Follow A Tire
About 1.5% of recycled tires in the US are used to help make products such as shoes, shims, gaskets, and blasting mats for covering rocks before dynamiting. Another way is by shredding or chipping tires. A single pass through a tire shredder produces strips 15 to 40 centimeters long.
Then there ground into mill to produce rubber crumb from 40 to 50 mesh size. Then there frozen with liquid nitrogen and shattered into three parts, rubber , steel, and fabric. Then it's used for highway paving and paving sealents.
One more is landfill engineering. There chips are placed onto plastic liners in the deepest part of the pit where they act as a filter seperating the garbage. Tire crumb can be produced mechanically or by a freezing process.
If these cannot be used, they will be transported to a landfill to be buried. Shredded tires take up 1/8 of the space that normal tires do. To produce chips, they must pass through a two-stage shredder. The shreds can be further crushed and put into a energy incinerators, used to build roads, and several more.
