The Encina (Calif.) Wastewater Authority and Waste Management have launched a 90-day pilot project to process food waste in as part of a co-digestion process.
The project will be the latest effort for Waste Management using its Centralized Organic Recycling (CORe) technology. It was first launched at a wastewater treatment facility in Los Angeles.
Through the process, which involves anaerobic digestion, plants in some cases are cranking out 10 times the biogas, per volume of water, as when they generated energy from treated wastewater alone, Eric Myers, Waste Management’s director of organics recycling, told Waste360 last year.
The Times of San Diego has more on the latest application:
“We’re excited with the potential positive impact this public-private collaboration can have to address food waste in the region,” said Scott McClelland, assistant general manager for Encina Wastewater Authority.
During the pilot period, Waste Management will transport organic slurry from Orange to the Encina Wastewater Authority plant in Carlsbad. There, the organic slurry will be added into an isolated digester to compare methane production of that digester with others on site.
“Our goal is to offer a viable green solution for diverting food waste from local landfills that aligns with our mission to maximize resource value,” said Ken Ryan, senior district manager of Waste Management in North County. “Utilizing Encina Wastewater Authority’s existing infrastructure and Waste Management’s innovative technologies can help shape the future of food waste diversion in San Diego County.”
