    Building a Resilient Biomass Supply: A Plan to Enable the Bioeconomy in America

    The U.S. Department of Agriculture (USDA) today released a plan that will boost biomass supply chain resiliency for domestic biobased product manufacturing, while also advancing environmental sustainability and market opportunities for small and mid-sized producers.

    The report — Building a Resilient Biomass Supply: A Plan to Enable the Bioeconomy in America (PDF, 2.8 MB) — is one of the key USDA deliverables of President Biden’s Executive Order 14081, which was issued in 2022 and defined bold goals and new priorities meant to catalyze action inside and outside of government to advance America’s domestic bioeconomy.

    Abstract: The Iowa-based workshop, hosted by the Consortium for Cultivating Human And Naturally reGenerative Enterprises (C-CHANGE) Grass2Gas (G2G) project on February 22, 2023, was one of a series of online workshops that brought key organizatins together to discuss the feasibility of farm-based anaerobic digestion (AD) systems that convert biomass from perennial crops, cover crops, and other soil-building crops to produce biogas or renewable natural gas (RNG). The workshop organizers previously conducted in-depth interviews with numerous stakeholders to better understand their perspectives on development of AD and biogas/RNG systems.

    Anaerobic Digestion on the Farm Conference Call for Abstracts

    Iowa State University, the U.S. Environmental Protection Agency (EPA) Region 7 and the University of Iowa have announced an upcoming conference: Anaerobic Digestion on the Farm: Optimizing Environmental and Economic Outcomes for Rural Communities and Beyond. The conference will be November 6-8, 2023, at the Scheman Building at the Iowa State Center in Ames, Iowa. Anaerboic digestion is the natural process in which microorganisms break down organic materials. "Anaerobic digestion offers many environmental and economic benefits," said EPA Region 7 Administrator Meg McCollister. "This conference will bring together government, academic, and private-sector experts, stakeholders, and interested parties to advance understanding of anaerobic digestion and policy implementation."
