COMPARATIVE LIFE CYCLE ASSESSMENT OF DIFFERENT MUNICIPAL SOLID WASTE MANAGEMENT OPTIONS IN SELECTED WARDS OF BANGALORE

The main objectives of this paper to review the cost of the different municipal solid waste management and to assess the different options using a comparative life cycle appraisal in selected wards of Bangalore. Life cycle appraisal methodology was used for optimum municipal solid waste management strategies in selected wards of Bangalore city. Bangalore is the largest city and business capital of Karnataka state. The population of the city as per the 2011 census is 8,443,675 with the total number of houses 2,101,831. The total of approximately 62.84 tons per day of waste is generated in selected wards of Bangalore. Environmental LCA is a system analysis tool is used to analyze and to evaluate different options that can be implemented to enable the good community solid waste management in the present study. Collected waste to the landfill and composting (Oc I) Optimized route for waste to landfill (OcII) vermin composting (62%) and landfill (32%) (OcIII), Entire waste Incineration (Oc IV), were taken into consideration. An effective Community Municipal Solid waste management system is needed in these selected wards, since the generated CMSW is transported to the dumped yard that has no liner, no biogas capture, etc. Based on the analysis indicates that, the Option OcI and OcIII led to the most adverse environmental impact in the human health and ecosystem quality damage category. Option OcII (Recycling, optimized route and landfilling) is the best option in terms of lower environmental impacts on human health, ecosystem quality and resources and financial requirements. The results also showed that the most eco-friendly scenario to be implemented in the future would be the combination of incineration and landfill (OcIV), further, Oc III option had the least helpful effect on the resources damage category. Theoverall analysis of different options implied that the scenario Sc-1 was the worst options, and followed by OcII and OcIII among the studied options
