San Jose Project Features Zero Waste Energy Kompoferm Technologies
Zero Waste Energy Development Company, Zero Waste Energy and the City of San Jose have teamed up to achieve the ambitious goal of designing and building what will be the world’s largest dry anaerobic digestion facility. At 90,000 tons per year of organic waste, the system will produce 1.6 MW of electricity and an estimated 34,000 tons of high-quality compost. Not only will the system maximize the efficiency of its organics to produce energy and compost, but it will also move the city closer to its Green Vision Goal of Zero Waste to Landfill and Energy from Waste by its 2022 target.

Zero Waste Energy (ZWE)’s high solids AD technology will address the City’s priorities: generating renewable energy and alleviating odor problems. It will resolve the City’s commercial food waste issue, as the Kompoferm system requires minimum pre-processing and can be delivered and loaded using traditional solid waste trucks and loaders. The Kompoferm will also process organics with manageable amounts of contamination, maximize diversion, and produce both local renewable energy and a digestate that can be composted to create a landscape-quality compost.

The San Jose anaerobic digestion project is ambitious in size and scope. When completed, it will be the world’s largest dry AD system, generating 1.6MW electricity. It will feature 16 Kompoferm AD digesters and 4 in-vessel composting (IVC) tunnels to process up to 90,000 tons per year of organic waste throughput in a fully enclosed and ventilated waste processing facility. It will also include 2×800 kW combined heat and power system, mechanical pre-treatment, accessible piping chamber at the digester rear-wall, containerized process equipment on the digester roof and dual-mode lean-gas/emergency flare.
