The Full Circle renewable natural gas (RNG) project in HurleySouth Dakota includes building 4 new anaerobic digesters on the newly built Full Circle Dairy Farm in Turner County. The 7,000 cows that will live on this farm will produce a total of 91.3 million gallons of manure each year. After the farm is operational and the anaerobic digestion project is complete, the methane generated by this manure will be captured, cleaned, and converted into RNG, which can be used for transportation, cooking, or electricity. 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.
