Bangkok peoples have produced municipal solid wastes at the total volume of 10,000 ton/day, sanitary landfill is the choice as a current waste disposal but causing envirorunental and social impacts. Bangkok Metropolitan Administration (BMA) has studied for the alternative integrated waste disposal for better management to meet the envirorunental standard and to obtain better quality of life. The integrated waste disposal includes the combined technologies of sorting, sanitary landfill, composting and incinerator together. Nevertheless, the concept of external costs/benefits has never been properly mentioned in the waste disposal analyzes in BMA. This paper would compare the external costs/benefits between the current waste disposal by sanitary landfill and the integrated waste disposal. The results of comparison will set into the financial costs and benefits of both scenarios. The conclusions would show the better pictures in wider view for choosing waste disposal management in term of social cost, which is not only the private cost or direct cost of the project as we have already known but also the external cost, which we normally never realized as part of the project costs.
