Book Description
Woody biomass is most widely used for energy production. In the United States, roughly 2% of the energy consumed annually is generated from wood and wood-derived fuels. Woody biomass needs to be preprocessed and pretreated before it is used for energy production. Preprocessing and pretreatments improve the physical, chemical, and rheological properties, making them more suitable for feeding, handling, storage transportation, and conversion. Mechanical preprocessing technologies such as size reduction and densification, help improve particle size distribution and density. Thermal pretreatment can reduce grinding energy and torrefied ground biomass has improved sphericity, particle surface area, and particle size distribution. This book focuses on several specific topics, such as understanding how forest biomass for biofuels impacts greenhouse gas emissions; mechanical preprocessing, such as densification of forest residue biomass, to improve physical properties such as size, shape, and density; the impact of thermal pretreatment temperatures on woody biomass chemical composition, physical properties, and microstructure for thermochemical conversions such as pyrolysis and gasification; the grindability of torrefied pellets; use of wood for gasification and as a filter for tar removal; and understanding the pyrolysis kinetics of biomass using thermogravimetric analyzers.

Book Description
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.

Book Description
This Special Issue looks forward as well as backward to best analyze the forest conservation challenges of the Caribbean. This is made possible by 75 years of research and applications by the United States Department of Agriculture, International Institute of Tropical Forestry (the Institute) of Puerto Rico. It transforms Holocene-based scientific paradigms of the tropics into Anthropocene applications and outlooks of wilderness, managed forests, and urban environments. This volume showcases how the focus of the Institute’s programs is evolving to support sustainable tropical forest conservation despite uncertain conditions. The manuscripts showcased here highlight the importance of shared stewardship and a long-term, hands-on approach to conservation, research programs, and novel organizations intended to meet contemporary conservation challenges. Policies relevant to the Anthropocene, as well as the use of experiments to anticipate future responses of tropical forests to global warming, are reexamined in these pages. Urban topics include how cities can co-produce new knowledge to spark sustainable and resilient transformations. Long-term results and research applications of topics such as soil biota, migratory birds, tropical vegetation, substrate chemistry, and the tropical carbon cycle are also described in the volume. Moreover, the question of how to best use land on a tropical island is addressed. This volume is intended to be of interest to all actors involved in long-term sustainable forest management and research in light of the historical lessons and future directions that may come out of a better understanding of tropical cities and forests in the Anthropocene epoch.

Book Description
The fed. gov't. is placing greater emphasis on thinning vegetation on public lands to reduce the risk of fire. To defray the cost of thinning efforts, it also is seeking to stimulate a market for the resulting material, including the smaller trees, limbs, & brush -- referred to as woody biomass (WB) -- that traditionally have had little or no commercial value. The increased use of WB faces obstacles, including the high cost of harvesting & transporting it & an unpredictable supply in some locations. This report: (1) identifies key factors facilitating the use of WB among selected users; (2) identifies challenges these users have faced in using WB; & (3) discusses any insights that these findings may offer for promoting greater use of WB.

Book Description
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.
