Presentation of Environmental Management Plan for Brick Kilns in City of Qom

Because of locating in the border of desert and having access to suitable clay mine the city of Qom have abundant brick kilns for providing building materials in line with the increasing need and demand for housing due to population growth and the betterment of economic condition and social welfare. These kilns are often active in suburbs for a reduction in transportation costs and utilization of urban facilities. Most brick kilns, plastic kilns and lime kilns are placed in the southeast of the Qomʹs city. There are totally 446 kilns, of which 225 are located in Qom-Kashan road which consume yearly 95520 m3 heavy fuels. The main purpose of this research is presentation of environmental management plan for brick kilns in city of Qom by determining the fuel consumption, soil removal and the procedure used in traditional and Huffman kilns to reach suitable management guidelines by gaining information about the amount of pollutants regarding the kind of fuel and procedure. The amount of pollutants was calculated through measuring the fuel consumption and the amount of soil loss by weighting every bricks and then comparing it with its soil form. Then by determining the amount of pollutants in 10 stations, 12 times a day (totally 120 samples of every one), the quality of breathing air in the region and its correlation with the distance of traditional and Hoffman kilns was obtained. Examination and comparison of pollutants in traditional and Hoffman kilns chimncy deference was done by DELTA 2000 analyzer. Each cube meter of brick weighed 1480 kg which was lighter than its soil form (1687 kg/m3). Both traditional and Hoffman kilns use Mazut as fuel. The amounts of CO and S02 produced in the traditional kilns arc 392.5 ppm and 469 ppm and these amounts in the Hoffman kilns arc 278.5 ppm and 13.4 ppm. Data analysis of kilns location is showing, their relation with the amount of pollutants and has proved the importance and verification of the experiments. Taking into account the environmental standards and regulations kilns arc considered as pollutants and arc known as anti- environmental activities. But environment and industry can be both conserved by changing kilns J.Env.
