Beneficiation of Chipped and Shredded Woody Biomass

Abstract Forest Concepts, with funding from USDA NIFA SBIR program, developed methods and equipment to reprocess low-value dirty forest chips, tree service chips, and hog fuel into high value clean wood fiber and other valuable fractions. Traditional clean sources of mill residuals (sawdust, shavings, and chips) are declining rapidly due to improved sawmilling efficiencies and […]

Shear Processing of Wood Chips into Feedstock Particles

Abstract We have an objective to convert cellulosic biomass raw materials into small particles that are optimized for biochemical and/or thermochemical conversion to liquid transportation fuels. As a side effort, we are interested in producing feedstocks for composite bioproducts, solid biofuels, and other uses. Wood chips that have a typical length of 50mm are a
