The economy of chip, whole-tree and short-wood methods in the pulpwood and fuelwood procurement of a pulp mill; Hake-, puu- ja puutavaralajimenetelmien taloudellisuus massatehtaan kuitu- ja energiapuun hankinnassa

Abstract

Branch-mass models, applicable for different kinds of technical/economical inspections of timber procurement, based on large data collections of the Finnish Forest Research Institute, were developed in the project. These models are based on the assumption that the branch-mass distribution inside the top-end of different tree-species resembles each-other. The production costs of pulp produced from first-thinning pine were lowest when the minimum diameter of the pulpwood varied between 6 - 9 cm, then the relative costs varied between 101 - 99. The production costs consisted of timber procurement costs, variable industrial timber processing and pulping costs, and secondary product reimbursements. In addition to the calculational inspections, the effects of the dimensions of pulpwood and the harvesting technology on profitability of harvesting of first thinning pine, on debarking, on the chip-size distribution and on fiber properties, were studied in the research. The profitability of harvesting is increased by about 10 % when the minimum diameter is decreased from 7 cm to 5 cm. This requires, however, that the size of the minimum-stem is not decreased
