First-Ever Transportation Fuel from Dry Anaerobic Digestion in the U.S.,
South San Francisco Scavenger Taps Zero Waste Energy & Clean Energy

California’s South San Francisco Scavenger is putting in a new fueling station to support its growing fleet of compressed natural gas trucks with fuel derived from local food waste. The compost-based facility will be the first in the U.S. to employ dry anaerobic digestion technology to make transportation fuel, the company says.

South San Francisco Scavenger expects to get 500 diesel gallon equivalents of CNG per day from a new dry anaerobic digestion unit, and will use it to fuel a current fleet of 17 CNG refuse trucks.

“It’s a truly closed loop system,” said Doug Button, president of South San Francisco Scavenger and its Blue Line Transfer affiliate.

“The fully enclosed system is set to process 11,200 tons of material per year, including food scraps and food soiled paper collected from businesses,” states a release, yielding approximately 500 diesel gallon equivalents of of CNG per day.

17 CNG Trucks, and Growing

The time-fill SSF Scavenger station, built by Clean Energy Fuels, will feature an anaerobic digester by Lafayette, Calif.-based Zero Waste Energy. ZEW is employing equipment from BioCNG to process biogas from the digester into pipeline-grade biomethane.

SSF Scavenger has 17 CNG-fueled refuse trucks from Autocar and America LaFrance, says fleet manager John Rossi, out of a fleet of approximately 50 route truck and 20 support vehicles. Besides South San Francisco, the firm’s service area includes Brisbane, Millbrae, Colma and the San Francisco International Airport.

SSF Scavenger purchases about five route trucks per year, Rossi told F&F.
