J-FOR Journal of Science & Technology for Forest Products and Processes: VOL.1, NO.2, 2011 38 To a great extent, the design of large forest products facilities has been based on the assumptions of stable future wood costs and species mix. Mill design and wood supply are dealt with as separate, although connected, calculations. This is essentially an agricultural model in which supply is availab...

Bioremediation of chromated copper arsenate-treated waste wood with one or more metal-tolerant bacteria is a potential method of naturally releasing metals from treated wood fibre. Sampling eight environments with elevated levels of copper, chromium, and arsenic resulted in the isolation of 28 bacteria with the capability of releasing one or more of the components from chromated copper arsenate...

BACKGROUND The forestry and wood products industries play a significant role in CO2 emissions reduction by increasing carbon stocks in living forest biomass and wood products. Moreover, wood can substitute for fossil fuels. Different methods can be used to assess the impact of regional forestry and wood products industries on regional CO2 emissions. This article considers three of those methods...

In anticipating future rates of adoption of new technology in forest products, several uniquely important factors come into play. In this respect, the role of innovations imported from other industries, the effect of raw material shortages, the importance of economic factors in adoption of innovations, and the problems presented by the heterogeneity of wood raw material and finished products ar...

A BSTRACT According to the Heckscher-Ohlin-Vanek theorem, the net exports of a region are determined by relative abundance of the immobile factors of production. Empirical tests of this theory, usually at a high level of aggregation, have frequently not supported it. We find, instead, that data on interstate trade in wood products within the United States are in strong agreement with the theore...
