UC Davis Renewable Energy Anaerobic Digester

The UC Davis Renewable Energy Anaerobic Digester turns food waste into renewable biogas. The facility can handle 50 tons of organic waste per day. A three-stage thermophilic anaerobic digestion system is used with a total working volume of 450,000 gallons. The facility has four California Air Resources Board approved 200 kW microturbines and a 125 kW Rankine-cycle engine-generator for converting waste heat from the microturbines into additional electricity. Approximately 690 kW of the electrical generation capacity is provided by biogas generated at the facility with an additional 235 kW of capacity from landfill gas.
