Abstract
Landfilling is one of the most common ways of municipal solid waste disposal. Degradation of organic waste produces CH 4 and other landfill gases that significantly contribute to global warming. However, before entering the atmosphere, part of the produced CH 4 can be oxidised while passing through the landfill cover. In the present study, the oxidation rate of CH 4 was studied with various types of compost as possible landfill cover. The influence of incubation time, moisture content and temperature on the CH 4 oxidation capacity of different types of compost was examined. It was observed that the influence of moisture content and temperature on methane oxidation is time-dependent. Maximum oxidation rates were observed at moisture contents ranging from 45% to 110% (dry weight basis), while the optimum temperature ranged from 15 to 30 °C.
