Physicochemical Charateristics and Settlement Evaluation of he Landfill with Landfill Gas (LFG) Collecting Facilities

The utilization of landfill gas (LFG) collected from landfills located in the vicinity of municipal areas becoms a growing concern. This study evaluated physicochemical characteristics and settlements of the landfill where the facilities for collecting LFG are installed. The facilities to reuse the landfill gas (LFG) as a energy resource was built in the Kyungnamn S landfill site, whereas the precise estimation of settlements was not performed on design. Therefore, evaluating the safety of facilities against the settlements was also required. In this study; (1) the physicochemical properties of the waste samples of the Kyungnam S landfill site were evaluated, (2) the settlement was calculated by adapting the published methods for the prediction of landfill settlements, and (3) the safety of facilities for collecting LFG against the differential settlements was investigated based on the results of settlement estimation.
