Municipal solid waste (MSW) disposal has become major issue for the city of Ahmedabad, India. Development, concentrated population and economic growth have led to a substantial increase of MSW generation. Therefore, the objective of the study was to characterize MSW for selection of waste processing technology. To provide a solution for sustainable processing and for safe disposal of fresh MSW, Abellon Clean Energy Ltd joined forces with Ahmedabad Municipal Corporation (AMC) under Public–Private Partnership (PPP) to establish a 14.9MW advanced controlled combustion-based waste to energy (WTE) generation facility to process and dispose 1000 tons/day of fresh MSW. For waste characterization, samples ( n =201) were collected from the Pirana waste dumping site using quadrate sampling method. A yearly weighted average Low Heating Value (LHV) of 9.85/kg and ash content 25.12% for unsegregated MSW makes controlled combustion with electricity generation an eligible technology. After combustion, the waste volume is reduced by 75%. The 14.9MW WTE facility replaces 417 t coal/day, reducing greenhouse gas (GHG) emissions of 300.38 tCO 2 eq/day through coal replacement, while avoiding 735.24 t CO 2 eq/day on account of landfill emissions from MSW dumping. Waste to energy is the fastest solution to reduce waste volume by generating electricity through reduction of GHG.

Ahmedabad is a big city with a population of six millions of people and the rate of population is increasing day by day. This phenomenon has led to the exponential growth in consumption. The population growth is largely responsible for the growing solid waste at the Pirana dumping site, which is being managed by Ahmedabad Municipal Corporation (AMC). Various type of waste from large-and small-scale industries are collected at the Pirana dumping site in Ahmedabad by AMC. The large amount of waste at the Pirana site has increased the toxic gases such as carbon dioxide, carbon monoxide, sulfur dioxide, methane and nitrogen dioxide due to the combustion. Although most of the waste is recycled in some ways, the rapid rise in dumping site causing the spreading of pollution has led the increment in temperature. This has led to affect the health of the people living around the dumping side. 1 (Wanwari et al., 2018). Moreover, water pollution of Sabarmati River has become a major problem due to contaminated waste emanating from the surrounding factories. To overcome aforementioned issues, AMC, through its waste management techniques, collecting waste across the city using various methods. The present study has been done on this issue keeping in view the existing management practices and environmental conditions of Ahmedabad.
