Abstract

Methane (CH4), a potent greenhouse gas (GHG) with a global warming potential (GWP) ~23 times higher than that of carbon dioxide (CO2) is produced by Landfills. There is urgent need to prevent methane emissions from large landfills. Methanotrophs are a group of bacteria that consume methane. In cover soil methanotrophs prevent fugitive methane emissions. In present scenario two general research techniques are performed to prevent methane emissions. First, a dimensionless number method developed based on Michaelis-Menten kinetics. Second, effects of nutrient amendments on methane oxidation and nitrous oxide production were examined by constructing soil microcosms using landfill cover soils. Mehanotrophic activity and community structure can be differentially affected by both landfill gas composition and amendments thus provides insights for best manipulation of methanotrophic processes to better mitigation of GHG emission.
