Tires, Recycling, Retreading and recapping
Methods of reusing/recycling the more than 250 million automobile and truck tires which are worn out each year were investigated. The existing methods of reusing tires account for about 30 percent of the volume of scrap tires generated each year. These methods are, Retreading, Reclaiming (by reducing to ground up rubber and fiber), and Tire Splitting (stamp items out of sidewall and tread areas). Several possibilities for reusing/recycling the unused 70 percent were discovered. These methods are as follows: Destructive Distillation -- a method of recovering chemicals from tires by pyrolitic action. It is anticipated that eventually as much as 60 percent of all scrap tires may be reused by this method. Expanded Reclaimed Usage -- The use of crumb rubber as an asphalt additive will improve life and durability of highway paving as much as 300 percent. Artificial Reefs -- The tires are compressed and banded then dumped in the ocean to expand old or create new reefs. Carbon Black -- A method whereby the tire is carburized and the resulting carbon black used in new tire formulation. An investigation of the possibility of using one or more of the above methods for the East Central Florida area indicates that artificial reefs should provide the most useful, least cost method for disposal of scrap tires.
