For instance, the Middle East discards hundreds of millions of tyres annually. Tyre removal is challenging because tires have a long lifecycle and cannot biodegrade. The traditional means of getting rid of scrap tires have included hoarding, unlawful disposal, and garbage disposal, but these are only band-aid solutions.
Waste Tyre Threat
The perfect breeding environment for snakes, rats, and mosquitoes is a mound of tires. Accidental fires started at tire dumps can burn for several months, spewing out dangerous gases.
Tire disposal is a serious issue since they can destroy landfill caps and liners and rise to the top of the dump. Tires take up a lot of space at landfills and have a void space of 75%, thus they are not wanted there. Many whole tyres cannot be disposed of in landfills; recycling is required in North American and European nations.

Tyre recycling involves disposing of tyres from vehicles that can no longer be used because of wear or irreversible harm (such as punctures). Due to the high production volume and durability of these tyres, they rank among the greatest and most serious sources of waste. Waste tyres can be recycled using three main technologies: combustion, freezing pounding and atmospheric hydraulic milling.
Bearcat can dispose of tyres properly through recycling and other methods. It is best to call them if you have tyres that are no longer of any use to you.
Machine grinding in the background
A scrap tyre being broken apart during the normal mechanical grinding process at room temperature. When tyres are run through a shredder, the tyres are reduced to little fragments. The chips are passed into a granulator, which fragments them and while also eliminating steel and fibre. Any leftover steel is magnetically removed, and fibre is sorted by a combination of wind sifters and shaking screens. Subsequent crushing in supplementary grinders and rapid connectivity radial grinders can produce thinner tyre granules.
Ice-based grinding
By employing liquid nitrogen or other commercially available refrigerants, discarded tyres are ground in a cryogenic process at temperatures around minus 80°C. Pre-treated auto or truck tyres are typically used as feedstock in cryogenic processing, most frequently in the manner of chipping or granules created in the environment.
The tyres become brittle and are simple to crush and break when subjected to such low temperatures. The system may consist of four phases: initial decrease in size, cooling purposes, segregation, and crushing. Compared to previous methods, this one uses less energy and yields rubber crumbs of far higher quality.
Rubber crumbs, also known as crumb rubber, are a byproduct of the ambient/cryogenic grinding of worn tyres. They can be utilised to make new tyres or in a number of landscaping tasks, such as paving walkways.
Pyrolysis
It is the term used to describe the thermal breakdown of used tires either with or without oxygen. Pre-treated auto or truck tire chips are the main feedstock used in pyrolysis. The rubber is heated during the two-phase thermal breakdown process so that it can be broken down into its component parts, such as tire-derived energy (TDF), artificial gas, and charcoal. The substance begins to crack and post-crack as it is heated to 450–500 °C and above.
