Fremont Community Digester, MI, USA

Fremont Community Digester Project (FCD) is located in Fremont, Michigan. It is a complete mix anaerobic digester plant. This $22m project utilizes proven co-digestion technology to process approximately 100,000 short ton per year of both organic waste and agricultural waste into green biogas (methane). The biogas is used to generate approximately 3 megawatts of renewable electricity and the power is sold to consumers’ energy under a long-term contract. The plant also produces dilute liquid fertilizer and a solid fertilizer for purchase by regional agricultural businesses.
