Devulcanisation and reclaiming of tires and rubber by
The recycling of used tire by devulcanisation is currently the most virtuous rubber valorisation pathway. Devulcanisation allows the recovery of rubber with physico-chemical properties getting similar to properties of virgin rubber, depending on the devulcanisation process.

Devulcanization of waste rubber for reuse in new tires
Devulcanization of waste rubber for reuse in new tires. Tire rubbers are among the largest sources of waste polymers in the world as their crosslinked structure and the presence of stabilizers result in their resistance to decomposition. With the rise in car ownership in India, continuous generation of used car tires presents sustainable disposal...

De-vulcanization of Tire Rubber | ILLYRIA
No technology at present allows complete devulcanization of rubber. Therefore 100% sol will be never reached even if all cross-links are broken because of the carbon black. Sulfidic cross-linking represents a significant problem in recycling of the rubber vulcanizate and in recovery of the staring material rubber polymer from vulcanized rubber.

Technology: Devulcanization | Tyromer
Devulcanization Technology. When rubber is formed into a tire, it is vulcanized. This is a process where rubber is mixed with sulfur and exposed to heat. The result is a hard, durable rubber product – perfect for making tires. However, vulcanized rubber is difficult to recycle because it cannot be easily reformulated. We use a supercritical,...

Devulcanization of waste tire rubber by microwaves
Reclaiming is considered to be the most attractive method of reusing waste tire rubbers [6]. Devulcanization of waste rubbers, as a reclaiming method, is a technique in which energy is provided to the material in order to destroy, totally or partially, the three-dimensional network formed during vulcanization [7].
