Abstract
The selection of municipal solid waste (MSW) disposal/ treatment alternatives is a perplexing task since the number of options available and each one has its pros and cons. In the present work, the ranking of MSW treatment/disposal options was done using the multiple criteria decision making (MCDM) technique-analytical hierarchy process (AHP). The options considered were open dumping (OD), sanitary landfill (SLF), composting (COM), refuse-derived fuel (RDF) and incineration (INC) most commonly used solid waste treatment/ disposal methods in developing nations. Evaluation of each option was made under three main criterias : economic aspect, technological aspect and social and environmental aspects and under each criteria aspect, various sub-criterias were considered. The weightage of each criterion parameter was decided based on a questionnaire survey among experts. The results show that composting has the highest priority (0.26) and incineration receives the last priority. Sensitivity analysis was performed to check the stability of alternative ranking by varying the weightage between zero to one for all three main criterias. It was found that results were consistent in a wide range. So for decision-making authorities, it will help choose suitable options for the success of the whole waste management programme.
