Abstract
The CDM project in the waste management field is also getting to be an important issue, but the semi-aerobic landfill type is not accepted yet for this project. One of the reasons is that the mechanism of waste decomposing by semi-aerobic landfill is not completely clarified yet. In this research project, the gasification rate by the estimation model which is calculated with our passed experiments is compared to the analyzed data by the large lysimeters experiment which is recently started. From this result, the results by the estimation model are close to the same by the analyzed data of Aerobic, Anaerobic and Semi-aerobic landfill type. It is proved that the validity of this estimation model. It will be suggested by these results that to be a validation method for GHGs emission from landfill site and the estimation method of waste stabilization process by different landfill types.
