Landfill Gas - an overview | ScienceDirect Topics

The three main gas constituents (methane, CH 4, carbon dioxide, CO 2, and hydrogen sulfide, H 2 S) are used to characterize landfill gas. In the process, the waste is covered and mechanically compressed by the weight of the material that is deposited above. This material prevents oxygen exposure thus allowing anaerobic microbes to thrive.
