Controlling greenhouse gas emission (GHG) plays a crucial role for developing sustainable municipal solid waste management (MSWM) system. Newtown, a smart city in Kolkata, has implemented a biomethanation plant to convert organic waste into energy after performing central segregation. However, it lacks a disposal facility, so mixed and non-recyclable waste is disposed of at Dhapa landfill. This study examines the present MSWM scenario of Newtown in the context of GHG emission to help policy makers to develop economically affordable waste management (WM) plan for smart urban development. Details physiochemical characterisation of waste from Newtown was done in this context revealing generation of significant heat and landfill gases, which cause spontaneous fires due to biological and chemical reactions. The LandGEM (3.02) model was used to anticipate GHG emissions from the landfill site. The study reveals the necessity of development of sustainable integrated WM plan while controlling particulate matter emissions during WM.

摘要

Controlling greenhouse gas emission (GHG) plays a crucial role for developing sustainable municipal solid waste management (MSWM) system. Newtown, a smart city in Kolkata, has implemented a biomethanation plant to convert organic waste into energy after performing central segregation. However, it lacks a disposal facility, so mixed and non-recyclable waste is disposed of at Dhapa landfill. This study examines the present MSWM scenario of Newtown in the context of GHG emission to help policy makers to develop economically affordable waste management (WM) plan for smart urban development. Details physiochemical characterisation of waste from Newtown was done in this context revealing generation of significant heat and landfill gases, which cause spontaneous fires due to biological and chemical reactions. The LandGEM (3.02) model was used to anticipate GHG emissions from the landfill site. The study reveals the necessity of development of sustainable integrated WM plan while controlling particulate matter emissions during WM.
