Innovative local composting and biogas facility leads the nation
SAN FRANCISCO - Today, the E.P.A. and City of San Jose will celebrate the city's successful food-waste-to-energy plan at a tour of the nation's 1st large-scale commercial anaerobic digestion facility, privately owned and operated by Zero Waste Energy Development Company.
"Thanksgiving is a great time to focus on reducing food waste, the biggest single material still going to landfills," said Jared Blumenfeld, EPA's Regional Administrator for the Pacific Southwest. "By turning food scraps into compost and renewable energy, San Jose and Zero Waste Energy Development are helping fight waste and climate change."
The San Jose compost and biogas plan and Zero Waste Energy Development (ZWED) facility supports the city's goal of achieving zero waste by 2022. The city currently diverts about 74 percent of waste material from landfills through reuse, recycling, composting, and anaerobic digestion.
"Our strong public-private partnership with ZWED exemplifies our bold Green Vision," said San Jose Mayor Chuck Reed. "We're diverting waste from our landfill and converting it to energy by collaborating with ZWED at the world's biggest anaerobic digestion facility. This is plan is a win-win for our businesses, our community, and the environment."
During its 1st 10 months of operation in 2014, the ZWED facility has recycled in excess of 30,000 tons of food scraps from restaurants and grocery stores that would otherwise go to the landfill. This food waste generates 500 kilowatts per hour of electricity that is used to power onsite operations, and it has produced approximately 6,000 tons of compost. The facility is capable of digesting and composting 90,000 tons of organic waste per year and is expected to produce 1.6 megawatts and sell excess power to the grid in early 2015.
"We're pleased to have the E.P.A. and City of San Jose join in celebrating our 1st anniversary of the opening of our facility," said Richard Cristina, president of ZWED. "We're excited to showcase the tremendous success of our partnership to keep San Jose's commercial wet waste out of landfills while creating a high quality compost and renewable energy."
San Jose garbage, recycling and composting systems start with state-of-the-art facilities where all commercial waste is 1st sorted before anything is sent to the landfill. Organic and food waste is moved to the ZWED facility, where 16 anaerobic digesters use bacteria to break down the material in an oxygen-depleted environment to create a biogas rich in methane. The gas in turn fuels a combined heat and power plant that generates electricity for adjacent recycling operations.
California recently announced the recipients of $14.5 million in grants to reduce greenhouse gas emissions from food and other organic waste going to landfill. 5 plans in California will each gain $2.5 to $3 million to expand or develop anaerobic digester or composting facilities similar to San Jose's.
EPA's Food Recovery Challenge and new Reducing Wasted Food & Packaging Toolkit encourage businesses and organizations to reduce food waste and help feed people in need. Participants donated in excess of 98,000 tons of food and diverted in excess of 375,000 tons of wasted food from landfills last year, cutting greenhouse gas emissions equivalent to taking 85,000 cars off the road.
