The Full Circle Project

The Full Circle renewable natural gas (RNG) project in Hurley, South Dakota, includes building four new anaerobic digesters on the newly built Full Circle Dairy Farm in Turner County. The manure from this farm will produce renewable natural gas each year. After the farm is operational and the anaerobic digestion project is complete, the biogas generated by this manure will be captured, cleaned, and converted into RNG. Full circle is part of the third tranche of projects developed under the Brightmark RNG Holdings LLC joint venture with Chevron U.S.A. Inc.
We're thrilled to have the opportunity to plan this anaerobic digestion project as a component of our new Full Circle Dairy. We are repeat partners with Brightmark for a simple reason: we know that we can trust them to get the job done.

In October 2020, Brightmark LLC and Chevron U.S.A. Inc. originally announced the formation of the Brightmark RNG Holdings LLC joint venture to own projects across the United States to produce and market dairy biomethane, a renewable natural gas. Equity investments by each company in the new venture fund construction of infrastructure and commercial operation of dairy biomethane projects in multiple states. Chevron purchases RNG produced from these projects and markets the volumes for use in vehicles operating on compressed natural gas.
