    Grass2Gas Project is Featured in the USDA NIFA Annual Report FY2023

    NIFA's mission is to lead and fund programs that advance agricultural sciences. Our investments are crucial to building the knowledge base within those agriculture-related sciences. Additionally, they are vital to the translation of knowledge into practical applications that ensure all people have access to safe, nutritious, and affordable foods. NIFA investments also help make sure farmers, ranchers, and foresters have equitable access to markets. The Grass2Gas project is highlighted as a success story in this year's Annual Report.

    Cultivating Collaboration: Mid-Project Summary for the Grass2Gas Project

    C-CHANGE is the Consortium for Cultivating Human And Naturally reGenerative Enterprises. Collaborating institutions work to build science-based partnerships for meeting 21st-century challenges in agriculture, technology, and innovation. Partnerships are needed to meet the goals of delivering abundant, affordable, and safe food and energy to 10 billion people while also returning value to people and the land. A major project outcome of C-CHANGE is Grass2Gas (hereafter, simply G2G), a multi-institutional, transdisciplinary partnership working to evaluate the potential of a new bio-based value chain on U.S.

    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.
