Southern California Biomethane, LCC in partnership with Victor Valley Wastewater Reclamation Authority, Anaergia Services, LLC, and Momentum, completed an Anaerobic Digester Upgrade and Renewable Natural Gas Production Expansion Project in November 2023 at the Victor Valley Wastewater Reclamation Authority plant in Victorville, CA. The project, funded by a CEC “Ultra-Low-Carbon Fuel: Commercial-Scale Production Facilities & Blending Infrastructure” grant, substantially increased organic and food waste handling and digester throughput capacity, and carbon-negative renewable natural gas production at the facility. This was accomplished by upgrading existing anaerobic digester tanks, installing new mixers, a new food storage tank, and a new thickener, and expanding and adding resiliency to the existing gas treatment and renewable natural gas compression equipment. The renewable natural gas is being sold to Southwest Gas, which in turn sells the product for transportation fuel to its network of end users, displacing gas and diesel, reducing emissions of carbon dioxide, nitrous oxides, and other pollutants.
