The present study would focus on locating all the municipal solid waste disposal sites including the dump yards within 600 square kilometer area of the Chennai City using GIS and monitoring the amount of GHG from the two major dump yards using CH4-CO2 sensors installed at the hotspots on the dumpyards.
One densely populated area within 5 km distance of Perungudi and Kodungaiyur landfills will be identified as a source of Municipal solid waste generation. Non-spatially varied data like atmospheric gas concentration pressure, temperature, moisture content & temperature of cover soil will be recorded. Ten hotspots on each of the disposal sites will be identified to install the CH4-CO2 sensors. A 2m X 2m X 2m test Cell will be constructed as shown in the fig. 1 to monitor and record the GHG emissions from each of the hotspots (locations where CH4-CO2 emissions are more) at varying depths, on the dump yards on a continuous basis for a year at periodic intervals. A total 100 CH4-CO2 sensors will be installed to collect the GHG emissions.
- To measure the Green House Gas concentration using CH4-CO2 sensors installed on the identified hotspots on the Kodungaiyur and Perungudi dumpyards on periodic basis.
- To record and transmit the sensed data to the web server through the OGC standard sensor web.
- To monitor and analyze the CH4-CO2 (GHG) emissions from the web server for decision-making.
- To develop a Model using the procured data (GHG concentrations) incorporating age of the dumpyard, waste dissociation rate and the GHG dispersion rate.
The output of the study will be a data source of the continuous Green House Gas emissions which are silent killers of the environment. The concentrations of Green House Gases indicated by the sensors will sensitize the authorities to lay laws so as to insist the public to strictly practice the concepts of effective solid waste management at the households. On the whole, the project output would serve as siren in warning the dreadful effects of municipal solid waste to the air environment and would be an information provider giving the potential of wastes that can be converted to energy.
