Landfill gas is the gas that is extracted from landfills after the waste in landfill starts degrading. Space utilization to dispose of waste is one of the major concerns in every metropolitan. The general trend of disposing of waste is by dumping it openly and then either burning it or by keeping to degrade. In this paper, we intend to design a landfill for treating the waste of Kolhapur city in 4 different landfill sites and extract the gas from each landfill to further use it for energy generation. Further, we also intend to provide a natural liner material by using a combination of bentonite and GCL. We have compared the economics of landfilling procedure and energy generation thus providing an alternative to transform waste into energy. The waste that is dumped openly proves to be hazardous as the continuous fumes due to fugitive emissions leads to degradation in the air quality and also leads to spontaneous combustion. The dumping site in Kolhapur is spread over 60 acres and the problem of spontaneous combustion is a menace for the people living in the neighboring areas. A landfill site would solve the problem of disposing of the waste and also lead to effective space utilization.
