News: Tire Recycling & Pyrolysis

MotoE is a racing series for electric motorcycles that is being held for the third year. Michelin is the supplier of tires to the race participants and, ahead of this year’s season, has produced a tire that has significantly less environmental impact due to its high content of recycled materials, including recovered carbon black supplied by Enviro. According to Michelin, tests during the spring showed that the new and more sustainable tires contribute to shorter lap times, while they also heat up more quickly, with improved grip as a result.

According to Budapest Business Journal, Hungary's Hot & Cold Therm (HCT), a company engaging in planning and installation of technical building systems, has developed machinery that uses high-pressure water jet technology to recycle end-of-life tires. The Journal quotes Hungarian state news wire MTI as the source of the information. HCT said the €1 million project was partly supported by the European Union grant. According to the Journal, HCT’s managing director Zoltán Benkő told MTI that the company, based in Tiszalök (184 km northeast of Budapest), has set up a pilot plant that can turn out up to 500 tons of granulate from recycled tires a year. The process, which involves the recovery of end-of-life tire rubber, is completed at room temperature in a closed, circular process, he added.

Michelin reports it has successfully validated the use of Carbios’ enzymatic recycling technology for PET plastic waste in its tires. Carbios confirms the potential of its recycled PET to address all types of applications – from bottles to clothing fibers and now technical fibers. The validation of Carbios’ technology in Michelin’s tests, marks a new step towards 100% sustainable tires. PET (PolyEthylene Terephthalate) is a petroleum-based plastic wherein the monomers used, ethylene glycol and terephthalic acid, come from the transformation of petroleum. PET is the raw material for one of the main textile fibers used in tire reinforcements.
