The Augean Project

The Augean Renewable Natural Gas (RNG) project in Yakima County, Washington, will convert 150,000 gallons per day at George DeRuyter & Sons Dairy into renewable natural gas each year. Brightmark’s investment in the Augean project enables DeRuyter to upgrade its 2007 manure collection system and digester to increase its capacity. A vital component of the project is the construction of a new gas pipeline infrastructure that sets the table for RNG projects for other dairies in the area.
On day one after the digester upgrades were complete, we were out there emptying manure ponds to turn that waste back into useful products and to recycle nutrients. We’re glad for the opportunity to lead the way for others in the industry in this arena.
