In South and South East Asia more than 90 % of solid waste is disposed of in open dumps. Considering this legion’s specific climatic conditions, it is necessary to develop strategies to design and operate simple landfills, which are in-transition between dumpsite and engineered sanitary landfill. This approach demands comprehensive research on waste segregation, pre-treatment, control of leachate and landfill gas generation. This paper presents the primary experimental findings of six lysimeters operated under tropical climatic conditions. In these lysimeters, wastes with different pre-treatment, operational arrangement and top cover designs were evaluated. The lysimeter observation consisting of dry and wet climatic conditions reveals that waste pretreatment and operational mode play a significant role in leachate generation rate, and landfill settlement rate.
