Vehicle tires have unique and proprietary formulations. Not only are the tire particles harmful because of their morphology but the individual tire components can be leached from the debris during transport resulting in toxicity to aquatic organisms. One harmful chemical, 6PPD-quinone, was transformed in the environment from a tire preservative(4). This chemical is highly toxic at a very low concentration and kills juvenile Coho salmon before they have a chance to spawn.
The most direct, advantageous, and economically feasible approach to mitigating the complexities of tire wear pollution is to capture the tire wear particles at the source for study and recycling in engineered composites. Recycling opportunities include fillers in highway sub-surfaces, sea walls, and other plastic applications. Learn more about this patent-pending solution at GelbKo.com.
