Abstract

Landfill has been considered as the safe and cheapest disposal option of municipal solid waste and has been commonly used method all over the world. Siting landfill is a complex task mainly due to the factors in selection process. For clear identity and selection of appropriate site for landfill, systematic procedures are to be followed and adopted. In this paper, an attempt has been made to select suitable landfill site by using multi criteria decision making methods (MCDM). Based on the detailed examination, five sites were selected as criteria’s of which only one is considered to be the best site for landfill siting. These selected areas are analysed by using the AHP method in order to obtain relative importance weights followed by the application of PROMETHEE and TOPSIS method for the calculation of suitability index with grading value 1.41. The result shows the efficiency of MCDM tools in decision making.
