Energy Recovery Analysis of Perungudi landfill Waste of Chennai, Tamilnadu

Abstract

From this study, the quantity, composition, and energy content of waste material in Perungudi dump yard of Chennai, Tamilnadu, India were examined. Based upon the past waste generation data from the documentary evidence and field data was used to predict the quantity of waste generated in future. This study reviews the potential uses of solid wastes generated at the perungudi dump yard as a sustainable energy source. Physical properties of waste sample like specific gravity (Sg), moisture content (MC), dry density, particle size distribution and unit weight of MSW are analyzed using ASTM guidelines. Proximate analysis (For Physical Characteristics) and Ultimate analysis (For elemental Analysis) were analysed in its ash content, volatile matter (Vm) and fixed carbon (Fc). The net calorific energy stored in solid waste was determined using empirical analysis. The element content like carbon (C), hydrogen (H), oxygen (O), nitrogen (N) and sulphur (S) value in the solid wastes are derived from standard value of material and this values was substituted into the "Modified Dulong's"equation to determine the energy content (GCV) of solid waste. Final estimation of energy output was arrived using Gross Calorific Value (GCV) and Net Calorific Value (NCV).
