Abstract
Every year, 800 millions of scrap rubber tires are disposed worldwide as a consequence of the huge increase in the number of vehicles on the road. In the United States alone, about 300 million scrap tires are generated annually and the number is expected to rise by approximately 2% every year. The problem would become more severe due to the rapid growth in domestic consumption in a number of developing countries including China, India, and so forth. In the past, most scrap tires were dumped in landfills. It is, however, widely agreed that landfilling is not a favorable option considering material loss, land wastage and adverse environmental impacts. In light of these drawbacks, regulations have been laid down in many countries to prevent further landfilling. To alleviate the problems brought about by scrap tire stockpiles, it is essential to adopt appropriate waste management strategy to cope with the increasing amount of scrap tires generated every year. Major ways of utilizing scrap tires, including retreading, recycling (in civil engineering and ground rubber applications) and energy recovery (e.g. through combustion in cement kilns and pyrolysis) will be reviewed in this chapter. The suitability of these methods will be assessed in terms of sustainability and the associated environmental impacts.
