Because of the high BTU content in tires, they burn intensely and are extremely difficult to extinguish. Applying water causes significant groundwater pollution and the US Fire Administration in 1998 recommended that ecologically it is better to just let the tires burn out rather than try to extinguish them (the better of two evils). Tires dumps can burn for months or years. A tire dump fire in Tracy, California burned for over two years before being extinguished. There were 7 million tires in the dump. Tire fires have severe impacts on air, water and soil. When burned in the open, tires combustion incompletely and emit both conventional air pollutants including particulates, carbon monoxide, sulfur oxides, nitrogen oxides and volatile organic compounds.
More than 300 million tires are discarded every year in the United States, generating a huge problem for landfills since the material doesn't decompose. Since tires are loaded with energy, some businesses particularly cement makers; can use the tires for fuel. Old tires can be used in a variety of ways, such as the rubber covering found on many playgrounds. But many believe burning tires for fuel is the best use.
There are many plants particularly in state of Ohio and New Hampshire who are effectively generating different types of fuel by recycling he used tire. I believe our Govt in Pakistan should work on the alternate fuels and recycling systems as we have enough garbage and can generate some energy.
