India, the second most populous and one of the fast developing economies in the world is poised to increase its general prosperity and standard of living and in the process is increasing its consumption levels of energy and consumer goods.In general, the quantity and the diversity of MSW are increasing year after year throughout the world, presenting a growing problem for local authorities necessitating new legislation as well as better management practices. Earlier solid waste was considered as an unwanted byproduct of the society but now it is considered as a resource out of place. Though landfills are the most common means of solid waste disposal, the increasing quantities of solid waste is rapidly filling the existing landfills, and new sites are difficult to establish especially in a country like India. Hence efforts are on to find alternatives to landfills and in this direction approaches like source reduction; recycling, composting and incineration are considered.
In this context the present study entitled “Some Experimental Studies on Management of Municipal Solid Waste” (A Case Study of MCE) was undertaken to study the present scenario of MSW management in Andhra Pradesh considering the Municipal Corporation of Eluru (MCE) on the East coast of India as the study area.
Under the present scenario of MSW management in Andhra Pradesh, the status of present MSW management in Municipal Corporation of Eluru is studied in this work and some experimental studies were conducted in the following areas with an objective of better utilization of waste into a useful resource so as to set up model facilities on demonstration basis for implementation and to share the information for dissemination to other local bodies in the state and at national level.
1.To find out the quantification and composition of MSW
2.To estimate the power generation potentiality from MSW
3.To estimate the possible revenue from vermin compost if prepared from the bio- degradable fraction of MSW
4. To study the combustion, performance and emission analysis of plastic diesel derived from plastic waste as an alternate fuel at different fuel injection pressures in comparison with neat diesel.
The implementation of plastic diesel derived from plastic waste on the diesel engine with blends of neat diesel and with cetane number improver at different fuel injection pressures is done and the performance, combustion and emission results are discussed.

Excerpt from the Book
3.2.2 Per Capita Generation of MSW per Day:
The entire municipal area of the City of Eluru is organized into 50 divisions. The entire municipal area is divided into various grids and representative samples were collected from divisions 7, 13,17,23,35 and 50 which are basically residential areas. Enough caution is exercised to represent the various economic and social groups as well as commercial and cottage industries in the samples collected for the study. The sampling divisions contained 836, 814, 1053,776,829 and 852 of households with a population of 4,130, 3,793, 3,632, 4,011, 3,861 and 3,494 respectively. These divisions were selected purposefully since the various economic and social groups as well as commercial and cottage industries are represented here. The present study was conducted between July to December 2008, to understand the quantitative and qualitative aspects of residential solid waste generation.
