An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

This book is a comprehensive overview of the forest bioenergy, from feedstock production to end products. The book presents the state of the art of forest biomass production, assessment, characterization, and conversion into heat and power. It starts with forest sources of biomass and potential availability. Continues with the characterization of the forest stands and the availability of biomass for energy per stand structure, including stands managed for timber, non-wood products, and energy plantations. It follows with biomass evaluation and monitoring considering data sources, modeling methods, and existing models. are also addressed. After the initial focus on forest biomass production and estimation, this resource is assessed as a feedstock for energy conversion. Not only current, but also emerging biofuels obtained from forest biomass are considered. Established and emerging conversion technologies for the production of bio-heat and bio-power are examined and the impacts of the conversion systems presented.

From time immemorial, firewood has been a very important source of energy for mankind. Later in history, wood for energy decreased its importance because of other more convenient and cheaper sources, mainly fossil fuels. Today, focus is again on use of forests as a producer of energy with main drivers being climate change, shortage and increasing prices of fossil fuel sources, and safety in energy supplies. However, intensive use of forest biomass is qu- tioned since fundamental ecological processes may be influenced negatively thus making up a trade-off with the benefits of using an otherwise sustainable source of energy. In this book, selected aspects of intensive use of forest b- mass for energy is treated with main focus on ecological aspects like maintenance of soil fertility, recycling of the combustion ash, inf- ence on biodiversity and pests, and economical aspects both at forest owners level and for society. Another focus point is the implemen- tion of this knowledge into decision support, recommendations and guidelines. The geographical scope is mainly the Nordic and Baltic region. The EU-financed project “Wood for Energy, - a contribution to the development of sustainable forest Management” (WOOD-EN- 1 MAN) , make up the frame for the book. Seven partners participated in the project: Forest & Landscape Denmark, Swedish University of Agricultural Sciences, Finnish Forest Research Institute, Norwegian Forest and Landscape Institute, Lithuanian Forest Research Institute, Latvian State Forestry Research Institute, and Estonian University of Life Sciences with Forest & Landscape Denmark as coordinator.

For thousands of years, forest biomass or wood has been among the main energy sources of humans around the world. Since the industrial revolution, fossil fuels have replaced wood and become the dominant source of energy. The use of fossil fuels has the disadvantage of increasing atmospheric concentrations of greenhouse gases (GHGs), especially carbon dioxide (CO2), with the consequent warming of global climate and changes in precipitation. In this context, the substitution of fossil fuels with renewable energy sources like forest biomass is among the ways to mitigate climate change. This book summarizes recent experiences on how to manage forest land to produce woody biomass for energy use and what are the potentials to mitigate climate change by substituting fossil fuels in energy production. In this context, the book addresses how management can affect the supply of energy biomass using short-rotation forestry and the conventional forestry applying long rotations. Furthermore, the book outlines the close interaction between the ecological systems and industrial systems, which controls the carbon cycle between the atmosphere and biosphere. In this context, sustainable forest management is a key to understand and control indirect carbon emissions due to the utilization of forest biomass (e.g. from management, harvesting and logistics, and ecosystem processes), which are often omitted in assessing the carbon neutrality of energy systems based on forest biomass. The focus in this book is on forests and forestry in the boreal and temperate zones, particularly in Northern Europe, where the woody biomass is widely used in the energy industry for producing energy.

In an effort to reduce the risk of wildland fires, many fed. land mgrs. -- incl. the Forest Serv. & the BLM -- are placing greater emphasis on thinning forests & rangelands to help reduce the buildup of potentially hazardous fuels. These thinning efforts generate considerable quantities of woody material, incl. many smaller trees, limbs, & brush -- referred to as woody biomass -- that currently have little or no commercial value. This report determines: which agencies are involved in efforts to promote the use of woody biomass, & actions they are undertaking; how these agencies are coordinating their activities; & what agencies see as obstacles to increasing the use of woody biomass, & the extent to which they are addressing these obstacles.
