CleanWorld’s Sacramento BioDigester Uses Off-Spec Food,
BioCNG Cleans & Clean Energy Fuels a Growing Truck Fleet  

Sacramento’s Atlas Disposal claims a U.S. first with a facility dedicated to making biomethane for vehicles with non-landfill organic waste material other than manure or sewage. The resulting compressed natural gas is fueling Atlas refuse trucks and other vehicles.

CNG-fueled Autocar roll-off operated by Sacramento's Atlas Disposal, which makes its own biomethane based in significant part on waste food and beverage products.

CleanWorld Partners of Gold River, Calif. processes the waste material – a significant percentage of which is off-spec, expired or otherwise distressed food or beverage product that would otherwise be landfilled.

CleanWorld employs an anaerobic phased solids (APS) process to make biogas at the Sacramento BioDigester located at Atlas Disposal’s South Area Transfer Station in southeast Sacramento.

BioCNG purifies the biogas into biomethane, removing carbon dioxide and other impurities. Clean Energy Fuels compresses it, and dispenses CNG to Atlas and other customers.

‘A Driving Force for Fleets’

BioCNG, formerly a product brandname of Cornerstone Environmental, is now a separate Madison, Wisc.-based entity, notes company president Matt Davies.

Atlas operates 15 CNG-fueled Autocar trucks now and has five on order out of a fleet of 55, says sustainability director Andrea Stephenson.

The City of Sacramento is a customer too, with 11 rear-loader Autocar trucks and three Freightliner-chassis Elgin sweepers on order, all to fuel at the Atlas Clean Energy station when they arrive in December, says city fleet manager Keith Leech (who doubles as the local Clean Cites coordinator).

These pallet-loads of popular food products, including Campbell’s Soup and V-8 vegetable juice, are from lots for one reason or another deemed not fit for sale. CleanWorld processes them into biogas, which is in turn purified into biomethane and dispensed as CNG at the Atlas Disposal yard in southeast Sacramento. Clos des Ducs hard cider and lactose-free Lactaid dairy substitute were among the other distressed products waiting to be processed at the Atlas facility on September 26.

“This will be a driving force for fleets,” he told F&F. The city is able to deploy NGVs without having to build a fueling station, and can more readily urge vehicle operators in sectors other than refuse to move to the renewable fuel, Leech says.
