Invited Session: Closing Dumpsites

Technical Problems and Challenges of Closing Open Dumps (1 CEU)

Room 323

Open dumps remain as the main waste management and disposal method in most developing countries. The most noticeable problems at any open dumps are the widely dispersed uncovered waste that is easily contributed to air blown litters, almost no application of daily cover soil, poor access roads, open burning of waste, no compaction of waste or control of waste placement, poor recording keeping of incoming waste, scavenging at the working face, no security fence or check points, presence of vermin, animals and other vectors, no odour, leachate or gas collection and treatment systems, and on top of all, no planning or engineering and monitoring measures or control systems. All these problems and issues are real challenges when closing of an open dumpsite. The presentation addresses these common problems as challenges when closing open dumps in developing countries and aims to stimulate audience participation and discussion. Several innovative solutions and alternative closure materials usage such as bio-covers are worth mentioned and discussed. A traditional U.S. Subtitle D closure system may not be suitable for these developing countries, considering the material availability, cost-benefit and overall environmental protection performance.
