Abstract
The present study aims to carry out the streamlined life cycle assessment (LCA) of a solid waste management facility located in Turbhe, Navi Mumbai. The analysis was performed in two stages. First stage involved the enumeration of net environmental impacts of existing facility for the duration of 10 years i.e. from the year 2008 (start of the landfill facility) to 2017 (present date). Based on the first stage results, the system augmentation was proposed by suggesting the modifications in the existing infrastructure. The second stage then dealt with the forecasting of environmental impacts for the existing and proposed augmented infrastructure for the duration of 24 years i.e. from the present year 2017 to 2041, design life of landfill site. Refuse derived fuel facility of the existing system is replaced with gasification unit in augmented one. The environmental burdens associated with the facility were analysed for two impact categories of acidification and global warming. The results showed that the proposed augmented infrastructure is more efficient for the impact category of acidification, while less efficient for the impact category of global warming.
