Moisture Content of Baled Forest and Urban Woody Biomass During Long-Term Open Storage

June 30, 2018 June 12, 2020 / Baling, Publications

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 …

Work Element Time Study of a Prototype for Baling Forest Residual Biomass into Large Rectangular Bales

January 15, 2018 June 12, 2020 / Baling, Publications

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 …

Conceptual Specification of Forest Residues Balers using the Appreciative Design Method

July 29, 2015 July 27, 2020 / Baling, Publications

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 …

Application of Buckmaster Electrolyte Ion Leakage Test to Woody Biofuel Feedstocks

August 10, 2011 June 8, 2020 / Comminution, Forest Concepts Bioenergy, Forest Concepts Research & Development, Publications

Abstract In an earlier ASABE paper, Buckmaster reported that ion conductivity of biomass leachate in aqueous solution was directly correlated with activity access to plant nutrients within the biomass materials for subsequent biological or chemical processing. The Buckmaster test involves placing a sample of the particles in a beaker of constant-temperature deionized water and monitoring …

Square Bales of Woody Biomass for Improved Logistics

October 4, 2009 June 8, 2020 / Baling, Forest Concepts Research & Development, Publications

Abstract The majority of fuels reduction work is conducted by hand crews in the wild and urban interface and near in-forest recreation/administrative assets. Today, most of the biomass is either piled for burning at some future time or is dragged to the roadside for chipping. In many districts, disposal of chipped or whole brush is …

Appropriate Technology Biomass Collection and Handling Systems for Smallwood Utilization

October 18, 2005 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract The continuum of forests and natural areas in need of fuel reduction thinning ranges from wilderness and working industrial forests to urban neighborhood greenbelts and overgrown residential lots. An object of this project is to characterize the problems associated with projects in the true wildland-urban intermix of residential lots to open spaces containing 20 …
