbon emission increase for electricity generation in the range of 3 to 5. Additional sequestering benefits can be realized by using discarded wood products as biofuels.

Ionic liquid pretreatment of poplar wood at room temperature: swelling and incorporation of nanoparticles  

DOE Green Energy (OSTI)

Lignocellulosic biomass represents a potentially sustainable source of liquid fuels and commodity chemicals. It could satisfy the energy needs for transportation and electricity generation, while contributing substantially to carbon sequestration and limiting the accumulation of greenhouse gases in the atmosphere. Potential feedstocks are abundant and include crops, agricultural wastes, forest products, grasses, and algae. Among those feedstocks, wood is mainly constituted of three components: cellulose, hemicellulose, and lignin. The conversion process of lignocellulosic biomass typically consists of three steps: (1) pretreatment; (2) hydrolysis of cellulose and hemicellulose into fermentable sugars; and (3) fermentation of the sugars into liquid fuels (ethanol) and other commodity chemicals. The pretreatment step is necessary due to the complex structure of the plant cell wall and the chemical resistance of lignin. Most current pretreatments are energy-intensive and/or polluting. So it is imperative to develop new pretreatments that are economically viable and environmentally friendly. Recently, ionic liquids have attracted considerable interest, due to their ability to dissolve biopolymers, such as cellulose, lignin, native switchgrass, and others. Ionic liquids are also considered green solvents, since they have been successfully recycled at high yields for further use with limited efficiency loss. Also, a few microbial cellulases remain active at high ionic liquid concentration. However, all studies on the dissolution of wood in ionic liquids have been conducted so far at high temperatures, typically above 90 C. Development of alternative pretreatments at room temperature is desirable to eliminate the additional energy cost. In this study, thin sections of poplar wood were swollen at room temperature by a 3 h ionic liquid (1-ethyl-3-methylimidazolium acetate or EMIMAc) pretreatment. The pretreated sample was then exposed to an aqueous suspension of nanoparticles that resulted in the sample contraction and the deposition of nanoparticles onto the surface and embedded into the cell wall. To date, both silver and gold particles ranging in size from 40-100 nm have been incorporated into wood. Penetration of gold nanoparticles of 100 nm diameter in the cell walls was best confirmed by near-infrared confocal Raman microscopy, since the deposition of gold nanoparticles induces a significant enhancement of the Raman signal from the wood in their close proximity, an enhancement attributed to the surface-enhanced Raman effect (SERS). After rinsing with water, scanning electron microscopy (SEM) and Raman images of the same areas show that most nanoparticles remained on the pretreated sample. Raman images at different depths reveal that a significant number of nanoparticles were incorporated into the wood sample, at depths up to 4 {micro}m, or 40 times the diameter of the nanoparticles. Control experiments on an untreated wood sample resulted in the deposition of nanoparticles only at the surface and most nanoparticles were removed upon rinsing. This particle incorporation process enables the development of new pretreatments, since the nanoparticles have a high surface-to-volume ratio and could be chemically functionalized. Other potential applications for the incorporated nanoparticles include isotope tracing, catalysis, imaging agents, drug-delivery systems, energy-storage devices, and chemical sensors.

A Wood-Fired Gas Turbine Plant  

E-Print Network (OSTI)

This paper covers the research and development of a wood-fired gas turbine unit that is used for generating electricity. The system uses one large cyclonic combustor and a cyclone cleaning system in series to provide hot gases to drive an Allison T-56 aircraft engine (the industrial version is the 501-k). A Westinghouse 3,000-kW generator is used on the prototype facility with a Philadelphia gear system reducing the 14,000-rpm turbine output speed to the 3,600-rpm generator operating speed. Fuel is fed into the combustor by a rotary valve system. The swirling effect of the cyclone combustor ensures that residence time is adequate to completely burn all solid particles in the combustor ahead of the cyclone filter. Burning of particles on the metal walls of the cyclone filter could cause overheating and deterioration of the walls. This wood-fired gas turbine unit could provide a low cost source of power for areas where conventional methods are now prohibitive and provide a means for recovering energy from a source that now poses disposal problems.

Modelling piloted ignition of wood and plastics  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer We model piloted ignition times of wood and plastics. Black-Right-Pointing-Pointer The model is applied on a packed bed. Black-Right-Pointing-Pointer When the air flow is above a critical level, no ignition can take place. - Abstract: To gain insight in the startup of an incinerator, this article deals with piloted ignition. A newly developed model is described to predict the piloted ignition times of wood, PMMA and PVC. The model is based on the lower flammability limit and the adiabatic flame temperature at this limit. The incoming radiative heat flux, sample thickness and moisture content are some of the used variables. Not only the ignition time can be calculated with the model, but also the mass flux and surface temperature at ignition. The ignition times for softwoods and PMMA are mainly under-predicted. For hardwoods and PVC the predicted ignition times agree well with experimental results. Due to a significant scatter in the experimental data the mass flux and surface temperature calculated with the model are hard to validate. The model is applied on the startup of a municipal waste incineration plant. For this process a maximum allowable primary air flow is derived. When the primary air flow is above this maximum air flow, no ignition can be obtained.

Steam gasification of wood in the presence of catalysts  

SciTech Connect

Catalytic steam gasification of wood, including sawdust, chipped forest slash, and mill shavings, is being investigated. Results of laboratory, process development unit (PDU), and feasibility studies illustrate attractive processes for conversion of wood to methanol and a substitute natural gas (SNG). Recent laboratory studies developed a long-lived alloy catalyst for generation of a methanol synthesis gas by steam gasification of wood. Modification of the PDU for operation at 10 atm (150 psia) is nearly complete. The modified PDU will be operated at the elevated pressure to confirm yields and design parameters used in process feasibility studies. Feasibility studies were completed on wood-to-methane (SNG) and wood-to-methanol plants with capacities of 2000 and 200 oven dried tons (1800 and 180 metric t) per day using catalytic gasification. The results showed that generation of methanol on the large scale is economically viable today while SNG generation is competitive with future prices.

Effects of wood fuel use on plant management  

SciTech Connect

During the winter of 1979-80, about 20% of homeowners in the New England region relied on wood fuel as their primary source of heat; an additional 30% used wood heat on a supplementary basis. The demand for wood put a great strain on the New England forests. However, experts in forest management believe that with proper management and utilization, national forest growth could replace as much as four billion gpy of oil by 2023. Implications for the forests of the Upper Great Lakes region of increased use of public and private woodlands for fuel are examined. Conflicts that could arise with the tourist and recreation industry, and with wilderness preservation interests, and discussed. Wood wastes generated by timber harvesting, sawmills, and lumber manufacturing could be collected and used as fuel, thus reducing the amount of raw wood resources needed to fill the increasing demand.

Performance of bolted wood connections using supplemental confining devices  

E-Print Network (OSTI)

In the aftermath of the 1994 Northridge Earthquake, extensive field investigations revealed damage in wood frame construction in the form of splitting the 2x4 or 2x6 dimension lumber sill plates along the line of anchor bolts which typically connect shear walls to the masonry or concrete foundation. This paper presents an experimental investigation on the performance of bolted wood connections at the yield and ultimate limit states during monotonic and incremental quasi-static reversed cyclic loading and suggests possible retrofit strategies for their improved seismic performance. Proposed retrofit strategies are based on providing confinement to the bolted wood member using metal reinforcing ;traps and reinforcing clamps to increase the deformation capability and energy dissipation capacity of the connection, while maintaining substantial levels of connection strength. Connection types included in the investigation are: (1) double shear wood-to-wood connections; and (2) single shear simulated sill plate-to-concrete foundation connections.

Implementing Strategies for Drying and Pressing Wood Without Emissions Controls  

DOE Green Energy (OSTI)

Drying and pressing wood for the manufacture of lumber, particleboard, oriented strand board (OSB), veneer and medium density fiberboard (MDF) release volatile organic compounds (VOCs) into the atmosphere. These emissions require control equipment that are capital-intensive and consume significant quantities of natural gas and electricity. The objective of our work was to understand the mechanisms through which volatile organic compounds are generated and released and to develop simple control strategies. Of the several strategies developed, two have been implemented for OSB manufacture over the course of this study. First, it was found that increasing final wood moisture by about 2-4 percentage points reduced the dryer emissions of hazardous air pollutants by over 70%. As wood dries, the escaping water evaporatively cools the wood. This cooling tapers off wood when the wood is nearly dry and the wood temperature rises. Thermal breakdown of the wood tissue occurs and VOCs are released. Raising the final wood moisture by only a few percentage points minimizes the temperature rise and reduces emissions. Evaporative cooling also impacts has implications for VOC release from wood fines. Flaking wood for OSB manufacture inevitable generates fines. Fines dry out rapidly because of their high surface area and evaporative cooling is lost more rapidly than for flakes. As a result, fines emit a disproportionate quantity of VOCs. Fines can be reduced in two ways: through screening of the green furnish and through reducing their generation during flaking. The second approach is preferable because it also increased wood yield. A procedure to do this by matching the sharpness angle of the flaker knife to the ambient temperature was also developed. Other findings of practical interests are as follows: Dielectric heating of wood under low-headspace conditions removes terpenes and other extractives from softwood; The monoterpene content in trees depend upon temperature and seasonal effects; Method 25A emissions from lumber drying can be modeled from a knowledge of the airflow through the kiln; A heat transfer model shows that VOCs released during hot-pressing mainly originate from the surface of the board; and Boiler ash can be used to adsorb formaldehyde from air streams.

Homeowners energy conservation and consumption behavior: wood users and non/low wood users  

SciTech Connect

Relationships among energy expenditure, energy consumption, energy-budget share, energy managerial practices, housing, and household-membership factors for non/low wood-user and high wood-user households were examined to explain substitution of fuelwood for primary fuels. Data were from a nationwide representative sample of 1599 homeowners collected by the Department of Energy in 1982-1983 Residential Energy Conservation Survey. In three multivariate regression models, different dependent variables - energy expenditure, energy consumption, and energy budget share, were used. The same independent variables - housing factors, household energy managerial practices, and household membership factors, were used in the three models. Finally, in a fourth model, discriminant analysis with the dichotomous criterion variable of non/low or high wood users and significant variables from the multivariate regressions models were used to explain 34% of the variance. The amount of space heated, their appliance use, whether they had teenage children, and if they were single-earner households were significant explanatory variables in all four models.

Wood-Polymer composites obtained by gamma irradiation  

Science Conference Proceedings (OSTI)

In this work we impregnate three Peruvian woods (Calycophy spruceanum Be, Aniba amazonica Meiz and Hura crepitans L) with styrene-polyester resin and methyl methacrylate. The polymerization of the system was promoted by gamma radiation and the experimental optimal condition was obtained with styrene-polyester 1:1 and 15 kGy. The obtained composites show reduced water absorption and better mechanical properties compared to the original wood. The structure of the wood-polymer composites was studied by light microscopy. Water absorption and hardness were also obtained.

Method for lowering the VOCS emitted during drying of wood products  

DOE Patents (OSTI)

The present invention is directed to a method for removal of VOCs from wood products prior to drying the wood products. The method of the invention includes the steps of providing a chamber having an opening for receiving wood and loading the chamber with green wood. The wood is loaded to an extent sufficient to provide a limited headspace in the chamber. The chamber is then closed and the wood is heated in the chamber for a time and at a temperature sufficient to saturate the headspace with moisture and to substantially transfer VOCs from the wood product to the moisture in the headspace.

Test evaluation of a laminated wood wind turbine blade concept  

SciTech Connect

Because of the high stiffness and fatigue strength of wood (as compared to density) along with the low cost manufacturing techniques available, a laminated wood wind turbine blade application has been studied. This report presents the results of the testing performed on elements of the wood blade-to-hub transition section which uses steel studs cast into a laminated wood spar with a filled epoxy. Individual stud samples were tested for both ultimate load carrying capability and fatigue strength. A one-time pull-out load of 78,000 lb was achieved for a 15 in. long stud with a diameter of 1 in. Tension-tension fatigue indicated that peak loads on the order of 40% of ultimate could be maintained as an endurance limit (mean load = 20,000 lb, cyclic load = +-15,000 lb). Following the individual stud testing, a full-scale inboard blade section (20 ft in length) was tested.

Final Report: Development of Renewable Microbial Polyesters for Cost Effective and Energy- Efficient Wood-Plastic Composites  

SciTech Connect

In this project, we proposed to produce wood fiber reinforced thermoplastic composites (WFRTCs) using microbial thermoplastic polyesters in place of petroleum-derived plastic. WFRTCs are a rapidly growing product area, averaging a 38% growth rate since 1997. Their production is dependent on substantial quantities of petroleum based thermoplastics, increasing their overall energy costs by over 230% when compared to traditional Engineered Wood Products (EWP). Utilizing bio-based thermoplastics for these materials can reduce our dependence on foreign petroleum. We have demonstrated that biopolymers (polyhydroxyalkanoates, PHA) can be successfully produced from wood pulping waste streams and that viable wood fiber reinforced thermoplastic composite products can be produced from these materials. The results show that microbial polyester (PHB in this study) can be extruded together with wastewater-derived cell mass and wood flour into deck products having performance properties comparable to existing commercial HDPE/WF composite products. This study has thus proven the underlying concept that the microbial polyesters produced from waste effluents can be used to make cost-effective and energy-efficient wood-plastic composites. The cost of purified microbial polyesters is about 5-20 times that of HDPE depending on the cost of crude oil, due to high purification (40%), carbon substrate (40%) and sterilized fermentation (20%) costs for the PHB. Hence, the ability to produce competitive and functional composites with unpurified PHA-biomass mixtures from waste carbon sources in unsterile systems—without cell debris removal—is a significant step forward in producing competitive value-added structural composites from forest products residuals using a biorefinery approach. As demonstrated in the energy and waste analysis for the project, significant energy savings and waste reductions can also be realized using this approach. We recommend that the next step for development of useful products using this technology is to scale the technology from the 700-L pilot reactor to a small-scale production facility, with dedicated operation staff and engineering controls. In addition, we recommend that a market study be conducted as well as further product development for construction products that will utilize the unique properties of this bio-based material.

Extracellular oxidative metabolism of wood decay fungi  

DOE Green Energy (OSTI)

Substantial progress has been made toward understanding the fundamental physiology and genetics of wood decay fungi, microbes that are capable of degrading all major components of plant cell walls. Efficient utilization of lignocellulosic biomass has been hampered in part by limitations in our understanding of enzymatic mechanisms of plant cell wall degradation. This is particularly true of woody substrates where accessibility and high lignin content substantially complicate enzymatic 'deconstruction'. The interdisciplinary research has illuminated enzymatic mechanisms essential for the conversion of lignocellulosics to simple carbohydrates and other small molecular weight products. Progress was in large part dependent on substantial collaborations with the Department of Energy's Joint Genome Institute (JGI) in Walnut Creek and Los Alamos, as well as the Catholic University, Santiago, Chile, the Royal Institute of Technology, Stockholm, the University of Minnesota, St. Paul, and colleagues at the University of Wisconsin and the Forest Products Laboratory. Early accomplishments focused on the development of experimental tools (2, 7, 22, 24-26, 32) and characterization of individual genes and enzymes (1, 3-5, 8, 9, 11, 14, 15, 17, 18, 23, 27, 33). In 2004, the genome of the most intensively studied lignin-degrading fungus, Phanerochaete chrysosporium, was published (21). This milestone lead to additional progress on this important model system (6, 10, 12, 13, 16, 28-31) and was further complemented by genome analysis of other important cellulose-degrading fungi (19, 20). These accomplishments have been highly cited and have paved the way for whole new research areas.

Moisture Distribution and Flow During Drying of Wood and Fiber  

DOE Green Energy (OSTI)

New understanding, theories, and techniques for moisture flow and distribution were developed in this research on wood and wood fiber. Improved understanding of the mechanisms of flake drying has been provided. Observations of flake drying and drying rate curves revealed that rate of moisture loss consisted of two falling rate periods and no constant rate drying period was observed. Convective heat transfer controls the first period, and bound water diffusion controls the second period. Influence of lower drying temperatures on bending properties of wood flakes was investigated. Drying temperature was found to have a significant influence on bending stiffness and strength. A worksheet for calculation of the energy required to dry a single strandboard flake was developed but has not been tested in an industrial setting yet. A more complete understanding of anisotropic transverse shrinkage of wood is proposed based on test results and statistical analysis. A simplified mod el of a wood cell's cross-section was drawn for calculating differential transverse shrinkage. The model utilizes cell wall thickness and microfibrillar packing density and orientation. In spite of some phenomena of cell wall structure not yet understood completely, the results might explain anisotropic transverse shrinkage to a major extent. Boundary layer theory was found useful for evaluating external moisture resistance during drying. Simulated moisture gradients were quire comparable to the actual gradients in dried wood. A mathematical procedure for determining diffusion and surface emission coefficients was also developed. Thermal conductivity models of wood derived from its anatomical structure were created and tested against experimental values. Model estimations provide insights into changes in heat transfer parameters during drying. Two new techniques for measuring moisture gradients created in wood during drying were developed. A new technique that utilizes optical properties of cobalt chloride was developed for nondestructive determination of surface moisture content. Fundamental new understanding of drying characteristics in wood and fiber has been provided that can be used by researchers to improve drying of wood and fiber. The three techniques for measuring moisture content and gradients provided in this study are efficient, practical, and economical - easy to apply by industry and researchers. An energy consumption worksheet is provided as a first step toward reducing energy consumed during drying of lumber and strandboard flakes. However, it will need additional verification and testing.

DISSOLUTION OF NEPTUNIUM OXIDE RESIDUES  

Science Conference Proceedings (OSTI)

This report describes the development of a dissolution flowsheet for neptunium (Np) oxide (NpO{sub 2}) residues (i.e., various NpO{sub 2} sources, HB-Line glovebox sweepings, and Savannah River National Laboratory (SRNL) thermogravimetric analysis samples). Samples of each type of materials proposed for processing were dissolved in a closed laboratory apparatus and the rate and total quantity of off-gas were measured. Samples of the off-gas were also analyzed. The quantity and type of solids remaining (when visible) were determined after post-dissolution filtration of the solution. Recommended conditions for dissolution of the NpO{sub 2} residues are: Solution Matrix and Loading: {approx}50 g Np/L (750 g Np in 15 L of dissolver solution), using 8 M nitric acid (HNO{sub 3}), 0.025 M potassium fluoride (KF) at greater than 100 C for at least 3 hours. Off-gas: Analysis of the off-gas indicated nitric oxide (NO), nitrogen dioxide (NO{sub 2}) and nitrous oxide (N{sub 2}O) as the only identified components. No hydrogen (H{sub 2}) was detected. The molar ratio of off-gas produced per mole of Np dissolved ranged from 0.25 to 0.4 moles of gas per mole of Np dissolved. A peak off-gas rate of {approx}0.1 scfm/kg bulk oxide was observed. Residual Solids: Pure NpO{sub 2} dissolved with little or no residue with the proposed flowsheet but the NpCo and both sweepings samples left visible solid residue after dissolution. For the NpCo and Part II Sweepings samples the residue amounted to {approx}1% of the initial material, but for the Part I Sweepings sample, the residue amounted to {approx}8 % of the initial material. These residues contained primarily aluminum (Al) and silicon (Si) compounds that did not completely dissolve under the flowsheet conditions. The residues from both sweepings samples contained minor amounts of plutonium (Pu) particles. Overall, the undissolved Np and Pu particles in the residues were a very small fraction of the total solids.

A distributed approach to accounting for carbon in wood products  

SciTech Connect

With an evolving political environment of commitments to limit emissions of greenhouse gases, and of markets to trade in emissions permits, there is growing scientific, political, and economic need to accurately evaluate carbon (C) stocks and flows especially those related to human activities. One component of the global carbon cycle that has been contentious is the stock of carbon that is physically held in harvested wood products. The carbon stored in wood products has been sometimes overlooked, but the amount of carbon contained in wood products is not trivial, it is increasing with time, and it is significant to some Parties. This paper is concerned with accurate treatment of harvested wood products in inventories of CO2 emissions to the atmosphere. The methodologies outlined demonstrate a flexible way to expand current methods beyond the assumption of a simple, first-order decay to include the use of more accurate and detailed data while retaining the simplicity of simple formulas. The paper demonstrates that a more accurate representation of decay time can have significant economic implications in a system where emissions are taxed or emissions permits are traded. The method can be easily applied using only data on annual production of wood products and two parameters to characterize their expected lifetime. These methods are not specific to wood products but can be applied to long-lived, carbon-containing products from sources other than wood, e.g. long-lived petrochemical products. A single unifying approach that is both simple and flexible has the potential to be both more accurate in its results, more efficient in its implementation, and economically important to some Parties.

Cofiring Wood and Coal to Stoker Boilers in Pittsburgh  

DOE Green Energy (OSTI)

The prime objective of the University of Pittsburgh's overall wood/coal cofiring program is the successful introduction of commercial cofiring of urban wood wastes into the stoker boilers of western Pennsylvania. Central to this objective is the demonstration test at the Pittsburgh Brewing Company. In this test the project team is working to show that two commercially-available clean wood wastes - tub-ground pallet waste and chipped clearance wood - can be included in the fuel fed daily to an industrial stoker boiler. Irrespective of its economic outcome, the technical success of the demonstration at the brewery will allow the local air quality regulation agency to permit a parametric test at the Bellefield Boiler Plant. The objective of this test is to obtain comprehensive data on all key parameters of this operational boiler while firing wood with coal. The data would then be used for thorough generic technical and economic analyses. The technical analysis would be added to the open literature for the general planning and operational guidance for boiler owners and operators. The economic analysis would gage the potential for providing this stoker fuel commercially in an urban setting and for purchasing it regularly for combustion in an urban stoker boiler.

Chemistry of combined residual chlorination  

DOE Green Energy (OSTI)

The decay of the combined chlorine residual was investigated in this work. Recent concerns about the formation of undesirable compounds such as chloroform with free residual chlorination have focused attention on the alternative use of combined residual chlorination. This work investigates the applicability of reactions proposed to describe the transformations and decay of the combined residual with time. Sodium hypochlorite was added to buffered solutions of ammonia with the chlorine residual being monitored over periods extending up to 10 days. The reaction was studied at four initial concentrations of hypochlorite of 100, 50, 25 and 10 mg/L as Cl/sub 2/ with molar application ratios of chlorine to ammonia, defined herein as M ratios, of 0.90, 0.50, 0.25 and 0.05 at each hypochlorite dose. Sixty-eight experiments were conducted at the pH of 6.6 and 7.2. The conclusions are: (1) in the absence of free chlorine, the concentration of NH/sub 3/ does not seem to affect the rate of disappearance of the residual other than through the formation of NHCl/sub 2/ by NH/sub 2/Cl hydrolysis; (2) the reaction between NHCl/sub 2/ and NH/sub 4//sup +/ to form NH/sub 2/Cl is either much slower than reported by Gray et. al. or the mechanism is different with a rate limiting step not involving NH/sub 3/ or NH/sub 4//sup +/; (3) a redox reaction in addition to the first-order decomposition of NHCl/sub 2/ appears necessary. Model simulation results indicated that a reaction of the type NH/sub 2/Cl + NHCl/sub 2/ ..-->.. P added to the first-order NHCl/sub 2/ decomposition can explain the results observed except at the higher chlorine doses.

Wood for energy and rural development: the Philippine experience  

Science Conference Proceedings (OSTI)

The Philippine wood energy programme (dendro-thermal system) was originally developed as a source of energy independent of imported oil, and at a lower cost than oil. It has social benefits: new jobs, land distribution, rural income increment, and reforestation by tree farmers. Tree farming, its administration and organization of farmer institutions are essential to the programme, as are the development of farming techniques to produce energy, trees (growth of ipil-ipil), and an improved tree growth rate. An analysis of the economics of wood energy led to the conclusion that raw wood fuel can be cheaper than oil. In estimated costs of electricity, the dendro-thermal plants can produce power at competitive rates. 36 references.

Energy Supply- Production of Fuel from Agricultural and Animal Waste  

DOE Green Energy (OSTI)

The Society for Energy and Environmental Research (SEER) was funded in March 2004 by the Department of Energy, under grant DE-FG-36-04GO14268, to produce a study, and oversee construction and implementation, for the thermo-chemical production of fuel from agricultural and animal waste. The grant focuses on the Changing World Technologies (CWT) of West Hempstead, NY, thermal conversion process (TCP), which converts animal residues and industrial food processing biproducts into fuels, and as an additional product, fertilizers. A commercial plant was designed and built by CWT, partially using grant funds, in Carthage, Missouri, to process animal residues from a nearby turkey processing plant. The DOE sponsored program consisted of four tasks. These were: Task 1 Optimization of the CWT Plant in Carthage - This task focused on advancing and optimizing the process plant operated by CWT that converts organic waste to fuel and energy. Task 2 Characterize and Validate Fuels Produced by CWT - This task focused on testing of bio-derived hydrocarbon fuels from the Carthage plant in power generating equipment to determine the regulatory compliance of emissions and overall performance of the fuel. Task 3 Characterize Mixed Waste Streams - This task focused on studies performed at Princeton University to better characterize mixed waste incoming streams from animal and vegetable residues. Task 4 Fundamental Research in Waste Processing Technologies - This task focused on studies performed at the Massachusetts Institute of Technology (MIT) on the chemical reformation reaction of agricultural biomass compounds in a hydrothermal medium. Many of the challenges to optimize, improve and perfect the technology, equipment and processes in order to provide an economically viable means of creating sustainable energy were identified in the DOE Stage Gate Review, whose summary report was issued on July 30, 2004. This summary report appears herein as Appendix 1, and the findings of the report formed the basis for much of the subsequent work under the grant. An explanation of the process is presented as well as the completed work on the four tasks.

Greenhouse gases and agriculture. Book chapter  

SciTech Connect

Agriculture ranks third in its contribution to Earth's anthropogenically enhanced greenhouse effect. (Energy use and production and chlorofluorocarbons are ranked first and second, respectively.) Specifically, greenhouse gas sources and sinks are increased, and sinks are decreased, by conversion of land to agricultural use, using fertilizers, cultivating paddy rice, producing other plant and animal crops, and by creating and managing animal and plant wastes. However, some of these same activities increase greenhouse gas sinks and decrease greenhouse gas sources so the net effects are not obvious. The paper identifies the agricultural inputs, outputs, and wastes that alter atmospheric concentrations of carbon dioxide, methane, and nitrous oxides, and discusses agriculture's net impact on greenhouse gas fluxes.

Methanol production from eucalyptus wood chips. Attachment VIII. The wood-fueled gasification system, Evergreen Energy Corporation's final engineering report  

DOE Green Energy (OSTI)

Evergreen Energy Corporation provided projected cost and operating data on the Evergreen/Texaco entrained-bed wood gasification system currently under development as an alternative to the state-of-the-art fixed-bed wood gasification system proposed by Davy McKee. Overall capital costs for the total plant remain about the same at approx. $250 million. The Evergreen/Texaco system will provide significant capital cost savings in the gasifiers, gas cleanup, and waste water treatment sections, and eliminate the need for a large off-site wood-fired power boiler. These reductions are offset by higher investments in the feedstock preparation, drying, and feeding section plus the need for a larger air separation plant and compressor to supply oxygen at high pressure to the gasifier.

Comparative Sugar Recovery and Fermentation Data Following Pretreatment of Poplar Wood by Leading Technologies  

SciTech Connect

Through a Biomass Refining Consortium for Applied Fundamentals and Innovation among Auburn University, Dartmouth College, Michigan State University, the National Renewable Energy Laboratory, Purdue University, Texas A&M University, the University of British Columbia, and the University of California at Riverside, leading pretreatment technologies based on ammonia fiber expansion, aqueous ammonia recycle, dilute sulfuric acid, lime, neutral pH, and sulfur dioxide were applied to a single source of poplar wood, and the remaining solids from each technology were hydrolyzed to sugars using the same enzymes. Identical analytical methods and a consistent material balance methodology were employed to develop comparative performance data for each combination of pretreatment and enzymes. Overall, compared to data with corn stover employed previously, the results showed that poplar was more recalcitrant to conversion to sugars and that sugar yields from the combined operations of pretreatment and enzymatic hydrolysis varied more among pretreatments. However, application of more severe pretreatment conditions gave good yields from sulfur dioxide and lime, and a recombinant yeast strain fermented the mixed stream of glucose and xylose sugars released by enzymatic hydrolysis of water washed solids from all pretreatments to ethanol with similarly high yields. An Agricultural and Industrial Advisory Board followed progress and helped steer the research to meet scientific and commercial needs.

Predicting Current Serviceability And Residual Service Life Of Plywood Roof Sheathing Using  

E-Print Network (OSTI)

This report presents the findings and implications of a 10-year research program, carried out at the USDA Forest Service, Forest Products Laboratory, to develop kinetics-based service-life models for untreated and fire-retardant- (FR) treated plywood roof sheathing exposed to elevated in-service temperatures. This program was initiated because some FR-treated sheathing products were experiencing significant thermal degrade and needed to be replaced. This 10-year research program systematically identified the cause of the degradation and has resulted in new acceptance and performance standards and revisions to U.S. building codes. The strength loss was cumulatively related to FR chemistry, thermal exposure during pretreatment, treatment, and post-treatment processing, and in-service exposure. Quantitatively, a kinetics-based approach could be used to predict strength loss of plywood based on its time-- temperature exposure history. The research program then developed models to assess current condition, predict future hazard based on past service life, and predict residual serviceability of untreated and FR-treated plywood used as structural roof sheathing. Findings for each of these subjects are briefly described in this report. Results of research programs like this one can be used to extend the service life of wood by providing engineers with an estimate of residual serviceability and thereby avoiding premature removal. Many of the approaches in these kinetics-based servicelife models for plywood roof sheathing are directly applicable to the development of predictive durability models for wood and wood composite roof and wall sheathing that has been exposed to moisture and has eventually decayed. When those models are developed, they will help building code officials, ...

Short rotation wood crops program: Annual progress report for 1986  

DOE Green Energy (OSTI)

This report describes accomplishments in the Short Rotation Woody Crops Program (SRWCP) for the year ending September 30, 1986. The program is sponsored by the US Department of Energy's Biofuels and Municipal Waste Technology Division and consists of research projects at 29 institutions and corporations. The SRWCP is an integrated program of research and development devoted to a single objective: improving the productivity, cost efficiency, and fuel quality of wood energy crops as feedstocks for conversion to liquid and gaseous fuels. SRWCP directives have shifted from species-screening and productivity evaluations to large-scale viability trials of model species selected for their productivity potential and environmental compatibility. Populus was chosen the lead genera of five model species, and initial steps were taken toward organizing a Populus Research Consortium. Production yields from SRWCP research plots and coppice studies are discussed along with new efforts to model growth results and characteristics on a tree and stand basis. Structural and chemical properties of short-rotation intensive culture wood have been evaluated to determine the desirability of species traits and the potential for genetic improvements. Innovative wood energy crop handling techniques are presented as significant cost reduction measures. The conclusion is that new specialized wood energy crops can be feasible with the advances that appear technically possible over the next 10 years. 34 refs., 9 figs., 7 tabs.

Temperature Measurements in Full-Scale Wood Stud Shear Walls  

E-Print Network (OSTI)

This report presents the results of 10 full-scale fire resistance tests conducted at the National Fire Laboratory on load-bearing gypsum board protected, wood stud shear wall assemblies with and without resilient channels on the fire-exposed side. The two assembly arrangements studied were: symmetrical installation 1x1 (one layer of gypsum board on each of the exposed and unexposed sides) and asymmetrical installation of the shear membrane (one layer of gypsum board on both the exposed and unexposed sides and a shear wall membrane as a base layer alternating between the exposed (2x1) and unexposed sides (1x2)) on a wood stud frame. The gypsum board was 12.7 mm thick Type X. The insulations used were glass and rock fibres. The shear membranes used were plywood and oriented strand board (OSB). Tests were conducted to determine the effects of the placement of the shear membrane on the exposed/unexposed face, type of shear membrane, insulation type, load intensity and resilient channel installations on the fire resistance of gypsum board protected, wood stud shear wall assemblies. Details of the results, including the temperatures and deflections measured during the fire tests, are presented.

A stove or furnace for efficient combustion of wood fuel includes a vertical feed combustion chamber (15) for receiving and supporting wood fuel in a vertical attitude or stack. A major upper portion of the combustion chamber column comprises a water jacket (14) for coupling to a source of water or heat transfer fluid for convection circulation of the fluid. The locus (31) of wood fuel combustion is thereby confined to the refractory base of the combustion chamber. A flue gas propagation delay channel (34) extending laterally from the base of the chamber affords delayed travel time in a high temperature refractory environment sufficient to assure substantially complete combustion of the gaseous products of wood burning with forced air prior to extraction of heat in heat exchanger (16). Induced draft draws the fuel gas and air mixture laterally through the combustion chamber and refractory high temperature zone to the heat exchanger and flue. Also included are active sources of forced air and induced draft, multiple circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.

Wood pellet market and trade: a global perspective  

SciTech Connect

This perspective provides an overview of wood pellet markets in a number of countries of high significance, together with an inventory of market factors and relevant past or existing policies. In 2010, the estimated global wood pellet production and consumption were close to 14.3 Mt (million metric tonnes) and 13.5 Mt, respectively, while the global installed production capacity had reached over 28 Mt. Two types of pellets are mainly traded (i) for residential heating and (ii) for large-scale district heating or co-fi ring installations. The EU was the primary market, responsible for nearly 61% and 85% of global production and consumption, respectively in 2010. EU markets were divided according to end use: (i) residential and district heating, (ii) power plants driven market, (iii) mixed market, and (iv) export-driven countries. North America basically serves as an exporter, but also with signifi cant domestic consumption in USA. East Asia is predicted to become the second-largest consumer after the EU in the near future. The development perspective in Latin America remains unclear. Five factors that determine the market characteristics are: (i) the existence of coal-based power plants, (ii) the development of heating systems, (iii) feedstock availability, (iv) interactions with wood industry, and (v) logistics factor. Furthermore, intervention policies play a pivotal role in market development. The perspective of wood pellets industry was also analyzed from four major aspects: (i) supply potential, (ii) logistics issues, (iii) sustainability considerations, and (iv) technology development.

Environmental Impacts of Preservative-Treated Wood Conference  

E-Print Network (OSTI)

This article was written and prepared by U.S. Government employees on official time, For decades chromated copper arsenate (CCA) was the primary preservative for treated wood used in residential construction. However, recent label changes submitted by CCA registrants will withdraw CCA from most residential applications. This action has increased interest in arsenic-free preservative systems that have been standardized by the American Wood Preservers ’ Association. These include acid copper chromate (ACC), alkaline copper quat (ACQ), copper azole (CBA-A and CA-B), copper citrate (CC), copper dimethyldithiocarbamate (CDDC), and copper HDO (CX-A). All of these CCA alternatives rely on copper as their primary biocide, although some have co-biocides to help prevent attack by copper-tolerant fungi. They have appearance and handling properties similar to CCA and are likely to be readily accepted by consumers. Prior studies indicate that these CCA alternatives release preservative components into the environment at a rate greater than or equal to that of CCA, but because these components have lower mammalian toxicity they are less likely to cause concern in residential applications. As the treated wood industry evolves it is probable that a wider range of types and retentions of wood preservatives will become available, with the treatment more closely tailored to a specific type of construction application.

Vitrification of NAC process residue  

Science Conference Proceedings (OSTI)

Vitrification tests have been performed with simulated waste compositions formulated to represent the residue which would be obtained from the treatment of low-level, nitrate wastes from Hanford and Oak Ridge by the nitrate to ammonia and ceramic (NAC) process. The tests were designed to demonstrate the feasibility of vitrifying NAC residue and to quantify the impact of the NAC process on the volume of vitrified waste. The residue from NAC treatment of low-level nitrate wastes consists primarily of oxides of aluminum and sodium. High alumina glasses were formulated to maximize the waste loading of the NAC product. Transparent glasses with up to 35 wt% alumina, and even higher contents in opaque glasses, were obtained at melting temperatures of 1200{degrees}C to 1400{degrees}C. A modified TCLP leach test showed the high alumina glasses to have good chemical durability, leaching significantly less than either the ARM-1 or the DWPF-EA high-level waste reference glasses. A significant increase in the final waste volume would be a major result of the NAC process on LLW vitrification. For Hanford wastes, NAC-treatment of nitrate wastes followed by vitrification of the residue will increase the final volume of vitrified waste by 50% to 90%; for Melton Valley waste from Oak Ridge, the increase in final glass volume will be 260% to 280%. The increase in volume is relative to direct vitrification of the waste in a 20 wt% Na{sub 2}O glass formulation. The increase in waste volume directly affects not only disposal costs, but also operating and/or capital costs. Larger plant size, longer operating time, and additional energy and additive costs are direct results of increases in waste volume. Such increases may be balanced by beneficial impacts on the vitrification process; however, those effects are outside the scope of this report.

Development of polypropylene/wood flour ecocomposites. Evaluation of silane as coupling agent  

SciTech Connect

The effects of Pinus Sylvestris wood flour as filler in polypropylene matrix was evaluated. The mechanical properties and the morphology of different wood flour/polypropylene composites (WPC) were studied. The composites materials were prepared with several amounts of wood flour from 10 to 30% wt. Mechanical properties show that the wood flour incorporation increases the rigidity of the composites. Morphological analysis indicates that agglomerates are formed, with amounts exceeding 30% of wood flour. For the silane--treated composites, the dispersion of the filler into the polypropylene (PP) matrix improved. Shore D hardness of the composites is decreased with the addition of the coupling agent.

Technical and economic review of wood energy systems for military bases  

DOE Green Energy (OSTI)

This report combines two reports dealing with industrial-sized wood combustion technology. As part of its industrial wood combustion effort, SERI's former Industrial Applications and Analysis Branch (IAAB) contracted with the Air Force through the Department of Energy (DOE) to review wood fuels and equipment and to perform an economic sensitivity analysis of small-scale industrial-sized wood combustion investments that might be considered for steam and/or electricity generation at Air Force Bases. Additionally, in 1979, SERI's IAAB contracted with North Carolina State University to produce the Decision Makers' Guide to Wood Fuel for Small Industrial Energy Use. These two reports have been combined to provide the Air Force with a comprehensive guide to wood energy combustion. Discussion is presented under the headings: comparison of wood fuels with conventional boiler fuels; densified biomass; fuel storage; fuel handling and preparation; wood-fired equipment; gasification of wood; retrofitting fossil-fuel boilers; cogeneration; pollution abatement; wood energy system economics and procurement of wood fuels.

SOLID PHASE MICROEXTRACTION SAMPLING OF FIRE DEBRIS RESIDUES IN THE PRESENCE OF RADIONUCLIDE SURROGATE METALS  

DOE Green Energy (OSTI)

The Federal Bureau of Investigation (FBI) Laboratory currently does not have on site facilities for handling radioactive evidentiary materials and there are no established FBI methods or procedures for decontaminating highly radioactive fire debris (FD) evidence while maintaining evidentiary value. One experimental method for the isolation of FD residue from radionuclide metals involves using solid phase microextraction (SPME) fibers to remove the residues of interest. Due to their high affinity for organics, SPME fibers should have little affinity for most (radioactive) metals. The focus of this research was to develop an examination protocol that was applicable to safe work in facilities where high radiation doses are shielded from the workers (as in radioactive shielded cells or ''hot cells''). We also examined the affinity of stable radionuclide surrogate metals (Co, Ir, Re, Ni, Ba, Cs, Nb, Zr and Nd) for sorption by the SPME fibers. This was done under exposure conditions that favor the uptake of FD residues under conditions that will provide little contact between the SPME and the FD material (such as charred carpet or wood that contains commonly-used accelerants). Our results from mass spectrometric analyses indicate that SPME fibers show promise for use in the room temperature head space uptake of organic FD residue (namely, diesel fuel oil, kerosene, gasoline and paint thinner) with subsequent analysis by gas chromatography (GC) with mass spectrometric (MS) detection. No inorganic forms of ignitable fluids were included in this study.

URBAN WOOD/COAL CO-FIRING IN THE NIOSH BOILER PLANT  

DOE Green Energy (OSTI)

Phase I of this project began by obtaining R&D variances for permits at the NIOSH boilerplant (NBP), Emery Tree Service (ETS) and the J. A. Rutter Company (JARC) for their portions of the project. Wood for the test burn was obtained from the JARC inventory (pallets), Thompson Properties and Seven D Corporation (construction wood), and the Arlington Heights Housing Project (demolition wood). The wood was ground at ETS and JARC, delivered to the Three Rivers Terminal and blended with coal. Three one-day tests using wood/coal blends of 33% wood by volume (both construction wood and demolition wood) were conducted at the NBP. Blends using hammermilled wood were operationally successful. Emissions of SO{sub 2} and NOx decreased and that of CO increased when compared with combusting coal alone. Mercury emissions were measured and evaluated. During the first year of Phase II the principal work focused upon searching for a replacement boilerplant and developing a commercial supply of demolition wood. The NBP withdrew from the project and a search began for another stoker boilerplant in Pennsylvania to replace it on the project. Three potential commercial demolition wood providers were contacted. Two were not be able to supply wood. At the end of the first year of Phase II, discussions were continuing with the third one, a commercial demolition wood provider from northern New Jersey. During the two-and-a-third years of the contract extension it was determined that the demolition wood from northern New Jersey was impractical for use in Pittsburgh, in another power plant in central New Jersey, and in a new wood gasifier being planned in Philadelphia. However, the project team did identify sufficient wood from other sources for the gasifier project. The Principal Investigator of this project assisted a feasibility study of wood gasification in Clarion County, Pennsylvania. As a result of the study, an independent power producer in the county has initiated a small wood gasification project at its site. Throughout much of this total project the Principal Investigator has counseled two small businesses in developing a waxed cardboard pellet business. A recent test burn of this biofuel appears successful and a purchase contract is anticipated soon. During the past two months a major tree-trimming firm has shown an active interest in entering the wood-chip fuel market in the Pittsburgh area and has contacted the NBP, among others, as potential customers. The NBP superintendent is currently in discussion with the facilities management of the Bruceton Research Center about resuming their interest in cofiring this renewable fuel to the stoker there.

Predicting Agricultural Management Influence on Long-Term Soil Organic Carbon Dynamics: Implications for Biofuel Production  

SciTech Connect

Long-term field experiments (LTE) are ideal for predicting the influence of agricultural management on soil organic carbon (SOC) dynamics and examining biofuel crop residue removal policy questions. Our objectives were (i) to simulate SOC dynamics in LTE soils under various climates, crop rotations, fertilizer or organic amendments, and crop residue managements using the CQESTR model and (ii) to predict the potential of no-tillage (NT) management to maintain SOC stocks while removing crop residue. Classical LTEs at Champaign, IL (1876), Columbia, MO (1888), Lethbridge, AB (1911), Breton, AB (1930), and Pendleton, OR (1931) were selected for their documented history of management practice and periodic soil organic matter (SOM) measurements. Management practices ranged from monoculture to 2- or 3-yr crop rotations, manure, no fertilizer or fertilizer additions, and crop residue returned, burned, or harvested. Measured and CQESTR predicted SOC stocks under diverse agronomic practices, mean annual temperature (2.1 19 C), precipitation (402 973 mm), and SOC (5.89 33.58 g SOC kg 1) at the LTE sites were significantly related (r 2 = 0.94, n = 186, P < 0.0001) with a slope not significantly different than 1. The simulation results indicated that the quantities of crop residue that can be sustainably harvested without jeopardizing SOC stocks were influenced by initial SOC stocks, crop rotation intensity, tillage practices, crop yield, and climate. Manure or a cover crop/intensified crop rotation under NT are options to mitigate loss of crop residue C, as using fertilizer alone is insufficient to overcome residue removal impact on SOC stocks

RESIDUAL STRESSES IN 3013 CONTAINERS  

SciTech Connect

The DOE Complex is packaging plutonium-bearing materials for storage and eventual disposition or disposal. The materials are handled according to the DOE-STD-3013 which outlines general requirements for stabilization, packaging and long-term storage. The storage vessels for the plutonium-bearing materials are termed 3013 containers. Stress corrosion cracking has been identified as a potential container degradation mode and this work determined that the residual stresses in the containers are sufficient to support such cracking. Sections of the 3013 outer, inner, and convenience containers, in both the as-fabricated condition and the closure welded condition, were evaluated per ASTM standard G-36. The standard requires exposure to a boiling magnesium chloride solution, which is an aggressive testing solution. Tests in a less aggressive 40% calcium chloride solution were also conducted. These tests were used to reveal the relative stress corrosion cracking susceptibility of the as fabricated 3013 containers. Significant cracking was observed in all containers in areas near welds and transitions in the container diameter. Stress corrosion cracks developed in both the lid and the body of gas tungsten arc welded and laser closure welded containers. The development of stress corrosion cracks in the as-fabricated and in the closure welded container samples demonstrates that the residual stresses in the 3013 containers are sufficient to support stress corrosion cracking if the environmental conditions inside the containers do not preclude the cracking process.

Particulate matter emissions from combustion of wood in district heating applications  

Science Conference Proceedings (OSTI)

The utilization of wood biomass to generate district heat and power in communities that have access to this energy source is increasing. In this paper the effect of wood fuel properties, combustion condition, and flue gas cleaning system on variation in the amount and formation of particles in the flue gas of typical district heating wood boilers are discussed based on the literature survey. Direct measurements of particulate matter (PM) emissions from wood boilers with district heating applications are reviewed and presented. Finally, recommendations are given regarding the selection of wood fuel, combustion system condition, and flue gas cleaning system in district heating systems in order to meet stringent air quality standards. It is concluded that utilization of high quality wood fuel, such as wood pellets produced from natural, uncontaminated stem wood, would generate the least PM emissions compared to other wood fuel types. Particulate matter emissions from grate burners equipped with electrostatic precipitators when using wood pellets can be well below stringent regulatory emission limit such as particulate emission limit of Metro Vancouver, Canada.

Low VOC drying of lumber and wood panel products. Progress report No. 7  

DOE Green Energy (OSTI)

Green pine blocks (2x1x 1) were dried to different moisture levels at 120 degrees C. They were immersed in D{sub 2}O (greater than 99% isotopic Content) for different periods at room temperature, and were then cut in halves. One piece from each set was then wrapped in plastic, and microwaved at 110 W, for 30 minutes, with the field being cycled to keep the wood surface at 90-100 degrees C. Fibers taken from just inside the wet surface from five regions along the length of the piece were then analysed by mass spectrometry with a direct insertion probe. The m/e profiles of the three isotopic forms of water, namely H{sub 2}O, HOD, and D{sub 2}O, remained unchanged as the wood was heated inside the spectrometer, indicating that they were bound equally strongly to the wood. The water released from the green wood had the same isotopic composition regardless of whether or not the wood was microwaved (Table 1), indicating that the exchangeable protons in wood were not affected by microwaving. However, as the wood progressively dried, the water released from the microwaved wood was of lower isotopic content, which means that microwaving increases access of the exchangeable protons in wood tissue to water. The only exchangeable protons in dried wood are those sited on hydroxyl groups, and the difference in isotopic exchange is the greatest for dried wood. This must mean that as wood dries, internal hydrogen bonding restricts access of D{sub 2}O to the hydroxyl protons. Presumably the energy transferred to water upon microwaving is sufficient to at least partially overcome this barrier. The effect is akin to the hysteresis that occurs for moisture sorption to green and dried wood. Similar isotope exchange work with D{sub 2}O has been previously conducted to determine the accessibility of cellulose to water.

The morphological development of a wood burl shader  

E-Print Network (OSTI)

In the field of computer graphics, shaders provide an interface between lights and surfaces, giving the appearance of metal, plastic, wood, etc. As the field progresses, more and more shaders are required to simulate a wider and wider variety of materials. We present a new shader for the simulation of wood burl, a complex material used in furniture, art, car interiors, and a host of other luxury items. This shader was developed through a morphological approach - a study of the original material, its structure, and growth. Consequently, research began with a thorough look at wood burl, polished and unpolished, in an assortment of different species. We discovered the appearance can be broken into three sub-appearances - knots, curl, and a subtle undergrain. These three sub-appearances interact to create the characteristic swirls and whorls of burl. For the subtle undergrain, we used a common oak shader, added noise, and faded it into the background. We then developed a system of randomly placing points through the material to act as knots. Since the knots grow and distort the surrounding grain, we used distance-scaled forces to push the surface coordinates around and between all the knots. When the oak shader is applied, it appears to swirl and curl around the knots, much like a stream between rocks. This created the first level of curl or swirly grained wood, but one level alone appeared flat. To solve this, we procedurally blended levels of curl to give a look of increased depth. Finally, we added reflection, gloss, and other surface properties to give a look of warmth and polish. All of these properties are controlled by a set of parameters in the shader's interface. By adjusting these parameters, the user can emulate a variety of different burl types.

Quality of Wood Pellets Produced in British Columbia for Export  

Science Conference Proceedings (OSTI)

Wood pellet production and its use for heat and power production are increasing worldwide. The quality of export pellets has to consistently meet certain specifications as stipulated by the larger buyers, such as power utilities or as specified by the standards used for the non-industrial bag market. No specific data is available regarding the quality of export pellets to Europe. To develop a set of baseline data, wood pellets were sampled at an export terminal in Vancouver, British Columbia, Canada. The sampling period was 18 months in 2007-2008 when pellets were transferred from storage bins to the ocean vessels. The sampling frequency was once every 1.5 to 2 months for a total of 9 loading/shipping events. The physical properties of the wood pellets measured were moisture content in the range of 3.5% to 6.5%, bulk density from 728 to 808 kg/m3, durability from 97% to 99%, fines content from 0.03% to 0.87%, calorific value as is from 17 to almost 18 MJ/kg, and ash content from 0.26% to 0.93%.The diameter and length were in the range of 6.4 to 6.5 mm and 14.0 to 19.0 mm, respectively. All of these values met the published non-industrial European grades (CEN) and the grades specified by the Pellet Fuel Institute for the United States for the bag market. The measured values for wood pellet properties were consistent except the ash content values decreased over the test period.

Tectonic Setting of the Wooded Island Earthquake Swarm, Eastern Washington  

SciTech Connect

Magnetic anomalies provide insights into the tectonic implications of a swarm of ?1500 shallow (?1 km deep) earthquakes that occurred in 2009 on the Hanford site,Washington. Epicenters were concentrated in a 2 km2 area nearWooded Island in the Columbia River. The largest earthquake (M 3.0) had first motions consistent with slip on a northwest-striking reverse fault. The swarm was accompanied by 35 mm of vertical surface deformation, seen in satellite interferometry (InSAR), interpreted to be caused by ?50 mm of slip on a northwest-striking reverse fault and associated bedding-plane fault in the underlying Columbia River Basalt Group (CRBG). A magnetic anomaly over exposed CRBG at Yakima Ridge 40 km northwest of Wooded Island extends southeastward beyond the ridge to the Columbia River, suggesting that the Yakima Ridge anticline and its associated thrust fault extend southeastward in the subsurface. In map view, the concealed anticline passes through the earthquake swarm and lies parallel to reverse faults determined from first motions and InSAR data. A forward model of the magnetic anomaly near Wooded Island is consistent with uplift of concealed CRBG, with the top surface <200 m below the surface. The earthquake swarm and the thrust and bedding-plane faults modeled from interferometry all fall within the northeastern limb of the faulted anticline. Although fluids may be responsible for triggering the Wooded Island earthquake swarm, the seismic and aseismic deformation are consistent with regional-scale tectonic compression across the concealed Yakima Ridge anticline.

Hydrothermal systems of the Wood River District, central Idaho, have been studied by geologic mapping of thermal spring areas and geochemical investigations of thermal and non-thermal waters. This report summarizes the new geochemical data gathered during the study. Integration of the results of geological and geochemical studies has led to development of a target model for hydrothermal resources on the margin of the Idaho Batholith. Warfield Hot Springs, with temperatures up to 58/sup 0/C, flow from a major shear zone along the margin of an apophysis of the batholith. Hailey Hot Springs, with temperatures up to 60/sup 0/C, occur in an area of multiple thrust faults and newly recognized, closely spaced normal faults in the Paleozoic Milligen and Wood River Formations, 2.5 km from a highly brecciated batholith contact. Other Wood River district hydrothermal systems also occur along the margins of batholith apophyses or in adjacent highly fractured Paleozoic rocks, where there are indications of batholith rocks at shallow depths (100 to 300 m) in water wells.

Long-term lime pretreatment of poplar wood  

E-Print Network (OSTI)

Lignocellulosic biomass (e.g., poplar wood) provides a unique and sustainable resource for environmentally safe organic fuels and chemicals. The core of this study is the pretreatment step involved in bioconversion processes. Pretreatment is required to realize high yields vital to commercial success. The focus of the pretreatment step is to methodically change key features of the biomass to favor enzymatic hydrolysis. This work assesses the compositional changes due to oxidative and non-oxidative longterm lime pretreatment of poplar wood (up to 4 weeks of pretreatment) at mild temperatures (25ºC to 65ºC), and their effect on the enzymatic yield of glucan and xylan. The most important pretreatment yield of lignin was 54 g lignin remaining/100 g lignin in raw biomass, and was accomplished for 4-week lime pretreatment at 65ºC in oxidative conditions. The corresponding pretreatment yields of glucan and xylan were 85.9 g glucan recovered/100 g glucan in raw biomass and 80.2 g xylan recovered/100 g xylan in raw biomass respectively. For poplar wood oxidatively pretreated with lime for 4 weeks at 65ºC and enzymatically hydrolyzed with an enzyme loading of 15 FPU/g glucan in raw biomass during a 3-day period, the best overall yields of glucan and xylan, were 80.7 g glucan hydrolyzed/100 g glucan in raw biomass and 66.9 g xylan hydrolyzed/100 g xylan in raw biomass respectively. The corresponding hydrolysis yields were 94.0 g glucan hydrolyzed/100 g glucan in treated biomass and 83.5 g xylan hydrolyzed/100 g xylan in treated biomass respectively. Because there is a previous study of long-term lime pretreatment of corn stover (Kim, 2004), the data obtained in this work show the effect of using woody lignocellulose as substrate. From the comparison, resulted that in the case of poplar wood oxidatively pretreated at 65ºC for 4 weeks, less lignin was removed and more carbohydrates were solubilized, however the hydrolysis yield of glucan was almost equal and the hydrolysis yield of xylan was higher than the reported by Kim for corn stover oxidatively pretreated at 55ºC for 4 weeks. The overall yield of glucan resulted lower in the case of poplar wood because of the lower pretreatment yield of glucan. Thus, it is important to complete the mass balances including an analysis on the pretreatment liquor to determine if the solubilized glucan was degraded.

Shell-armored wood cobbles as a potential criterion for detrital coal deposits  

Science Conference Proceedings (OSTI)

Shell-armored wood cobbles occur on detrital-peat beaches along the seaward edge of the Mississippi Delta. Shell material consists exclusively of Mulinia lateralis, a dwarf surf clam. Soft, heavy, waterlogged wood fragments are abraded and become armored by hard shells in response to wave activity on the beach. Although their preservation potential is suspect, fossilized shell-armored wood clasts would probably be recognized as a type of coal ball and might indicate an allochthonous origin for the host coal.

Rapid determination of wood fuel moisture content using a microwave oven for drying  

SciTech Connect

A method of determining moisture content (MC) of wood fuel using a microwave oven for drying the wood was evaluated by drying paired samples of five different wood fuel types in a microwave oven and a conventional oven. When compared to the conventional oven drying method, the microwave technique produces consistently lower MC determinations, although the differences are less than 1 percent. The advantage of the microwave technique is the speed at which MC determinations can be determined (less than 15 minutes). Schedules for drying five wood fuel types are presented. (Refs. 7).

Riparian forest disturbances by a mountain flood -- the influence of floated wood  

E-Print Network (OSTI)

Large floods can have major impacts on riparian forests. Here we examine the variability and spatial distribution of riparian forest responses along eight third- to fifth-order streams following a large flood ( 100 year recurrence interval) in the Cascade Mountain Range of Oregon. We categorized disturbance intensity (physical force) exerted on riparian trees during floods into three classes: (i) purely fluvial (high water flow only); (ii) ¯uvial supplemented by dispersed pieces of floating wood (uncongested wood transport); (iii) fluvial with movement of batches of wood (congested wood transport). These types of material transport and associated classes of disturbance intensity resulted in a gradient of biotic responses of disturbance severity ranging from standing riparian trees inundated by high water, to trees toppled but still partially rooted, to complete removal of trees. High within-stream and among stream responses were inflenced by pre-flood stream and riparian conditions as well as flood dynamics, especially the availability of individual pieces or congested batches of wood. Fluvial disturbance alone toppled fewer riparian trees than in reaches where floodwaters transported substantial amounts of wood. Debris flows delivered additional wood and sediment to parts of reaches of four of these study streams; riparian trees were removed and toppled for up to 1 5 km downstream of the debris flow tributary channel. Congested wood transport resulted in higher frequency of toppled trees and greater deposition of new wood levees along channel margins. The condition of the landscape at the time of a major ¯ood strongly influenced

A Benchmark Study on Casting Residual Stress  

Science Conference Proceedings (OSTI)

Stringent regulatory requirements, such as Tier IV norms, have pushed the cast iron for automotive applications to its limit. The castings need to be designed with closer tolerances by incorporating hitherto unknowns, such as residual stresses arising due to thermal gradients, phase and microstructural changes during solidification phenomenon. Residual stresses were earlier neglected in the casting designs by incorporating large factors of safety. Experimental measurement of residual stress in a casting through neutron or X-ray diffraction, sectioning or hole drilling, magnetic, electric or photoelastic measurements is very difficult and time consuming exercise. A detailed multi-physics model, incorporating thermo-mechanical and phase transformation phenomenon, provides an attractive alternative to assess the residual stresses generated during casting. However, before relying on the simulation methodology, it is important to rigorously validate the prediction capability by comparing it to experimental measurements. In the present work, a benchmark study was undertaken for casting residual stress measurements through neutron diffraction, which was subsequently used to validate the accuracy of simulation prediction. The stress lattice specimen geometry was designed such that subsequent castings would generate adequate residual stresses during solidification and cooling, without any cracks. The residual stresses in the cast specimen were measured using neutron diffraction. Considering the difficulty in accessing the neutron diffraction facility, these measurements can be considered as benchmark for casting simulation validations. Simulations were performed using the identical specimen geometry and casting conditions for predictions of residual stresses. The simulation predictions were found to agree well with the experimentally measured residual stresses. The experimentally validated model can be subsequently used to predict residual stresses in different cast components. This enables incorporation of the residual stresses at the design phase along with external loads for accurate predictions of fatigue and fracture performance of the cast components.

Solar Photovoltaics for Sustainable Agriculture and  

E-Print Network (OSTI)

Solar photovoltaic (PV) systems have shown their potential in rural electrification projects around the world, especially concerning Solar Home Systems. With continuing price decreases of PV systems, other applications are becoming economically attractive and growing experience is gained with the use of PV in such areas as social and communal services, agriculture and other productive activities, which can have a significant impact on rural development. There is still a lack of information, however, on the potential and limitations of such PV applications. The main aim of this study is, therefore, to contribute to a better understanding of the potential impact and of the limitations of PV systems on sustainable agriculture and rural development (SARD), especially concerning income-generating activities. It is, in fact, of paramount importance to identify the potential contribution of PV to rural development in order to gain further financial and political commitment for PV projects and programmes and to design appropriate PV projects. One of the main lessons learnt through this study is that success of PV programmes is significantly enhanced when an integrated strategy is followed. Solar photovoltaic systems, through their flexibility in use, offer unique chances for the energy sector to provide “packages ” of energy services to remote rural areas such as for rural health care, education, communication, agriculture, lighting and water supply. It is hoped that this document contributes to the generation of ideas and discussions among the different institutions involved in providing these services to rural areas and thereby to an "informed " decision on the PV technology option.

A preliminary assessment of the state of harvest and collection technology for forest residues  

DOE Green Energy (OSTI)

To meet the 'Twenty in Ten Initiative' goals set in the 2007 State of the Union address, forest resources will be needed as feedstocks for lignocellulosic ethanol production. It has been estimated that 368 million dry tons can be produced annually in the U.S. from logging residues and fuel treatment thinnings. Currently, very little of this woody biomass is used for energy production due to the costs and difficulty in collecting and transporting this material. However, minimizing biomass costs (including harvest, handling, transport, storage, and processing costs) delivered to the refinery is necessary to develop a sustainable cellulosic ethanol industry. Achieving this goal requires a fresh look at conventional timber harvesting operations to identify ways of efficiently integrating energy wood collection and developing cost-effective technologies to harvest small-diameter trees. In conventional whole-tree logging operations, entire trees are felled and skidded from the stump to the landing. The residues (also called slash), consisting of tops and limbs, accumulate at the landing when trees are delimbed. This slash can be ground at the landing with a mobile grinder or transported to another central location with a stationary grinder. The ground material is transported via chip vans, or possibly large roll on/off containers, to the user facility. Cut-to-length harvesting systems are gaining popularity in some locations. In these operations, specialized harvesters that can fall, delimb, and cut logs to length are used. The small diameter tops and limbs accumulate along the machine's track. It can be left in the forest to dry or removed soon after harvest while logs are extracted. Removing slash during the same operation as the wood has been shown to be more efficient. However, leaving residue in the forest to dry reduces moisture content, which improves grinder performance, reduces dry matter loss during storage, and inhibits colonization of fungi that produce harmful spores. In recent years, new machines that are specially designed for collection of small diameter wood have been developed in the U.S. and Europe. Residue bundlers and balers improve transportation and handling efficiency by densifying the material and packaging it so that it can be handled with conventional equipment. An experimental integrated harvester/grinder can fall small diameter trees and feed them into a grinder. The ground material is collected in a bin that can be dumped into a chip van. The harvester head is also capable of delimbing and bucking (cut into sections) small timber to be used for pulp and posts. Limitations of these new technologies are their large capital costs and complexity, leading to high maintenance costs and the need for highly trained operators. To ensure that quality feedstock materials consistently enter the mouth of the refinery, the uniform format supply system concept proposes that feedstock diversity be managed at harvest, much like the current grain supply system. This allows for standardization of key infrastructure components and facilitation of a biomass commodity system. Challenges in achieving a uniform woody biomass supply include, but are not limited to, developing machines for efficient harvest of small-diameter trees in a range of topographies and conditions, developing machines and operating plans for grinding biomass as near to the stump as possible, developing cost-effective drying strategies to reduce losses and mold growth during wood chip storage, and quantifying environmental impacts of slash removal and fuel thinnings to aid landowner decisions and policy development.

Transcriptome and Biochemical Analyses of Fungal Degradation of Wood  

SciTech Connect

Lignocellulosic accounts for a large percentage of material that can be utilized for biofuels. The most costly part of lignocellulosic material processing is the initial hydrolysis of the wood which is needed to circumvent the lignin barrier and the crystallinity of cellulose. Enzymes will play an increased role in this conversion in that they potentially provide an alternative to costly and caustic high temperature and acid treatment. The increasing use of enzymes in biotechnology is facilitated by both continued improvements in enzyme technology but also in the discovery of new and novel enzymes. The present proposal is aimed at identifying the enzymes which are known to depolymerize woody biomass. Fundamental understanding of how nature gains access to cellulose and hemicellulose will impact all applications. Because fungi are the only known microbes capable of circumventing the lignin barrier, knowledge of the enzyme they use is of great potential for biofuel processing. Nature has evolved different fungal mechanisms for enzymatic hydrolysis of wood. Most notable are the white-rot fungi (wrf) and the brown-rot fungi (brf). This proposed research aims at determining the complete transcriptome of three wrf and two brf to determine the enzymes involved in lignocellulose degradation. The transcriptome work will be supported by enzyme characterization (and zymograms) and finally analysis of the lignin component to determine the mode of lignin modification. In this proposed research, we hypothesize that: 1) Determination of the complete transcriptome of closely related white and brown rot fungi will lead to knowledge of the relevant enzymes involved in wood degradation. 2) Knowledge of the extracellular transcriptome and the mechanism of wood decay can only be obtained if the products of the decay are known. As such, characterization of the lignin oxidation products will correlate the enzymes involved (obtained from the transcriptome) to the lignin oxidation products. The Department of Energy has sequenced the P. chrysosporium genome and has approved the sequencing of the genome of the closely-related brown rot fungus P. placenta. This comparative genomics approach will yield important information on differences between these two fungi. Analysis of gene unique to each fungus (which have been lost or gained) can potentially lead to determining the enzymes which are responsible for each type of decay. This comparison, however, would not be complete without comparing the transcriptome and the proteome/enzymes. Comparative genomics may tell us which genes may be important, but it will not tell us when these genes are expressed, at what levels and will not necessarily tell us what these genes do.

Making Steel Framing as Thermally Efficient as Wood  

E-Print Network (OSTI)

In many world regions like North America and Scandinavia wood framing is dominant technology for residential buildings. During last two decades several companies around the world started to promote a low-gage steel framing for residential and commercial buildings. Steel framing has many advantages over wood framing; strength, low weight, dimensional stability, resistance to termite damage, almost 100% recycleability, etc .. However because of several reasons an application of steel as a framing material in US residential building market is relatively low. Steel industry has noticed much more success on commercial building market which is not as rigorous regarding thermal efficiency and energy conservation. Steel framing has one significant disadvantage over wood; Steel members conduct heat extremely well. This effect is known as thermal bridging, and it can sharply reduce a wall's effective Rvalue. The simplest and most common way to overcome this problem is to block the path of heat flow with rigid foam insulation. Adding rigid foam insulation not only increases the whole wall's R-value, but it also reduces the temperature difference between the center of the cavity and the stud area, which cuts down on the possibility of black stains forming from dirt getting asymmetrically attracted to cold spots on a wall's surface. However, rigid foam insulation is an expensive solution. Several material configurations were developed in the past to increase thermal effectiveness of steel-framed structures. This paper is focused on most common options of thermal improvements of steels framed walls. They were as follow: 1) diminishing the contact area between the studs and exterior sheathing materials, 2) reducing the steel stud web area, 3) replacing the steel web with a less conductive material, and 4) placing foam insulation in locations where the thermal shorts are most critical. Researchers at Oak Ridge National Laboratory (ORNL) have utilized both hot box testing and computer simulations in aim to optimize thermal design of steel stud walls.. While examining several material options, ORNL's BTC was also striving to develop energy-efficient steel stud wall technologies that would enable steel-stud walls to beat the performance of traditional 2 x 6 wood stud walls. Several, most current, ORNL developments in steel framing are presented below.

Process for treatment of residual gas  

SciTech Connect

A process is disclosed for the treatment of the residual gases which are produced when hydrogen sulfide is reduced, by combustion, to elementary sulfur by the Claus process. The residual gases are fed through a heated conduit and gas scrubber, wherein the temperature of those residual gases are maintained above the melting point of sulfur. A portion of the raw coke oven gas condensate is admitted to the gas scrubber to be returned to the coke oven battery main from the flushing liquid separator as flushing liquor. The residual gases are then conducted through the coke oven gas purification process equipment along with the raw coke oven gas where the residual gases are intermixed with the raw coke oven gas prior to tar separation.

Three Essays on U.S. Agriculture under Climate Change: Active Engagement in Mitigation and Adaptation  

E-Print Network (OSTI)

This dissertation investigates: (1) the implications of including high-yielding energy sorghum under the Renewable Fuels Standard (RFS2) program; (2) the effects of RFS2 with and without projected climate change scenarios on U.S. agriculture; (3) the spatial distribution of cattle breeders in Texas to quantify how climate factors influence cattle breed selection. In the RFS2 energy sorghum work, the ability of the agriculture sector to meet the fuel requirements of RFS2 is examined with and without energy sorghum being a possibility using an agricultural sector model. The results show that energy sorghum would be a valuable contributor that would be used as a feedstock producing over 13 billion gallons per year of cellulosic ethanol. Without the presence of energy sorghum it is found that switchgrass serves as the major cellulosic ethanol feedstock. Findings also indicate that the presence of high-yielding energy sorghum does relax commodity prices and export reductions except for grain sorghum as energy sorghum competes with grain sorghum production. In addition, the results show that the introduction of energy sorghum has minimal effects on GHG mitigation potential in the agricultural sector. In the RFS2 and climate change research, the analysis shows that climate change eases the burden of meeting the RFS2 mandates increasing consumer welfare while decreasing producer welfare. The results also show that climate change encourages a more diversified use of biofuel feedstocks for cellulosic ethanol production, in particular crop residues. In the cattle breed research, summer heat stress is found to be a significant factor for breed selection: positive for Bos indicus and negative for Bos taurus and composite breeds. The estimation results also indicate a price-driven trade-off between Bos taurus and Bos indicus breeds.

THE ROLE OF DEAD WOOD IN MAINTAINING ARTHROPOD DIVERSITY ON THE FOREST FLOOR.  

Science Conference Proceedings (OSTI)

Abstract—Dead wood is a major component of forests and contributes to overall diversity, primarily by supporting insects that feed directly on or in it. Further, a variety of organisms benefit by feeding on those insects. What is not well known is how or whether dead wood influences the composition of the arthropod community that is not solely dependent on it as a food resource, or whether woody debris influences prey available to generalist predators. One group likely to be affected by dead wood is ground-dwelling arthropods. We studied the effect of adding large dead wood to unburned and frequently burned pine stands to determine if dead wood was used more when the litter and understory plant community are removed. We also studied the effect of annual removal of dead wood from large (10-ha) plots over a 5-year period on ground-dwelling arthropods. In related studies, we examined the relationships among an endangered woodpecker that forages for prey on live trees, its prey, and dead wood in the forest. The results of these and other studies show that dead wood can influence the abundance and diversity of the ground-dwelling arthropod community and of prey available to generalist predators not foraging directly on dead trees.

Relationships between dead wood and arthropods in the Southeastern United States.  

SciTech Connect

The importance of dead wood to maintaining forest diversity is now widely recognized. However, the habitat associations and sensitivities of many species associated with dead wood remain unknown, making it difficult to develop conservation plans for managed forests. The purpose of this research, conducted on the upper coastal plain of South Carolina, was to better understand the relationships between dead wood and arthropods in the southeastern United States. In a comparison of forest types, more beetle species emerged from logs collected in upland pine-dominated stands than in bottomland hardwood forests. This difference was most pronounced for Quercus nigra L., a species of tree uncommon in upland forests. In a comparison of wood postures, more beetle species emerged from logs than from snags, but a number of species appear to be dependent on snags including several canopy specialists. In a study of saproxylic beetle succession, species richness peaked within the first year of death and declined steadily thereafter. However, a number of species appear to be dependent on highly decayed logs, underscoring the importance of protecting wood at all stages of decay. In a study comparing litter-dwelling arthropod abundance at different distances from dead wood, arthropods were more abundant near dead wood than away from it. In another study, grounddwelling arthropods and saproxylic beetles were little affected by large-scale manipulations of dead wood in upland pine-dominated forests, possibly due to the suitability of the forests surrounding the plots.

URBAN WOOD/COAL CO-FIRING IN THE NIOSH BOILERPLANT  

DOE Green Energy (OSTI)

During the third quarter, the experimental portion of the project was carried out. Three one-day tests using wood/coal blends of 33% wood by volume (both construction wood and demolition wood) were conducted at the NIOSH Boiler Plant (NBP). Blends using hammer-milled wood were operationally successful and can form the basis of Phase II. Emissions of SO{sub 2} and NOx decreased and that of CO increased when compared with combusting coal alone. Mercury emissions were measured and the mathematical modeling of mercury speciation reactions continued, yielding many interesting results. Material and energy balances for the test periods at the NBP, as well as at the Bellefield Boiler Plant, were prepared. Steps were taken to remove severe constraints from the Pennsylvania Switchgrass Energy and Conservation Project and to organize the supplying of landfill gas to the Bruceton federal complex. Two presentations were made to meetings of the Electric Power Research Institute and the National Energy Technology Laboratory.

Radiological considerations of phosphogypsum utilization in agriculture  

Science Conference Proceedings (OSTI)

The radiological concerns associated with phosphogypsum utilization in agriculture have been placed in perspective by considering the consequences of a hypothetical case involving heavy long term applications of phosphogypsum. In California, such a schedule might consist of an initial gypsum application of 10 tons/acre followed by alternate year applications of 5 tons/acre. If the radium content of the gypsum were 15 pCi/g and the till depth 6 inches, this schedule could be maintained for more than 100 years before the radium buildup in the soil would reach a proposed federal concentration limit of 5 pCi/g. An agricultural worker spending 40 h a week in a field containing 5 pCi/g of radium would be exposed to terrestrial radiation of about 7 ..mu..R/h above background. This exposure would result in an annual radiation dose of about 15 mrem, which is 3% of the recommended limit for an individual working in an uncontrolled area. Five pCi/g of radium in the soil could generate airborne radon daughter concentrations exceeding the concentration limit proposed for residential exposure. However, as residential exposure limits are predicated on 75% of continuous occupancy, these limits should not be applied to agricultural workers because of the seasonal nature of their work. Radium uptake by food crops grown in the hypothetical soil would result in a 50 year integrated dose to the bone surface of 1.4 rem. This dose is conservatively based on the assumption that an adult's total vegetable diet comes from this source and that consumption was continuous during the 50 year period.

Utilization of agricultural wastes for production of ethanol. Progress report, October 1979-May 1980  

DOE Green Energy (OSTI)

The project proposes to develop methods to utilize agricultural wastes, especially cottonseed hulls and peanut shells to produce ethanol. Initial steps will involve development of methods to break down cellulose to a usable form of substrates for chemical or biological digestion. The process of ethanol production will consist of (a) preparatory step to separate fibrous (cellulose) and non-fibrous (non-cellulosic compounds). The non-cellulosic residues which may include grains, fats or other substrates for alcoholic fermentation. The fibrous residues will be first pre-treated to digest cellulose with acid, alkali, and sulfur dioxide gas or other solvents. (b) The altered cellulose will be digested by suitable micro-organisms and cellulose enzymes before alcoholic fermentation. The digester and fermentative unit will be specially designed to develop a prototype for pilot plant for a continuous process. The first phase of the project will be devoted toward screening of a suitable method for cellulose modification, separation of fibrous and non-fibrous residues, the micro-organism and enzyme preparations. Work is in progress on: the effects of various microorganisms on the degree of saccharification; the effects of higher concentrations of acids, alkali, and EDTA on efficiency of microbial degradation; and the effects of chemicals on enzymatic digestion.

Climate policy implications for agricultural water demand  

SciTech Connect

Energy, water and land are scarce resources, critical to humans. Developments in each affect the availability and cost of the others, and consequently human prosperity. Measures to limit greenhouse gas concentrations will inevitably exact dramatic changes on energy and land systems and in turn alter the character, magnitude and geographic distribution of human claims on water resources. We employ the Global Change Assessment Model (GCAM), an integrated assessment model to explore the interactions of energy, land and water systems in the context of alternative policies to limit climate change to three alternative levels: 2.5 Wm-2 (445 ppm CO2-e), 3.5 Wm-2 (535 ppm CO2-e) and 4.5 Wm-2 (645 ppm CO2-e). We explore the effects of two alternative land-use emissions mitigation policy options—one which taxes terrestrial carbon emissions equally with fossil fuel and industrial emissions, and an alternative which only taxes fossil fuel and industrial emissions but places no penalty on land-use change emissions. We find that increasing populations and economic growth could be anticipated to almost triple demand for water for agricultural systems across the century even in the absence of climate policy. In general policies to mitigate climate change increase agricultural demands for water still further, though the largest changes occur in the second half of the century, under both policy regimes. The two policies examined profoundly affected both the sources and magnitudes of the increase in irrigation water demands. The largest increases in agricultural irrigation water demand occurred in scenarios where only fossil fuel emissions were priced (but not land-use change emission) and were primarily driven by rapid expansion in bioenergy production. In these scenarios water demands were large relative to present-day total available water, calling into question whether it would be physically possible to produce the associated biomass energy. We explored the potential of improved water delivery and irrigation system efficiencies. These could potentially reduce demands substantially. However, overall demands remained high under our fossil-fuel-only tax policy. In contrast, when all carbon was priced, increases in agricultural water demands were smaller than under the fossil-fuel-only policy and were driven primarily by increased demands for water by non-biomass crops such as rice. Finally we estimate the geospatial pattern of water demands and find that regions such as China, India and other countries in south and east Asia might be expected to experience greatest increases in water demands.?

Agricultural scientists cut alcohol fuel costs  

Science Conference Proceedings (OSTI)

Scientists at the US Department of Agriculture have succeeded in lowering the cost of making alcohol from corn by 15 cents to $1.64 per gallon. The cost of drying distillers' solubles dropped because at the end of each cooking/fermenting/distilling run, the solubles are used for cooking, cooling and fermenting in the next run. One evaporation of solubles is required after 10 runs, so energy cost is cut from 17 cents to 1.7 cents. The protein by-products recovered, can be used as swine and poultry feeds and as human food.

Energy and US agriculture: 1974 and 1978  

SciTech Connect

Agricultural production used approximately 8.5 billion gallons of liquified fuel in 1978. This was up from the nearly 8 billion gallons in 1974. Fuel oil and liquified petroleum (LP) gas usage remained relatively constant between 1974 and 1978. The most dramatic changes were in diesel and gasoline usage. Gasoline use dropped about 0.2 billion gallons and diesel fuel use increased almost 0.7 billion gallons, accounting for the net 0.5 billion gallon increase in liquid fuel usage. On farm business use of natural gas and electricity showed virtually no change between 1974 and 1978.

Effect of sewage sludge content on gas quality and solid residues produced by cogasification in an updraft gasifier  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer Cogasification of sewage sludge with wood pellets in updraft gasifier was analysed. Black-Right-Pointing-Pointer The effects of sewage sludge content on the gasification process were examined. Black-Right-Pointing-Pointer Sewage sludge addition up to 30 wt.% reduces moderately the process performance. Black-Right-Pointing-Pointer At high sewage sludge content slagging and clinker formation occurred. Black-Right-Pointing-Pointer Solid residues produced resulted acceptable at landfills for non-hazardous waste. - Abstract: In the present work, the gasification with air of dehydrated sewage sludge (SS) with 20 wt.% moisture mixed with conventional woody biomass was investigated using a pilot fixed-bed updraft gasifier. Attention was focused on the effect of the SS content on the gasification performance and on the environmental impact of the process. The results showed that it is possible to co-gasify SS with wood pellets (WPs) in updraft fixed-bed gasification installations. However, at high content of sewage sludge the gasification process can become instable because of the very high ash content and low ash fusion temperatures of SS. At an equivalent ratio of 0.25, compared with wood pellets gasification, the addition of sewage sludge led to a reduction of gas yield in favor of an increase of condensate production with consequent cold gas efficiency decrease. Low concentrations of dioxins/furans and PAHs were measured in the gas produced by SS gasification, well below the limiting values for the exhaust gaseous emissions. NH{sub 3}, HCl and HF contents were very low because most of these compounds were retained in the wet scrubber systems. On the other hand, high H{sub 2}S levels were measured due to high sulfur content of SS. Heavy metals supplied with the feedstocks were mostly retained in gasification solid residues. The leachability tests performed according to European regulations showed that metals leachability was within the limits for landfilling inert residues. On the other hand, sulfate and chloride releases were found to comply with the limits for non-hazardous residues.

Illinois biomass resources: annual crops and residues; canning and food-processing wastes. Preliminary assessment  

DOE Green Energy (OSTI)

Illinois, a major agricultural and food-processing state, produces vast amounts of renewable plant material having potential for energy production. This biomass, in the form of annual crops, crop residues, and food-processing wastes, can be converted to alternative fuels (such as ethanol) and industrial chemicals (such as furfural, ethylene, and xylene). The present study provides a preliminary assessment of these Illinois biomass resources, including (a) an appraisal of the effects of their use on both agriculture and industry; (b) an analysis of biomass conversion systems; and (c) an environmental and economic evaluation of products that could be generated from biomass. It is estimated that, of the 39 x 10/sup 6/ tons of residues generated in 1978 in Illinois from seven main crops, about 85% was collectible. The thermal energy equivalent of this material is 658 x 10/sup 6/ Btu, or 0.66 quad. And by fermenting 10% of the corn grain grown in Illinois, some 323 million gallons of ethanol could have been produced in 1978. Another 3 million gallons of ethanol could have been produced in the same year from wastes generated by the state's food-processing establishments. Clearly, Illinois can strengthen its economy substantially by the development of industries that produce biomass-derived fuels and chemicals. In addition, a thorough evaluation should be made of the potential for using the state's less-exploitable land for the growing of additional biomass.
