Eighth International Conference on Case Histories in Geotechnical Engineering
Life Cycle Analysis as a Tool to Assess the Sustainability of Waste Management Practices in Bangalore City
Publication: Geo-Congress 2019: Geoenvironmental Engineering and Sustainability (GSP 312)
ABSTRACT
Bangalore generates around 3,500 tons of municipal solid waste (MSW) per day. The current waste management practices involve preliminary mechanical and biological treatment before landfilling. Assessment of the waste management practices followed by the municipality by using life cycle analysis (LCA) is presented in this study. LCA is also used in the study to explore alternatives to the current practices and handle the waste in a more sustainable way. The analysis is performed in terms of material flow, energy flow, and the impacts of waste processing on the environment. Five impact categories consisting of global warming, acidification, eutrophication, human toxicity, and aquatic ecotoxicity potentials were investigated. The result presents the comparison of open dumping of MSW (which was practiced earlier) with the existing integrated waste management (IWM) system. Results also show that the environmental impact of IWM system with a bioreactor landfill having an energy recovery facility is lesser than the above two cases.
