A method is proposed to estimate CH sub(4) oxidation efficiency in landfill covers, biowindows or biofilters from soil gas profile data. The approach assumes that the shift in the ratio of CO sub(2) to CH sub(4) in the gas profile, compared to the ratio in the raw landfill gas, is a result of the ox...
