In real life, waste tires are usually sold to or given to the tire mender or to the waste collector. The ones that are not badly worn are sold to the driver for further use. The ones that can be refurbished or fire mended are sold to the retreaded or fire mended or tire set processor for processing, and then they are sold to the tire mender or directly to the driver for further use, Severely worn tires (scrap) will be sold to the corresponding processing plant for segmentation, crushing or oil refining, and then further processed. Crushing the waste tires will not only reduce their volume, but also help to make it more convenient for recycling.
