CR&R Anaerobic Digester Project

CR&R Incorporated used a $5 million Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP) grant awarded by the California Energy Commission to build a state-of-the-art anaerobic digester at its waste transfer facility in the city of Perris capable of producing enough renewable natural gas to displace the equivalent of 865,000 gallons of diesel fuel each year.

The anaerobic digester, one of four planned for the site, can process 200 tons of residential curbside waste such as green waste and food scraps every day. The renewable natural gas produced by this project will fuel CR&R’s fleet of natural gas garbage trucks and waste haulers. The excess renewable natural gas will be injected into the natural gas pipeline for general use.

The anaerobic digester system will also produce solid and liquid fertilizers as a co-product that can be used for farming and landscaping purposes.
