Results are reported of a preliminary investigation of feasibility of using wood residue to meet energy and raw material needs in the Pacific Coast States. Magnitude of needs was examined and volume of logging-residue and unused mill residue was estimated. Costs of obtaining and preprocessing logging residue for energy and pulp and particle board raw material were estimated and compared with selling values of mill residue fuel, pulp chips, and particle board. Marginally feasible energy use seemed best suited for inplant steam and power production by the wood industry, Although raw material selling values make wood residue use for products more attractive than for electric power generation, even these returns are seldom sufficient to meet the high costs of delivering logging residue for such use alone. Production of higher valued products or public absorption of extra costs of utilization can make these residue management alternatives more feasible.

This chapter presents in a consolidated manner the step-by-step methodology to estimate the electrical energy potential of industrial wood residues considering the dependency of the efficiency of the power plants with their size. A function of the overall efficiency with power was obtained from a best curve fit of real data both taken from the literature and from Brazilian biomass-fired power plants. The methodology was applied to the determination of the electrical energy potential of wood industry residues in the State of Pará (data collected in 2004). Two cases were analyzed: one where a constant electrical efficiency of 25% was considered (independently of the amount of residues generated) and another where the proposed function of efficiency with power was used. Results show that in the State of Pará, the existent 675 sawmills generated 2.95 × 106 t in dry basis. When the dependency of efficiency with plant size is not considered, the electrical energy potential and average installed power (3140.4 GWh and 2 MWe) are overestimated in comparison to the herein proposed methodology (1868.8 GWh and 1 MWe). The present methodology, considering the efficiency as a function of the power, results in an average efficiency of 12.3% (lower than 25%).

This publication highlights the use of wood for energy and includes the most recent statistics on wood energy markets across the UNECE region. It aims to communicate the relevance of wood energy in the region and help bridge information about the forest and energy sectors. It also intends to offer some of the best-available information on the role that wood energy can play in various sectors to support environmental, energy, and socio-economic strategies toward a greener economy. It focuses on commercial wood energy uses in the UNECE including energy generated for cooking, heating and electricity generation.

Wood as an Energy Resource analyzes how wood is seen as a possible source of alternative energy and evaluates the extent of its use. The book covers the trends of wood as fuel in different countries, including its current use, value as fuel, comparison with other fuels, supply, delivery, and transportation. Wood conversion to other forms of fuel and the deployment of advanced wood combustion and conversion systems are also discussed. The text also explains wood resource bases and supplies, as well as the future of wood as fuel. The monograph is highly recommended for experts and researchers in energy conservation as well as renewable and alternative energy sources, especially for those who want to make studies regarding this topic. The book will also be helpful for advocates and environmentalists who want to be educated and educate others about wood as source of energy and fuel.
