Introduction
Woody biomass harvesting systems fell and recover woody biomass and transport it to a central location to be processed or directly loaded onto trucks for transport to a biomass-using facility. This can be done concurrently …
Size of ground biomass particles is significant logistically
by Oladiran Fasin
As part of preparing biomass for conversion into biofuels, biomass is ground through mills such as a hammer mill (Figure 1) or a knife mill. The ground biomass particles are then fed into conversion vessels and/or stored …
Small-scale Woody Biomass Harvesting Systems
Introduction
Small-scale timber harvesting systems, including those that can handle woody biomass, are becoming more attractive to the forestry community. A number of non-conventional, small-scale timber harvest systems have emerged that have the physical capability to …
Biomass Transportation and Delivery
Introduction
One challenge associated with transporting woody biomass for energy and bio-based products is that woody biomass in its raw form (e.g. slash, un-delimbed small trees and tree sections) has a low bulk density (1). Low …
Bioenergy
Introduction
Renewable energy is any energy generated from the sun, wind, water, hydrogen, Earth’s natural heat (geothermal), or biomass. In 2003, biomass was the leading source of renewable energy in the United States for the fourth year in a row, …

Societal Motivations and Barriers in Biofuels Arena
by Sudipta Dasmhapatra
Introduction / Background
Understanding the public attitude, barriers to use and adoption of bioenergy crops and fuels is important due to varied stakeholder groups involved in the entire supply chain, beginning with landowners and ending with the …
Pre-processing and Drying Woody Biomass
Introduction
Pre-processing and drying woody biomass are important issues to address in every situation. They particularly affect transportation costs and combustion efficiency at the end-use location. Both should address four critical characteristics of biomass: particle size, …
The Economics of Forest Biomass Production and Use
Introduction
Under current market conditions, cost remains a major barrier to market penetration of forest bioenergy. However, technological advances as well as social, political, economic, and environmental factors, will affect the cost competitiveness of this renewable energy source. In some …
Ash Content
Introduction
Ash from woody biomass comes from the minerals present in the structure of trees and shrubs in addition to any soil contamination. Properties of wood ash depend on a variety of factors including type of tree or shrub, part …
