Landfill gas is one of the major anthropogenic sources of methane that has global warming potential over 20 times greater than carbon dioxide. Microbial methane oxidation has been universally observed in different types of soils including landfill cover soil. In this work, the methane oxidation activities in landfill cover and the underlying kinetics were described. The influence of methane and oxygen concentrations, cover materials, temperature, water content and pH on the methane oxidation was discussed. It can be suggested that the microorganism-based methane oxidation is one of the most efficient approaches to mitigate the residue methane emission in landfill to the atmosphere.
