Consortium for Cultivating Human And Naturally reGenerative Enterprises (C-CHANGE)
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. farms, with emphasis on the generation of biogas, potentially upgraded to renewable natural gas (RNG), and other associated bioproducts through the anaerobic digestion (AD) of herbaceous biomass combined with manure. Initiated in 2020, the G2G project is funded by a five-year, $10 million grant (Award No. 2020-68012-31824) from the U.S. Department of Agriculture’s National Institute for Food and Agriculture(USDA-NIFA). It represents a partnership between Iowa State University; Penn State University; Roeslein Alternative Energy, LLC; USDA-ARS National Laboratory for Agriculture and the Environment; and 33 partner organizations.

Abstract
The Iowa-based workshop, hosted by the Consortium for Cultivating Human And NaturallyreGenerative Enterprises (C-CHANGE) Grass2Gas (G2G) project on February 22, 2023, was one of a series of online workshops that brought key organizations 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 for biogas/RNG systems.
