The country’s largest waste hauler, Waste Management, achieved a milestone this summer as it put its 1,000th natural gas refuse truck into service. Even more promising, Waste Management’s newest trucks in California are running on the renewable form of natural gas, called biomethane, that requires no drilling since it is produced by collecting and refining the methane gas created at the company’s Altamont Landfill. The Altamont Landfill has been in operation since 2010 and is the world’s largest landfill site producing biomethane. By purifying and liquefying landfill gas into renewable biomethane fuel, Waste Management and its partner Linde North America have been able to produce 13,000 gallons a day of renewable natural gas that is fueling more than 300 refuse vehicles. Altamont has been such a success, that Waste Management is searching for a new site in southern California to convert landfill gas into biomethane.
