Last date for submission of paper: unknown; Contact person: unknown; Anaerobic digestion is not a new process and many successful systems operate worldwide. However, opportunities exist to maximize outputs of existing systems and include management-based goals into new ones. The current industry movement towards receiving and converting food wastes and other materials co-digested with the main digester feed stream will also be included. More and better-managed digesters will help government, the general public, and the private sector achieve renewable energy and greenhouse gas reduction goals.
