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.
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 ...
Methane capture equipment can be privately owned if the project is located within a designated National Estuary. Public or privately owned equipment to capture methane emitted from manure-containing ponds on animal feeding operations (AFOs), not regulated as concentrated animal feeding operations (CAFOs), and convert the methane to energy is ...
The Sampson County landfill is the state’s largest methane emitter. Neighbors are worried about an effort to capture, sell the gas. A Sampson County landfill project would capture methane.
These projects collect the methane gas and treat it, so it can be used for electricity or upgraded to pipeline-grade gas. (Methane gas has twenty-one times the global warming potential of carbon dioxide). [18] For example, in the U.S., Waste Management uses landfill gas as an energy source at 110 landfill gas-to-energy facilities. This energy ...
The use of landfill gas is beneficial to the U.S. economy by reducing air pollution through the capture and use of methane. As of July 2016, Republic Services operated 69 landfill gas and renewable energy projects. [52] [53] In April 2015 Republic Services opened a landfill gas-to-energy project near Los Angeles at the Sunshine Canyon Landfill.
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.
The same year, the council voted 3–2 against building its 12th high school Marriotts Ridge High School on the Alpha ridge site. [42] [43] 1999, the County refinances $14.2 million in bonds borrowed to pay for the 1993 capping of the landfill. The project took until 2016 to pay down. [44]
