Landfill gases have an influence on climate change. The major components are CO 2 and methane , both of which are greenhouse gases . Methane in the atmosphere is a far more potent greenhouse gas, with each molecule having twenty-five times the effect of a molecule of 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 ...
These trace gases include a large array of species, mainly simple hydrocarbons. [16] Landfill gases have an influence on climate change. The major components are CO 2 and methane, both of which are greenhouse gases. Methane in the atmosphere is a far more potent greenhouse gas, with each molecule having twenty-five times the effect of a ...
Methane, or CH 4, is the second most prevalent greenhouse gas that is released into the air, also produced by landfills in the U.S. Although methane spends less time in the atmosphere (12 years) than CO 2, it is more efficient at trapping radiation. It is 25 times greater to impact climate change than CO 2 in a 100-year period.
Although the majority of the natural gas leaks were carbon dioxide, a significant amount of methane was also being consistently released from the pipeline as a result of leaks and breakdowns. In 2001, natural gas emissions from the pipeline and natural gas transportation system accounted for 1% of the natural gas produced. [61]
A gas flare produced by a landfill in Lake County, Ohio. Gases are produced in landfills due to the anaerobic digestion by microbes. In a properly managed landfill, this gas is collected and used. Its uses range from simple flaring to the landfill gas utilization and generation of electricity. Landfill gas monitoring alerts workers to the ...
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.
