Dumpsite remediation has become a crucial aspect of sustainable waste management. This study reviews the current state of knowledge on dumpsite remediation, identifying key gaps in the literature. It explores site investigation, characterization of dumpsites, and remediation techniques, with a focus on dumpsite mining and rehabilitation measures. In the context of dumpsite mining, the study examines the potential recoverable fractions, challenges in recyclability and processing, and the economic aspects of mining operations. For rehabilitation, it discusses the importance of slope stabilization, leachate and gas management, and long-term monitoring strategies. Given the lack of specific criteria for selecting appropriate remediation methods based on site requirements, the study proposes criteria for choosing sustainable approaches. Additionally, case studies are reviewed to demonstrate the successful application of dumpsite remediation for environmental protection and containment, as well as the potential of mining to generate value-added products within a circular economy perspective. However, challenges observed in the case studies, such as heterogeneous waste composition, technological limitations, and economic viability, present significant barriers. The study suggests that overcoming these challenges requires legislative support, infrastructure development, and stakeholder collaboration. The paper concludes with recommendations for advancing circular economy solutions, emphasizing the need for integrated waste management, innovative technologies, and cooperative efforts to achieve sustainable waste management. |
