Surface gaseous emissions, composition of soil gas and VOC concentration were determined on a French MBT plant, where the biodegradation process is aerobic. Measurements were performed on both the composting windrows and on the landfill cell which receives the sorting rejects. This allowed the comparison of the global methane and CO2 gases, as well as the characterization of the degradation process on the different parts of the site. The performance of the sorting chain allow to obtain a highgrade compost, which can be valorised on agricultural fields, and leads to deposit much smaller quantities of degradable waste than in a classical landfill site, and to lowering seriously the generation of methane. Therefore, landfill gas (LFG) does not need to be recovered and treated by classical means, e.g. flares.
