Project Overview

Design and construction of a high solid organic waste conversion facility.  The system will convert 7.5 tons of food waste a day from Campbell Soup and other regional food producers along with .5 tons of non-recyclable corrugated materials into natural gas.  The natural gas is used to generate approximately 1,300 kWh of renewable electricity per day, supplying about 37% of ARP’s electricity needs.  This highly complex, innovative system is based on anaerobic digestion (AD) technology developed by UC Davis.
