【 摘 要 】

Problem statement: Continuous global environmental crisis and degradation has been achallenge for the sustainability of living on earth. This threat was posed by industrialization, highproducts need, urbanization and population growth activities. As a result, the hazardous wastegeneration has tremendously increased. Approach: Landfill was one of the positive approaches tohandle hazardous waste generated in great quantity. The appropriate selection of landfill site played amajor role to remediate the hazardous waste materials. Attributes to be considered for decision-makingwere selected based on literature, observations with weightage assigned to each attribute following thepair wise comparison method and sensitivity index on a scale of 0 to 1 based on attribute measurement.The attributes were then grouped and ranked following Delphi approach. Results: In environmentalassessment, field based study of three landfill sites such as Melakottaiyur, Pachaiyankuppam andGummidipoondi in Tamil Nadu, India were selected and the sites scored a Risk Index (RI) of 298.75,369.05 and 408.25 respectively. In economical assessment, economic viability related attributes wereanalyzed and the three landfill site such as Pachaiyankuppam, Melakottaiyur and Gummidipoondiscored a RI of 86.1, 94.3 and 131.5 respectively. Conclusion/Recommendations: In environmentalassessment the landfill sites were shortlisted. In order to achieve economic sustainability of the landfill,economic viability related attributes has to be analyzed with high priority and weightage in economicalassessment.
