VVWRA with highlights of where the new storage tank and organics polishing system (OPS) will be installed.
CalRecycle has awarded Victor Valley Wastewater Reclamation Authority (VVWRA) a nearly $4 million dollar grant for a new co-digestion and renewable natural gas project.
The project will increase the amount of food waste treated at VVWRA while also increasing the amount of renewable natural gas (RNG) produced. The VVWRA project will include the installation of food waste receiving infrastructure, liquid slurry feedstock storage tanks, and an organics polishing system to expand VVWRA’s co-digestion of food waste.
The organics polishing system will help get rid of inorganic material like glass and plastic in the food waste. The feedstock will be delivered via tanker trucks as a pre-processed food waste slurry, polished to remove contaminants, and then co-digested with wastewater sludge.
The project will convert the biogas or methane to RNG and inject it into a Southwest Gas pipeline that runs through VVWRA property. Biosolids will be dewatered and dried, then transported off-site for land application.
The grant funds will be used to help fund engineering and construction, community outreach and education, grant administration, and the purchase of a new organics polishing system, receiving station infrastructure, and feedstock storage tanks. The new equipment will complement the existing infrastructure that went online in January.
The RNG project at VVWRA is part of the effort to meet the requirements of SB 1383 which requires the diversion of 75% of organic waste from landfills by 2025.
