Description
The Anaerobic Dairy Digester Program, administered by the Washington State Department of Commerce, funds construction, repairs, and upgrades to systems that capture methane from dairy manure and other organic waste. Anaerobic digestion breaks down organic material in an oxygen-free tank, helping reduce greenhouse gas emissions and improve wastewater management while producing renewable electricity or biogas, fertilizer, and other useful products.
The program focuses on practical infrastructure that measurably reduces greenhouse gas emissions and/or untreated effluent at Washington dairies. This funding round includes dedicated allocations for cover-and-flare manure management projects and projects already supported by the U.S. Department of Agriculture’s Regional Conservation Partnership Program.
