\nMethane is the gas released mostly from landfills in urban areas.
\n<\/section>\n
\nLandfills are significant sources of landfill gas, which is produced by the anaerobic decomposition of organic solid waste. The primary components of landfill gas are methane (CH4) and carbon dioxide (CO2). While CO2 is also released, methane is often present in high concentrations (typically 40-60%) and is a potent greenhouse gas.
\n<\/section>\n
\nLandfill gas collection systems are often installed in large landfills to capture methane for energy generation or flaring to reduce its release into the atmosphere. Other gases like nitrogen, oxygen, and hydrogen might be present in trace amounts, but methane and carbon dioxide constitute the bulk of the gas produced.
