Abstract: Methane (CH4) emission from landfills ranks as the third major source of anthropogenic emission. It has been observed that atmospheric CH4 concentration is more than doubled in last 150 years.CH4 has 23 times more global warming potential (GWP) than that of carbon dioxide (CO2). Therefore, the growth and field application of cost-effective techniques are essential for decreasing the rate of CH4 emissions from landfills to minimize the associated risk of global warming and human health. Microbial oxidation of CH4 has been universally observed in a variety of biomitigation system. The present paper attempts to describe the key issues linked with CH4 oxidation process in landfill biocover and the underlying kinetics of CH4 oxidation. Influence of several controlling parameters, such as CH4 and oxygen concentration, properties of the cover material, temperature, moisture, pH on CH4 oxidation in landfill biocover system is also discussed.
