Every year Canadians use and discard more than 28 million tires. From a secondary resource perspective, this represents a significant amount of material — about 210,000 tonnes of rubber, 40,000 tonnes of steel and 15,000 tonnes of fabric. The challenge in Canada, as in other countries, is to turn what has been typically thought of as a waste problem into a resource and opportunity. This means finding effective ways to recycle old tires into value-added end uses.
