Municipal solid waste management (MSWM) is one of the major environmental problems of Indian cities. Improper management of municipal solid waste (MSW) causes hazards to inhabitants. Various studies reveal that about 90% of MSW is disposed of unscientifically in open dumps and landfills, create problems to public health and the environment. This paper presents an assessment of the existing situation of municipal solid waste management (MSWM) in Coimbatore city. The quantity and composition of MSW vary from place to place, and bear a rather consistent correlation with the average standard of living. Field investigations were carried out for quantification, analysis of physico chemical composition, and characterization in disposal site. Studies carried out in these places have revealed that there are many shortcomings in the existing practices used in managing the MSW. These shortcomings pertain mainly to inadequate manpower, financial resources, implements and machinery required for effectively carrying out various activities for MSWM. Various adopted treatment technologies for MSW are critically reviewed, along with their advantages and limitations. The study is concluded with a few fruitful suggestions, which may be beneficial to encourage the competent authorities/researchers to work towards further improvement of the present system.
