Zero Waste Energy Development Company

San Jose, California | 90,000 TPY | 4th Quarter 2013

GreenWaste Recovery, ZWE and Zanker Road Resource Management came together to design and construct an innovative dry anaerobic digestion (AD) facility for the City of San Jose’s commercial organics processing services.  This facility will be the largest dry AD project in the world, processing an estimated 90,000 tons per year (TPY) of commercial organic waste that would otherwise be disposed of in a landfill.  The high-quality compost produced will be used to enrich soils.  In addition, the renewable biogas will provide both on-site power for Zanker operations and power for sale to local users of green energy.

Commercial operation began in December 2013.

    • 16 AD digesters + 4 In-Vessel Composting tunnels
    • 2 x 800 kW combined heat & power system
    • Fully enclosed and ventilated waste processing facility
    • Mechanical pre-treatment
    • Accessible piping chamber at digester rear-wall
    • Containerized process equipment on digester roof
    • Dual-mode lean-gas/emergency flare


    • Helps City of San Jose achieve California AB32 mandate by diverting nearly 85% of organic waste from landfills
    • Generates 1.6 MW of renewable power that complies with California’s Renewable Portfolio Standards
    • Reduces fugitive methane emissions from landfills
    • Generates high-quality compost available for use or resale
    • Creates excess electrical power to be sold to Zanker Road Resource Management and California-based electric service providers.
