This WSU publication provides an abbreviated review of the information found in the longer publication, Renewable Natural Gas and Nutrient Recovery Feasibility for DeRuyter Dairy. It introduces readers to key concerns regarding the profitability of anaerobic digestion systems and includes a discussion of general project costs and potential revenue sources. Additionally, it examines the potential profitability of three alternative anaerobic digester systems: (a) com¬bined heat and power, which is the baseline system; (b) boiler as a substitute for combined heat and power; and (c) renewable natural gas infrastructure.
