3R Technology is developing an advanced recycling process for end-of-life tires based on ozone-enriched gas treatment combined with thermo-mechanical separation. The process is designed to treat whole tires, without cutting, shredding, or pyrolysis, fundamentally reducing energy demand, system complexity, and material degradation.

​

In the first stage, end-of-life tires are exposed to a controlled flow of ozone-enriched gas. This non-thermal treatment selectively weakens the chemical and mechanical bonds between the rubber matrix and the steel and textile reinforcements. As a result, the tire components can be separated efficiently while preserving the intrinsic properties of the rubber.

​

Following separation, the recovered tire rubber undergoes a proprietary devulcanization process. This step restores elasticity and processability, producing a high-purity reclaimed rubber compound that is free of steel wire and synthetic fibers. The reclaimed material is suitable for demanding industrial applications where consistency and mechanical performance are critical.

​

The technology is currently under development at TRL 5, with laboratory-scale validation completed in our in-house facilities. Ongoing work focuses on process optimization, scale-up, and preparation for pilot-level operation, with the objective of delivering a compact, energy-efficient, and economically viable alternative to conventional tire recycling technologies.
