ABSTRACT

The interest in recycling of rubber has increased in the last decade. This has been driven by the concern about the effect of scrap tires and rubber products on the environment. Many tire companies, trade associations, government agencies, and private recycling firms have expanded their efforts in solving the problem. In the United States an estimated 270 million tires a year are scrapped. It is estimated that over 800 million used tires are stockpiled in various tire piles all over the United States. Large piles are reported in Ohio, California, and Texas.
