This study deals with the characteristics and composition of municipal solid waste (MSW) generated in Tiruchirappalli city. The Physical composition of solid waste was studied by segregating it into different component, i.e., kitchen waste, paper, earth and fine material, Plastic bags, leaves, metals, etc. These components were categorized into organic waste and inorganic waste. It was observed that Tiruchirappalli city produces around 65% organic waste and the rest is inorganic waste.
