Management of the ever-increasing generated solid waste had been a difficulty for state governments in Nigeria. The high costs connected to this waste management which had encumbered the state budget, ignorance or lack of understanding of resourceful waste management and insensitivity to environmental concerns may have led to partial neglect of this sector. This research paper is aimed at evaluating the rehabilitation potential and the risk level of Igbatoro dumpsite, an Ondo state-managed waste dumpsite which predominantly receives the waste of Akure and its environs. In determining rehabilitation/reconstruction potentials and assessing the risk of the dumpsite, an Integrated Risk Based Approach (IRBA) was considered. The Risk Index (RI) was calculated from the addition of the sensitivity index output with the attribute weightage of the twenty-seven (27) parameters studied. A total risk index of 571.58 was obtained for Igbatoro dumpsite indicating moderate hazard evaluation. Questionnaires distributed to dwellers around the dumpsite also showed that 83.6% of those interviewed agreed that the present management of the dumpsite is poor while 81.8% supported rehabilitation of the dumpsite. Hence, reconstruction of the Igbatoro dumpsite to an endurable and controlled landfill is hereby recommended.
尼日利亚各州政府一直难以应对日益增多的固体废物。这种废物管理的高成本已经给州预算带来了负担，对资源丰富的废物管理的无知或缺乏理解，以及对环境问题的不敏感，可能导致了对该领域的部分忽视。本研究论文旨在评估伊格巴托罗垃圾填埋场的修复潜力和风险水平，该垃圾填埋场是一个由翁多州管理的垃圾填埋场，主要接收阿库雷及其周边地区的垃圾。在确定修复/重建潜力和评估垃圾填埋场的风险时，考虑了基于综合风险的方法（IRBA）。风险指数（RI）是通过将敏感性指数的输出与研究的二十七个（27）参数的属性权重相加计算得出的。伊格巴托罗垃圾填埋场的总风险指数为 571.58，表明存在中度危害评估。分发给垃圾填埋场周围居民的问卷也显示，83.6%的受访者同意目前对垃圾填埋场的管理不善，而 81.8%的受访者支持对垃圾填埋场进行修复。因此，建议对伊格巴托罗垃圾填埋场进行重建，使其成为一个可持续和可控的垃圾填埋场。
