Most waste disposal sites in developing country are still using open dumping and open burning. However, in developing countries, there are a lot of economic and technical problems with high level landfill technologies of first world countries, which make implementation of improvement is not feasible. Therefore, there is a significant need for transfer of landfill technology that is considered simpler, low cost, and that can be maintained locally. A method that provides these standards, which has recently gathered attention is the Fukuoka Method (semi-aerobic landfill).By life cycle cost analysis method, with the lifespan of the landfill is 20 years and an estimated volume of586,789 m3 (469,431tons), the required capital investment was about US$296,739 (natural clay liner)and US$463,406 (syntheticliner) or about US$0.63 and US$0.99/ton of waste. It is also calculated thatthe total cost of operation was about US$3,187,728 or US$6.79/ton of waste. The closure cost of the landfill was estimated to beUS$278,116 or US$0.59/ton of waste.
