Rural Energy for America Program - Financial incentives have increased the deployment rate of manure digester systems. For example, grants and loans awarded by USDA Rural Development through the Farm Bill have been one of the primary methods for farms to partially fund installation of commercially proven livestock waste digestion technologies.
The AgSTAR Handbook is a comprehensive manual that provides guidance on developing biogas recovery systems at commercial farms.
Common Safety Practices for On-Farm Anaerobic Digestion Systems (PDF) (25 pp, 2MB), which identifies the major hazards associated with anaerobic digester systems and outlines practices to ensure a safe and successful work environment for facilities with these systems.
AgSTAR has put together a brief summary of state air, solid waste, and water permitting requirements for on-farm anaerobic digester systems that digest organic wastes and manure on the Permitting Practices page. It also presents an overview of the federal regulations that affect these systems.
The USDA Natural Resources Conservation Service's National Conservation Practices table contains information regarding Plug Flow Digesters, Complete Mix Digesters, and Covered Lagoons as Anaerobic Digester Conservation Practice Standard - No. 366 (PDF) (8 pp, 144K, About PDF).
Anaerobic Digestion Capital Costs for Dairy Farms (PDF) (2 pp, 188K, About PDF) is an analysis of itemized vendor cost quotes that provides preliminary guidance on estimating capital costs. Please note that data in the document reflects costs based on quotes for systems designed in 2003–2009.
