ESTIMATION OF GREENHOUSE GASES EMISSION FROM DOMESTIC SOLID WASTE OF FAISALABAD CITY AND SCHEMED FORMULA THEREOF

Faisalabad is the third largest city and an industrial hub of Pakistan. The current study was designed to measure the harmful gases emitted from domestic solid waste through microbial activities as well as estimate the potential chemical formula of domestic solid waste of Faisalabad city. The dried samples were undergone chemical characterization through the combustion analyzer to evaluate the true picture of the problem that is being associated with domestically generated solid waste. The results revealed frightening impacts on health and environment associated with gases emission from this sector. In the present study, various constituents of municipal solid waste (MSW) were observed to be in the range of 24.16%; 0.87%; 0.14%; 9.2% and 65.62% for C, N, S, H and O, respectively. The mineral matter suggested a good level of minerals in the waste. The C/N ratio was varying from 23.29/0.87% for the compostable fraction of MSW. The screened samples were also analyzed for their elemental percentage. According to the results, 24.16% of C; 0.87% of N; 0.14% of S; 9.2% H and 65.62% of O were found after chemical characterization of almost 1155 tons of domestic solid waste samples collected from the city. It was observed that high percentage of carbon and sulphur while low percentage of ash and nitrogen favors highest heating values with maximum specific energy content. The results suggest that the disposed off could be developed as a source of energy for domestic and industrial purposes.
