Landfill Gas to Fuel
Daily, there are millions of tons of municipal solid waste deposited into thousands of landfills and other dumping sites, worldwide. The decomposition of organic material in these places—typically food and paper products—results in the production of methane and other greenhouse gases. Landfill gas (LFG) typically is made up of 50 percent methane (CH4) and 50 percent carbon dioxide (CO2), with small amounts of non-methane organic compounds often present. The methane in LFG is what can be burned off or used as an alternative fuel. Due to methane’s ability to trap heat, it warms the earth 23 times more than carbon dioxide and has an atmospheric lifespan of about 12 years, one much shorter than that of other greenhouse gases. Short lifespan, along with its high heat-trapping potential, make methane elimination from the atmosphere a particularly effective method of combating global warming. Many experts contend that LFG recovery projects that use methane for fuel have become effective tools for combating the effects of global climate change.
