Central Marin Sanitation Agency, San Rafael CA. CMSA is a wastewater treatment plant that runs two 80’ anaerobic digesters. The biogas produced by the digesters is transformed on-site into electricity, which powers the plant for over 19 hours each day. The digestate (sludge) is processed and used locally as fertilizer and landfill cover. Details: www.cmsa.us/about-us/power-generation
