INTEGRATED WASTE MANAGEMENT SYSTEM

The towns and cities have become the centres of population growth and require three essential services viz., water supply, waste water treatment and solid wastes disposal. The tremendous increase in population accelerates the amount of municipal solid waste (MSW) generation. Hence, the solid waste management (SWM) is one of the essential municipal services, to protect the environment, safeguard public health services and improve productivity. In this context the case study is carried out for the integrated solid waste management system for GIET, GUNUPUR. The present population of the institute is 5000 and the projected population is about 7000 with floating population of 50 per day. The study reveals that the institute generates about 1.25 tons of solid wastes per day and its annual production is about 456.25 tons. The study is been carried out for the characterization of MSW, to analyze the physical, chemical and biological characteristics of municipal solid waste. The solid waste samples were collected from four sampling stations, and analyzed for physical and chemical characteristics. The average value of density of solid waste in the residential areas was 201.61 kg/m3. The moisture content of municipal solid waste varied from 10 percent to 20 percent and the pH of the MSW ranged from 7.07 to 7.99. The organic content in the solid waste is in the range of 40 percent to 50 percent a value slightly higher than other such institutions due to more waste inputs from 20 acres of lush green gardens. The average percentage distribution of the physical composition of solid wastes like papers, plastics, clothes, hazardous wastes, metal, glass, combustibles, bones, stones, rubber and organic wastes were obtained as 4.32, 6.52, 3.72, 0.4, 0.15, 0.57, 4.41, 0.11, 31.2, 0.12, 47.91 respectively. The average value of MSW generation rate is 0.201 kg/capita/day. The study also reveals that, the effect of solid waste dumpsite on groundwater quality and soil. The main objective of the present study is to evaluate the impact of domestic solid waste disposal on the groundwater quality. Urban solid wastes have become a threat to environment, both in developed and developing countries such as nuisance from odor, prevalence of unhygienic conditions, groundwater pollution etc.. Hence for a clean and healthy environment the MSW must be managed properly
