>> Does anyone know how much landfill methane is discharged << Don't know but, "landfills are the third largest source of methane emissions in the U.S. Federal law requires landfill operators to destroy 75 percent of the methane they produce," theenergycollective.com The Environmental Protection Agency estimates that there are approximately six thousand landfills in the United States. Most of these landfills are composed of municipal waste, and, therefore, producing methane. These landfills are the largest source of anthropogenic methane emissions in the United States. These landfills will contribute an estimated four hundred and fifty to six hundred and fifty billion cubic feet of methane per year (in 2000). [8] Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide. Landfill gas also contains varying amounts of nitrogen and oxygen gas, water vapour, hydrogen sulphide, and other contaminants. en.wikipedia.org Waste Management boasts of over 115 landfill-gas-to-energy (LFGTE) facilities, en.wikipedia.org , where they use it to produce electricity. Or they strip the carbon dioxide and water vapor from the land fill gas and sell it as natural gas to homes in the surrounding area. "Waste Management has opened a landfill-gas-to-energy facility at its Superior Landfill and Recycling Center in Georgia, which uses methane gas to power up to 3,400 homes in the surrounding area." renewableenergyworld.com Or use it to fuel their LNG trucks theenergycollective.com ...More than a thousand of WM’s California trash trucks run on liquefied natural gas (LNG) harvested from landfills. “This year we did not buy one single diesel vehicle,’ said Scott Germann, a WM fleet manager. “They’re all natural gas...” ...The process is relatively simple. WM installed nearly 200 wells across the landfill, and each well contains perforated pipes to pull up methane through a vacuum system. The captured gas then travels through a network of pipes to a processing plant, where it is dried and scrubbed of unwanted gases. The purified methane is cooled to -260 degrees, turned into a liquid, pumped into transfer trucks, and sent to regional distribution locations. WM currently produces 13,000 gallons of LNG from the Altamont landfill every day, and it burns with 80-90 percent less carbon emissions than diesel fuel... Or their growing fleet of CNG trucks fleetsandfuels.com Waste Management corporate fleet director Marty Tufte stands ready to answer questions as a Freightliner transfer truck tractor gets a CNG fill-up at new bioLNG-fed station at the Altamont Landfill in Livermore, Calif. on April 17. ---- I think on the global scale, rice paddies and ruminants (cattle, goats, camels. etc.) are among the largest sources of anthropogenic methane emissions, but there are no practical ways to control emissions from rice paddies and goats.
