Abstract
With the nation's largest number of registered cars, California generates over 300,000 tons of scrap tires annually. The management of these tires is guided by the California Tire Recycling Act and the California Integrated Waste Management Board (CIWMB). This agency has focused attention on the development of incentive programs for recycling, rather than state subsidies. In addition, research, market development, information, and regulation have shaped the scrap tire program. Currently, 65% of tires are recycled and 10% are reused. The primary end users are crumb rubber (21%), tire derived fuel (14.9%), landfill construction (11.8%), retreading (6.9%), and civil engineering (4.6%). End use incentives are compared for British Columbia, California, Louisiana, Oregon, Texas, Utah, and Virginia.
