EPA AgSTAR’s newest resource is the Anaerobic Digester/Biogas System Operator Guidebook designed to improve the successful development, implementation, and operation of on-farm AD/biogas systems. The Guidebook complements other AgSTAR resources for developing on-farm AD and biogas (AD/biogas) systems. It is designed to be used in combination with the third edition of the AgSTAR Project Development Handbook and with the American Biogas Council’s Digester Operator School. (Enrollment is open for February’s Operator School). As recognized in the acknowledgements, the ABC and members TetraTech, Regenis, UW-Oshkosh, Montrose Environmental, and Newtrient, played key roles in its development. More >>
