Thus municipal solid waste is one of the largest mass of solid materials generated by humanity. This projection clearly shows the need of immediate handling of municipal solid waste (MSW) with appropriate strategic planning and management. The principal means for managing the various materials contained in MSW are by proper collection from the sources, recycling and recovery of energy in waste-to-energy plants, anaerobic or aerobic bioconversion to compost material, and land-filling (Jain and Pant, 1994; Huang et al., 2001).
However, municipal solid waste in India is generally disposed in landfill sites. These sites are generally low lying areas on the outskirts of the town/city and respective Municipal Corporation is generally responsible for collection of wastes from the sources and then its disposal to these landfills. The disposal of these wastes creates a problem primarily in highly populated areas. The more concentrated the population, the greater the problem becomes. Therefore to protect the environment, there is a need to identify and select a best landfill site for disposal of solid wastes because improper landfill sites are constant threat for water and air pollution (Hazardous, 2002; Hanrahan et al., 2006).
