In this study a laboratory column test has been conducted on a compacted soil modified by a rice-stalk derived biochar to model its methane mitigation capability as a municipal solid waste (MSW) landfill cover material. Preliminary test results showed that gas adsorption was the principal mechanism that reduced the methane emission in the early stage of soil column test. As time passed, microbial methane oxidation became the dominant mechanism over gas adsorption to reduce methane emission. Besides, it was found that the most active zone for methane oxidation was the top 250 mm where the availability of oxygen was adequate for the aerobic activity of methane-oxidising bacteria.
