Food Waste to Renewable Energy

By US Environmental Protection Agency.

On Tuesday, November 25, EPA's Pacific Southwest Regional Administrator and City of San José officials will tour the city’s Zero Waste Energy Development anaerobic digestion facility where food scraps are turned into renewable energy and compost for local farms. The facility’s state-of-the-art dry anaerobic digesters use bacteria to break down food waste in an oxygen-free environment, converting it into methane biogas to generate electricity. The facility can digest and compost 90,000 tons of food waste and produce 1.6 megawatts per year. San José aims to achieve zero waste by 2022 and now diverts 74 percent of materials from the landfill through reuse, recycling, composting and anaerobic digestion.
