how much methane a landfill can release. There are various ways of controlling the release of methane from landfill including simply burning the gas off. Landfill gas recovery allows the methane to be used to produce energy. This allows landfill operators to make money while complying with environmental regulations. In addition, companies can qualify for green energy income tax credits, making landfill gas even more profitable.
Provides a "Green" Energy Source
The gases produced by a landfill can be used in place of non-renewable sources for generating electricity. Landfill gas recovery can be used to replace coal and natural gas to generate water vapor to power electrical turbines. This makes landfill gas a renewable energy source. A landfill can produce enough gas to provide energy for a couple thousand homes. Since all landfill produce methane, landfill gas is truly a renewable source of energy.
Improves the Local Economy
Landfill gas recovery can help improve the local economy. The design, construction and maintenance of landfill gas recovery projects creates locals jobs. Local businesses may also enjoy savings from using landfill gas in place of non-renewable resources like natural gas. They additional jobs associated with the landfill project and the additional income businesses gain through having access to cheaper energy lead to indirect job growth.
Reduces Hazardous Emissions
Methane is not the only emission found in landfill gas. Many other organic compounds exist in lower concentrations in landfill gas. Some of these compounds can be hazardous to human health. These compounds are destroyed when landfill gas is burned to generate electricity. As a result, recovering landfill gas reduces dangerous emissions. It also reduces bad odors in the area surrounding the landfill.
Burning landfill gas does generate nitrogen oxides, a component of smog. However, the amount of nitrogen oxides created by burning landfill gas is considerably less than is created when burning non-renewable resources such as natural gas or coal. As a result, landfill gas may contribute slightly to smog but if landfill gas is replacing coal, its use may actually reduce smog. This article is free for republishing
