Evonik aiming for 20% recycled rubber in new tyres

At present, trade associations in the tyre recycling sector generally recommend that no more than around five per cent ground rubber from end-of-life tyres goes into the production of new tyres. But Evonik is confident of quadrupling this ratio. A team of researchers have been working to counter the restrictions imposed by the chemical structure of recycled rubber, and the company reports having achieved a “key step forward with a process that could make it possible to use up to four times as much recycled rubber in new tyres as in the past.”
