ENVIRONMENTAL RANKING OF LANDFILL SITES AMONG n-ALTERNATIVES

In almost all cities, the solid waste generation is increased dramatically and becomes a great challenge today to municipal authority for its collection and safe disposal. Continuous uncontrolled generation of solid wastes forces the existing landfills to become exhausted rapidly[2-3]. Other hand the chance of availability of open land for future provision of landfill in a city is now very less. At present no sanitary landfill technique is practiced for disposal of wastes rather wastes are dumping crudely in a open field without any environmental protection. This indiscriminate disposal of wastes leads to significant degradation of environment and spreads diseases nearby locality of landfill site[4]. Naturally every landfill has an independent grade of acceptability to local authority in respect of their ‘Land Area’; ‘Daily loading of wastes quantity’; ‘Environmental adverse impact to nearby area’ and ‘Cost of land’ etc. In this paper a methodology of Neutrosophic Fuzzy (NSF) model has been introduced to select the environmentally best acceptable landfill out of n-alternative and make a ranking among them. To validate the model, a case study on three landfills of Delhi(capital of India) is presented here.
