Augean is biogas project in Yakima County, Washington, that will convert 150,000 gallons per day of dairy waste from up to 7,000 cows into 160,000 MMBtu of renewable natural gas (RNG) ) – the equivalent of 1.4 million gallons of gasoline.

The Augean biogas project is also supported by a $1.4 million grant from Yakima County and a $500,000 Rural Energy for American Program (REAP) grant from the U.S. Department of Agriculture.
Collaborating as Augean Renewable Natural Gas (RNG), Brightmark Energy, Promus Energy, and DeRuyter Dairies developed the project. Brightmark Energy will manage the joint venture and Promus Energy, the original developer, will serve as the project manager.
Brightmark’s investment in the Augean project enables DeRuyter to upgrade its 12-year-old manure collection system and digester to increase its capacity and conserve water. DeRuyter anticipates that the project will save the dairies more than a half of a million dollars each year in operating and environmental compliance costs.
