Waste to Wisdom Webinar: Production of Quality Feedstock from Forest Residues for Emerging Biomass Conversion Technologies

Presenters: Han-Sup Han: Professor, Department of Forestry and Wildland Resources, Humboldt State University; and Waste to Wisdom Project Investigator; Jim Dooley: Chief Technology Officer, Forest Concepts, LLC; Joel Bisson: Waste to Wisdom Project Coordinator, Graduate Researcher, Humboldt State University; Anil Kizha: Assistant Professor of Forest Operations, School of Forest Resources, University of Maine

What you’ll learn

The Waste to Wisdom feedstock development research team presents innovative methods of producing quality feedstocks from forest residues that are currently underutilized or wasted. The main topics include:

  • Separating/sorting tree tops from logging residues during timber operations
  • Quality of feedstocks produced from tops and limbs/branches
  • Baling limbs/branches for efficient handling and transportation

The presentation covers the study methods used, data analysis, summaries of results, and implication of the research work for forestland owners and biomass energy industry. All these efforts have been performed under the goal of efficient utilization of forest residues as a way to cost-effectively manage forest residues, maximize environmental benefits, and create opportunities for production of bioenergy and bio-based products.

More information

This one-hour webinar is the first of six webinars that will highlight recent research efforts on 1) production of quality feedstock from forest residues, 2) development of three biomass conversion technologies (gasification, torrefaction, and briquetting) that operate at or near the forest, and 3) evaluation of economic and environmental benefits from utilizing forest residues for bioenergy and bio-based products. This $5.88 million research work was funded by the Department of Energy as part of the Biomass Research and Development Initiative (BRDI) program and performed by a team of academics, government scientists, industry partners, and forestland managers along with 15 regional partners in the U.S.

Forest residues, including small-diameter trees, tops and limbs, produced during thinning and timber harvest operations, have long been underutilized and treated as waste materials because of their high collection and transportation costs and low market value. Biomass conversion technologies producing biochar, torrefied wood, and briquettes provide opportunities for significantly increased transportation efficiencies and product market values, especially when these materials are produced at or near the forest operations sites. However, innovative new biomass feedstock methods and technologies that produce high-quality feedstock materials from forest residues are needed to meet feedstock specifications for those biomass conversion technologies, which have limits on feedstock particle size, moisture content, and contamination.

About Waste to Wisdom

Waste to Wisdom is an innovative biomass research project funded by a $5.88 million grant from the U.S. Department of Energy under the Biomass Research and Development Initiative program: Award Number DE-EE0006297. Humboldt State University and 15 regional partners are building on existing research on the conversion of forest residues into bioenergy and other valuable bio-based products.

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives. 

This technology is supported in part by New Technologies for Agriculture Extension grant no. 2020-41595-30123 from the USDA National Institute of Food and Agriculture and membership funding.
