Grass2Gas: A USDA-NIFA Sustainable Agricultural Systems Project



Summary

C-CHANGE: Grass2Gas is advancing research, education, and extension to support development of a new biobased value chain. The multi-institutional team is assessing ways in which perennials and winter crops can be used more widely as feedstock for anaerobic digestion. The novelty of the project lies in leveraging a successful business model based on the digestion of manure to encompass new agricultural feedstocks, more diverse products, and increased value throughout the supply chain.

In Depth

C-CHANGE USDA-NIFA CAP CoverC-CHANGE is advancing research, education, and extension to support development of a new biobased value chain. This effort will examine production of renewable natural gas and associated bioproducts through the anaerobic digestion of herbaceous biomass combined with manure. The novelty of the project lies in leveraging a successful business model based on the digestion of manure to encompass new agricultural feedstocks, more diverse products, and increased value throughout the supply chain.

C-CHANGE provides integrated activities directed toward feedstock diversification, modulari­zation, process intensification, and stakeholder engagement to reduce supply chain risks, increase product value, and improve production, profitability, and sustainability. Our work is motivated by the pressing need to alleviate social, eco­nomic, and environmental concerns associated with current agricultural sys­tems, and to foster new economic development in rural America.
