Case Study - ZWEDC Dry Anaerobic Digestion facility in San Jose

The ZWEDC AD Facility is the largest dry fermentation anaerobic digestion project in the world processing organic waste and generating renewable power. Up to 90,000 tons per year of organic waste (250 tons-per-day) is produced.  The facility consists of 16 AD tunnels, 4 In-vessel Composting Tunnels, and 2 x 800 kW combined heat & power supply units that provide the electricity production.

Managing Director Western US

Yaniv Scherson is the Managing Director for the western U.S. region for Anaergia and is based in Carlsbad California where he leads Anaergia’s projects integrating organics recycling from solid waste with anaerobic digestion and wastewater for production of renewable power and renewable natural gas. He is a licensed professional engineer in California and holds Ph.D. and MS degrees from Stanford University.

Wet AD projects development in California

Sorting organics from MSW for anaerobic digestion offers a cost-effective solution that avoids the additional collection, outreach, or new bins. By utilizing traditional solid waste processing equipment that fits within existing transfer stations and by partnering with existing AD infrastructure the deployment of food waste to green energy production can be quickly ramped-up. Two California case studies (North & South) will be presented of centralized solid waste processing with organics extraction at MRFs coupled with the use of new and existing anaerobic digestion infrastructure.

Owner

With over 100 employees, South San Francisco Scavenger Company serves three cities, operates 40 collection trucks with 25,000 residential and 1,800 commercial accounts, including the San Francisco International Airport.  Food and green waste is anaerobically digested onsite and the biogas is used to fuel the company's collection fleet. 

Dry AD to vehicle fuel project case study

The Blue Line Biogenic CNG Facility has given the ability to reduce the organics going into the landfill by converting that same waste into CNG fuel that powers our collection routes…a true closed loop system. It’s good for us, the cities we serve, and California.  This unique closed-loop system transforms 11,200 tons of food and green waste per year into biogenic compressed natural gas (CNG), produces heat to run the operations and provides high-quality compost. The facility can produce up to 120,000 diesel gallon equivalent (DGE) per year of carbon negative biogenic CNG—enough to fuel up to 18 of Blue Line sister company, South San Francisco Scavenger’s collection vehicles.
