Rubber
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, carbon dioxide assisted, thermal-mechanical extrusion process to continuously convert scrap tire rubber into Tire-Derived Polymer, or TDP. The conversion is more than 99% efficient and produces no waste by-products. No devulcanization chemicals or chemical solvents are used in the process. This is the only known cost-effective and environmentally-friendly devulcanization technology that can reverse the effect of vulcanization.
See video below – Tyromer devulcanization technology in action.
Tyromer Devulcanization
Our patented process has successfully devulcanized different scrap tire crumbs – whole-tire, tread-only, ambient grind, cryo-grind, truck retread buffing, OTR retread buffing, etc. from 20 mesh to 60 mesh.
Our technology can also devulcanize non-tire rubbers such as EPDM and silicone rubber for reuse.
The Tyromer technology is the only commercially viable chemical solvent-free process for rubber devulcanization.
It features the following unique benefits:
- Environmentally sound: No devulcanization chemicals or chemical solvents are used.
- Rapid devulcanization: from crumb feed to TDP in less than two minutes.
- Reliable process: continuous operation by mature extrusion equipment.
- High conversion: 99%+ conversion rate of crumb to TDP.
- Energy efficient: less than 400 kWh per Metric Ton of TDP.
- Broad applicability: works for scrap tire crumbs, EPDM, and other rubbers.
