Waste Management to use landfill gas to power trucks

Waste Management is converting a part of its California fleet to run on liquefied natural gas (LNG) to reduce emissions. But the really innovative part is that it will be generating its own renewable LNG from landfill emissions. Generating the fuel locally cuts down on waste while at the same time reducing greenhouse gas emissions from the landfill.

"Houston-based Waste Management Inc. and the Linde Group, a global natural gas producer and distributor, will build a plant to purify and liquefy landfill gas at the waste disposal company's Altamont site near Livermore. The plant is expected to open next year."

"Waste Management already harnesses landfill gas to produce electricity at about 100 of its 280 landfills nationwide. This is the first time the company will convert landfill gas into liquid natural gas to power trucks.

"Landfill gas from the Altamont site currently generates about 8 megawatts of electricity and feeds into the Pacific Gas and Electric Co. power grid, Stoddard said. Some of the additional landfill gas will power the plant, he added, while the rest will be converted to liquid natural gas."

"'It becomes much better when you can avoid that long transportation trip, and produce (the liquefied gas) more locally and from a waste-derived source. That's extremely beneficial,' he said."
