The use of landfill gas is considered a green fuel source because it offsets the use of environmentally damaging fuels such as oil or natural gas, destroys the heat-trapping gas methane, and the gas is generated by deposits of waste that are already in place. 450 of the 2,300 landfills in the United States have operational landfill gas ...
A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide.
LoCI's system is designed to increase methane gas extraction from landfills. The software and hardware provide remote monitoring and control, versus historical practices, which require twice-monthly on-site monitoring and manual adjustments to extract the methane.
America’s landfills—and the environmental havoc they create—are sizable. There are roughly 1,200 landfills currently in operation, and on average, each one takes up about 600 acres of land ...
Landfills are releasing large amounts of planet-warming methane gas into the atmosphere, a study suggests.
These gases can include methane (CH 4), carbon dioxide (CO 2), hydrogen (H 2), and volatile organic compounds (there are approximately 500 others that can be present in trace forms) from the waste on site and its degradation over time. Steps must be taken to prevent this migration from the landfill site as it might enter buildings in the vicinity.
Landfill mining and reclamation (LFMR) is a process which excavates and processes solid wastes which have previously been landfilled. [1] The process aims to reduce the amount of landfill mass encapsulated within the closed landfill and/or temporarily remove hazardous material to allow protective measures to be taken before the landfill mass is replaced.
The distance between probes varies but rarely exceeds 300 metres. The typical regulatory limit of methane here is 50,000 parts per million (ppm) by volume, or 1% methane and 1.5% carbon dioxide above geological background levels in the UK (see "Guidance on the monitoring of Landfill Gas" LFTGN03, EA 2004).
