Deep inside landfills, bacteria decompose organic wastes in a low oxygen environment. this anaerobic decomposition results in a mix of gases called landfill gas, which consists of about 50%

Methane

Explanation:

Methane is a greenhouse gas considered more potent than carbon dioxide in creating a greenhouse effect. Landfills also produce carbon dioxide gas. Therefore, measures are usually taken on landfills to prevent global warming. Such measure includes; capturing and collection of the gas and the use of methanotrophs bacteria on the soil over the landfills to convert the produced methane into organic compounds.
