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

Abstract Lack of full technical specification for biomass fuels and feedstocks is a major source of confusion, uncertainty, and conflict throughout the supply chain. With support from US Department of Agriculture and US Department of Energy, we have interviewed scores of industry participants and reviewed both the scientific and commercial literature to develop a template
Abstract Woody biomass from forestland, urban greenbelts, and residential areas has the potential to provide more than 150 million tons per year of cellulosic feedstocks for biorefineries, pellet fuels, and fermentation. Production sites range from urban lots to large wildland forest tracts. Destinations range from small urban boutiques to large remote industrial complexes. The systems,

Abstract Solid section biomass, such as wood and the node-zone of crop residues, has distinct modes of failure when loaded in cross grain shear. Shear bar design plays a part in determining what the failure mode will be at a given depth of penetration. Other factors include shear location relative to an unconstrained end and
