With the cost of landfill disposal skyrocketing and land availability becoming scarce, better options are required for managing our nation`s biomass waste. In response to this need, the University of Tennessee Space Institute (UTSI) is evaluating an innovative idea (described as Chicken-Bio Nuggets Gasification process) to gasify waste products from the poultry industry and industrial wood/biomass-based residues in {open_quotes}as-is{close_quotes} or aggregate form. The presence of potassium salts in the poultry waste as well as in the biomass can act as a catalyst in reducing the severity of the thermal gasification. As a result, the mixture of these waste products can be gasified at a much lower temperature (1,300-1,400{degrees}F versus 1,800-2,000{degrees}F for conventional thermal gasification). Also, these potassium salts act as a catalyst by accelerating the gasification reaction and enhancing the mediation reaction. Hence, the product gas from this UTSI concept can be richer in methane and probably can be used as a source of fuel (to replace propane in hard reach remote places) or as a chemical feed stock. Exxon Research and Engineering Company has tested a similar catalytic gasification concept in a fluid-bed gasifier using coal in a one ton/day pilot plant in Baytown, Texas. If found technically and economically feasible, this concept can be later on extended to include other kinds of waste products such as cow manure and wastes from swine, etc.
