The brick kiln industry is an important small-scale industry in Pakistan that provides employment in rural areas. It involves mixing clay and water, molding bricks, drying them in the sun, and firing them at high temperatures to harden them. Bricks are then used for construction, canal lining, and sewerage drains. However, the industry also causes environmental problems like air pollution from coal smoke, deforestation, water pollution, and health issues. Solutions proposed include converting kilns from coal to natural gas to reduce pollution and deforestation, adding chimneys, using masks, and treating coal for cleaner burning.
