CORe®:Turning Food Into Energy

CORe® is Waste Management’s organic recycling process that converts food waste into EBS®, an organic slurry product used to generate green energy. With CORe®, we collect commercial food waste from restaurants, schools, food processing plants and grocery stores, screen it to remove contaminants such as plastic, packaging and bones, and blend the waste into an engineered slurry that has a consistency like cooked oatmeal. The slurry dramatically increases the production of biogas in anaerobic digesters, which is used to create renewable energy.

Waste Management's CORe® Process

Waste Management’s CORe® process is a local, urban solution that converts food material into our EBS® product through our proprietary process.

EBS® is a high-quality, consistent product produced with more than 99% of the physical contaminants found in urban waste.

The EBS® product is used to create renewable, sustainable energy in partnership with long-term local partnerships, helping them approach zero waste.

Adding additional organic material in the form of engineered slurry to a water treatment plant’s anaerobic digesters typically increases energy output from 50 percent to 100 percent or more. We use simple figures to communicate to the public the environmental benefits realized from their cities’ use of CORe® organics recycling.

CORe® Facilities

Waste Management’s CORe® facilities in Southern California, New York, Boston and New Jersey deliver EBS® to municipal wastewater facilities, which increases their energy output. Waste Management has made over 40 million gallons of EBS® from our facilities to date. Each ton of processed food waste can power between eight and 10 homes.

Case StudyCORe® in Los Angeles County

What began as a demonstration project is now an award-winning, proven technology that is creating renewable energy. Waste Management and the Sanitation Districts of Los Angeles County (LACSD) received the Municipal Project of the Year Award for their Food Scrap-Wastewater Biogas System at the American Biogas Industry Awards. The partnership demonstrates the full-scale co-digestion of urban residential and commercial source separated organics (SSO) at an existing community wastewater treatment facility in a way that can be replicated at other water utilities.

The process involves food waste being pre-processed at the Waste Management facility in Orange, California, through Waste Management’s CORe® process — removing physical contaminants and de-casing plastic and metal containers — to ultimately provide EBS® for energy generation at the Joint Water Pollution Control Plant in Carson, California.
