What is the primary environmental benefit of flaring landfill gas (LFG)?

The primary environmental benefit of flaring landfill gas (LFG) is the reduction of greenhouse gas emissions by converting methane, a potent greenhouse gas, into carbon dioxide and water vapor, which have a significantly lower global warming potential. Landfill gas is composed primarily of methane (CH4) and carbon dioxide (CO2). Methane has a global warming potential roughly 25 times greater than carbon dioxide over a 100-year period. Flaring involves combusting the LFG at high temperatures, oxidizing the methane into CO2 and H2O. While CO2 is still a greenhouse gas, the reduction in the overall global warming impact is substantial due to the conversion of methane. Additionally, flaring can destroy volatile organic compounds (VOCs) present in LFG, reducing air pollution and odor issues. By reducing methane emissions, flaring LFG helps mitigate climate change.
