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.
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).
“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.
