Landfill Gas as a Renewable Energy Resource

As solid misuse decomposes in landfills, a gas is emitted that is approximately 50% methane (CH4 ) and 50% carbon dioxide (CO2 ), the pair of which are GHGs. LFG energy technologies capture CH4 to prevent it from being emitted to the atmosphere, and can diminish landfill CH4 emissions by between 60% and 90%. This bio methane is 0.2% of total biofuels equipped to road transport, 0.006% of total fuels equipped for road transport (DECC, 2014a), and 0.1% of the 85 PJ of biogas made from landfill sites and the anaerobic digestion of wastes in 2013 (DECC, 2014a). About 85 PJ of biogas were produced in the UK in 2013, and used especially for electricity generation. The welding gas/shielding gas market is projected to fatten from USD 7.17 Billion in 2015 to reach USD 9.46 Billion by 2020, at a CAGR of 5.70%.

As solid waste in landfills decomposes, landfill gas is released. Landfill gas consists of approximately 50% methane, 42% carbon dioxide, 7% nitrogen and 1% oxygen compounds. Landfill gas is a readily available, local and renewable energy source that offsets the need for non-renewable resources such as oil, coal and gas.
