The Athena renewable natural gas (RNG) project In South Dakota will include the construction of new anaerobic digesters on three Minnehaha County farms: Boadwine Farms, Pioneer Dairy, and Mooody Dairy. The 11,710 cows that live on these farms produce a total of 55.6 million gallons of manure each year. After the 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. The gas will be injected into the local interstate pipeline system for use statewide.

“As dairy farmers, we can be part of the solution in helping the environment. The digester projects are a win-win because we have the ability to further process the manure, while reducing greenhouse gasses. Agriculture continually evolves. Our improvements in sustainability in the last generation are just short of incredible. Unfortunately, we don’t often tell our story. We are looking forward to partnering with Brightmark to bring these next generation projects to South Dakota.”
