The use of recycled tyre rubber in the production of new tyres hasn’t really taken off yet, and a main reason for this is because the rubber powder produced by traditional recycling methods doesn’t always reach the level of purity required by new tyre makers – indeed, the European Tyre & Rubber Manufacturers’ Association opines that “while in the EU around 39 per cent of material from end of life tyres is recovered [this includes rubber, but also steel and fabric], recycled materials cannot be used as a substitute for natural rubber in new tyres because of technical limitations.” But now a firm in Hungary claims to have perfected a process that removes every last trace of steel from the rubber powder, thereby overcoming this limitation. Speaking with Tyres & Accessories during February’s Tire Technology Expo in Germany, Gábor Kostyál, CEO of HungaroJet Ltd., described the technology involved and how it can benefit the tyre and rubber industry.
