Improvement of the Utilization of Abandoned Quarry as Landfill Facilities

With the increasing amount of waste, the lack of landfill facilities has become the issues. However, it is difficult to construct new landfill facilities due to the “not in my back yard” (NIMBY) phenomenon. The abandoned quarry is a mountainous area damaged by mining. In abandoned quarry areas, there is a high possibility of disasters (such as landslides) and environmental problems (such as illegal waste dumping). In this study, cases of abandoned quarries being used as landfill facilities are investigated and the associated legal system is analyzed, with the aim of improving the utilization of abandoned quarry sites as landfill facility sites. As a result of reviewing the regulations, it was determined that the restoration exemption institution (the most crucial system for using abandoned quarries as landfill facilities) should improve its effectiveness. Therefore, to solve this problem, it is essential to clarify the direction of management at the start of quarries.
