Tire recycling is the process of recycling old tires that can no longer be used efficiently by vehicles into other types of products. In 1989 only about 10% of tires were recycled, but in 2003 over 80% of tires were sent to scrap tire-recycling facilities. Tire recycling is expensive and cannot be accomplished without proper funding. Most problems with scrap tires can be tracked to the lack of funding, control of funding already in the system or the funds collected to solve the scrap tire problem go to support everything except solving the scrap tire problem. Fees are typically collected to assist the tire dealerships in the handling of waste tires left behind when a new tire is purchased. There are no statutes, which require tire dealerships to take waste tires, but most will when a new tire is purchased.
