Abstract

As a comparatively low-cost technology for waste treatment and disposal, landfilling has been adopted worldwide, particularly in developing countries. After one landfill is fully filled, the aftercare management turns into an important issue for municipalities, while the deposited waste is highly complex and condensed. Recent literature has indicated that landfill management plays an important role on critical issues of contemporary solid waste management, including biodiversity preservation, global warming mitigation, landfill mining and land reclamation. This study firstly made a comprehensive literature review on the existing studies in several Asia-Pacific economies, secondly conducted field surveys for the several illustrations of the aftercare management of closed landfills in Japan and Taiwan. Afterward, the findings from the literature and illustrations from the Asia-Pacific region were qualitatively summarized. Based on the results, concrete management strategies were discussed for the aftercare management of closed landfills in the context of land reclamation from important perspectives. For promoting the closed landfill management and seeking for adequate reclamation methods, the ex-post monitoring, impact assessments, and the essential cost-benefit analysis should be implemented with regard to respective reclamation type and local conditions. Using the outcomes of this study, municipalities can formulate concrete strategies to mitigate the risks and negative impacts, and to increase the benefits of landfills from a life-cycle perspective, considering the multi-stakeholders.
