Description
The Anaerobic Dairy Digester Program, administered by the Washington State Department of Commerce, funds construction, repair and upgrades of systems that capture methane from dairy manure and other organic waste. These systems connect manure management with renewable energy production, fertilizer and other useful products. The program focuses on dairy biomass processing and measurable reductions in greenhouse gas emissions or untreated effluent.
The funding opportunity includes dedicated support for cover-and-flare manure management projects and projects that have received funding through the U.S. Department of Agriculture’s Regional Conservation Partnership Program. It supports both new anaerobic digesters and improvements to existing systems.
