Book Description
The quest for renewable sources of energy has opened new opportunities in the forest industry. What was considered non-merchantable trees for traditional use can now be marketed as feedstock for energy production. This study was set to evaluate protocols for producing woody biomass as an added-value production for renewable cleaner energy. Two forest types (hardwood and pine) were considered as treatments with three replications. Different aspects of woody biomass production were evaluated including cost of production, yield per acre, and efficiency to produce electricity. Data were collected from six in-wood chipping operations in four different counties in Alabama. The chipping operations were integrated within traditional logging operations. The specifics of woody biomass production were collecting, loading and chipping logging residues. A significant difference in cost was found between producing hardwood-chips ($9.68/ton) and producing pine-chips ($7.26/ton). The difference is explained by temporal factors in chipping hardwood. However, hardwood forests were equally productive to pine forests in terms of biomass yield/year/acre.

Book Description
Lord Rutherford has said that all science is either physics or stamp collecting. On that basis the study of forest biomass must be classified with stamp collecting and other such pleasurable pursuits. Japanese scientists have led the world, not only in collecting basic data, but in their attempts to systematise our knowledge of forest biomass. They have studied factors affecting dry matter production of forest trees in an attempt to approach underlying phYf'ical principles. This edition of Professor Satoo's book has been made possible the help of Dr John F. Hosner and the Virginia Poly technical Institute and State University who invited Dr Satoo to Blacksburg for three months in 1973 at about the time when he was in the final stages of preparing the Japanese version. Since then the explosion of world literature on forest biomass has continued to be fired by increasing shortages of timber supplies in many parts of the world as well as by a need to explore renewable sources of energy. In revising the original text I have attempted to maintain the input of Japanese work - much of which is not widely available outside Japan - and to update both the basic information and, where necessary, the conclusions to keep them in tune with current thinking. Those familiar with the Japanese original will find Chapter 3 largely rewritten on the basis of new work - much of which was initiated while Dr Satoo was in Blacksburg.

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
Biomass is a widely available resource, that can be characterized by its high production potential. Enabling the production of different types of biofuels, biomass can be used in both spark-ignition and compression-ignition engines. There is extensive knowledge of the biofuel production process, and technologies enabling the production of biofuels with high caloric value and better physicochemical properties are developed. The biggest barrier in the development of a biofuels market is not the lack of know-how, but economic and political aspects. Biomass for Biofuels presents technological aspects of biomass conversion into advanced biofuels. Also discussed are the influence of growing biofuels markets on the natural environment and social relations as well as economic aspects of acquisition of biomass and its processing into biofuels. In addition biomass characteristics are presented. A definition is provided, and its chemical composition and properties detailed. The focus is on lignocellulosic biomass, whose complex structure is a limiting factor for biofuels production via biological processes. For that reason, echanical, chemical and physicochemical methods that enable an increased availability for the microorganisms used for biomass conversion to biofuels are discussed.
