ABSTRACT :

Despite Chennai being the fifth largest city in terms of area, Chennai is the metro that generates the largest per capita amount of waste in the country. For Chennai which generates 6,404 tonnes of waste daily, the garbage generated by an average household includes 25% recyclable waste, 60% organic waste and 10% hazardous waste. At least 30% of garbage goes into drains, while many vacant plots and pavements have become unofficial dump yards. The city, with about 730 hospitals, also generates an average of 9,898kg of biomedical waste a day. The corporation spends an estimated 6.5 lakh a day on diesel for transporting garbage. Studies have shown that burning garbage in Chennai's dump yards at Kodungaiyur and Perungudi poses severe health hazards, even exposing nearby residents to the threat of cancer. Many people living near these dump yards have complained that air polluted by burning  garbage has caused respiratory disorders. With Kodungaiyur and Perungudi dumpyards moving towards the end of their lifetime, the Chennai Corporation is toying with a new strategy to dispose the daily garbage being collected in the city. Perungudi & Kodungaiyur houses are the two major landfills in Chennai. The refuse generated from in the city is directly dumped without any processing. These dumpyard  are reaching its capacity and plans are being put into place to scientifically close the dumpyards. However, currently no deals have been finalized to do the same. Local people struggle to live and fight for shifting dumpyard couple of years. 

Key words: green house gases, dumpyards, methane, carbondioxide, sensors, test cells, air pollution, landfill gases
