The open dump approach, a primitive version of municipal solid waste disposal remains the predominant option in most of the Asian countries. Problems of shortage of cover, lack of leachate collection and treatment, inadequate compaction of wastes, poor site design and ragpickers working and setting the refuse on fire to recover valuable inorganic items are common at such dumps. It is essential that an appropriate status quo analysis is carried out and an achievable, acceptable and affordable strategy and action plan are developed for implementation in a phased manner. This paper presents the steps that may be initiated to steadily move from open dumps towards controlled dumps and later to sustainable landfills based on the lessons learned from the on going project on "Sustainable Solid Waste Landfill Management in Asia" under the Asian Regional Research Programme on Environmental Technology funded by Swedish International Development Cooperation Agency and Coordinated by Asian Institute of Technology, Thailand. The first step in upgrading open dumps to sanitary landfills involves reducing nuisances such as odors, dust, vermin, and birds. The principle of landfill mining may be used as the driver to convert this challenging task into an opportunity. The possible outcome would include recovery of space for future landfills, soil fraction for growing non edible crops as well as landfill cover material and the plastics for making refuse derived fuel. A natural remediation technique such as phytoremediation using higher vascular plants, though slow, is also worth considering.
