Abstract This article describes how the moisture content of baled woody biomass varied during long-term open-air storage under conditions in the Pacific Northwest region of the United States. Large rectangular bales of forest and urban biomass were produced beginning in August 2015 and periodically until June 2016. Weights were measured approximately monthly until the entire

AUBURN, WASHINGTON, UNITED STATES, June 21, 2018 /EINPresswire.com/ — Forest Concepts LLC has been awarded a $1.8 million cooperative agreement from the U.S. Department of Energy’s Bioenergy Technologies Office to address the critical issues of poor flowability, high friction, and highly variable physical properties that have plagued the biomass industry. Biomass materials have a wide
Abstract The productivity of forest biomass collection equipment is highly dependent on site conditions, spatial distribution of biomass, operator skill, and functional design of the equipment used. A prototype woody biomass baler was used to produce large rectangular bales of woody biomass. Rectangular bales enable high payloads during transport and efficient storage at centralized processing

Abstract Baling of fine forest residuals such as tops, branches, and thinnings is expected to reduce the cost of collection, transport, and processing. Baling may enable economical access to currently stranded biomass resources that are inaccessible to large in-woods grinders and specialized chip hauling vehicles. The technical feasibility of baling logging slash branches and tops

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

Abstract Specific energy for comminution and mechanical processing of lignocellulosic feedstocks provides an economically important basis to compare equipment and to provide data for lifecycle analysis of complete systems. Measurement of specific energy during equipment design and development activities enables optimization of design parameters. Forest Concepts developed a torque-arm apparatus and LabView data acquisition method
Abstract Our objective is to apply an understanding of the modes of failure and structural biology to substantially reduce the comminution energy required to produce bioenergy feedstocks. This paper explores the modes of failure for wood materials subject to crushing forces and how they could be used to develop a mathematical model of crushing forces
Abstract Particle shape is increasingly important as a quality parameter for comminuted biomass. Shape affects flowability, pretreatment, rate of conversion, and performance of materials handling systems. This protocol applies to materials that have been subjected to commutation processes including but not limited to chunking, chipping, grinding or milling. Our objective is to enable a uniform
