Closure of municipal solid waste dumps. Site rating for odor impact

Abstract

More than 60% of the waste dumps in India are within 500 m from the communities. The odor impact from these sites may be the sole criterion to prioritize these sites for closure/remediation. The existing rating systems do not consider odor impact in their assessment. A new system, proposed in the study, employs seven parameters derived from the literature review and selects their ratings based on data obtained from a survey of waste dumps in Indian cities having population more than one million and expert judgment. Application of the new system to the waste sites with continuously varying characteristics shows that the scores are spread over the full range of 0-1000 and have minimum clustering. The sensitivity analysis of the new system shows that the system exhibits medium to high sensitivity to five out of seven parameters employed in the system. The odor impact ratings for the fifteen waste dumps from the new system prioritize these dumps into three categories for remedial action and help suggesting a particular cover alternative for these dumps.

Sustainable landfill sites selection using geospatial information and AHP-GDM approach: A case study of Abha-Khamis in Saudi Arabia

“…Many researchers [ [ [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] ]] advocated prohibiting the disposal of solid waste in open areas owing to the inherent threat of air and groundwater pollution, serious health, aesthetic and environmental problems, property depreciation, fire, and explosion owing to spontaneous combustion and slope instabilities in some hilly areas. Researchers [ [ [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] ]] have highly recommended the application of geospatial techniques for integrating waste management strategies (WMS) into urban planning to replace expensive and time-consuming ground measurements for solid waste landfill selection and management [ 4 , 19 , 39 ].…”
