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.
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.
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 ...
The methane budget report found that waste was responsible for nearly a fifth of global methane emissions in 2020. And while not all of that comes from food waste, a good portion of it does.
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.
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).
According to the EPA’s Greenhouse Gas Reporting Program, methane emissions dropped in seven oil- and natural gas-producing basins by up to 87% from 2019-2023. The drop occurred as U.S. domestic ...
