Selected brick kilns in Palwal District, Haryana
Building infrastructure in India is estimated to grow at a rate of 6.6% per year between 2005 and 2030. The building stock is expected to multiply five times during this period, resulting in a continuous increase in demand for brick and other building materials. With rapid growth of brick production, the environmental aspects of brick making have become a serious concern that requires immediate action to control the emission. Indian brick kiln industry is the second largest brick producer in the world, next to China, having more than 100,000 operating units and producing about 250 billion bricks annually. It employs about 10 million workers and consumes about 25 million tons of coal annually. Coal is the major fuel, apart from coal, a variety of biomass fuels, such as, firewood, dry dung, rice husk bagasse and other agro-residues are. used for firing bricks. Typical brick making process in India is of less energy efficient and hence leads to high levels of pollution. In addition to these emissions from combustion, the life cycle of brick making involves significant fugitive emissions. This study is to measure Air pollutants emission from selected (Ten) brick manufacturing units in Palwal district of Haryana.
