UC Davis biodigester

The UC Davis Renewable Energy Anaerobic Digester, which officially opened Earth Day, April 22, 2014, converts organic waste from campus and other sources into clean energy for the campus electrical grid. The anaerobic digestion technology used in the facility was invented by UC Davis professor Ruihong Zhang and licensed to Sacramento-based CleanWorld. (UC Davis)
