Every year, 1.6 billion car tyres are sold worldwide in total. The PET fibres used in these tyres represent 800,000 tonnes of PET per year. With regards to Michelin alone, this represents nearly 3 billion plastic bottles annually. That’s why the France-based global tyre maker has been looking for ways that bottles can be recycled into technical fibres for use in the company’s tyres. Now, the company has validated that Carbios’s enzymatic process does exactly that, giving Michelin a step forward in its sustainability plans. Indeed, Michelin describes the development as “a major step towards developing 100 per cent sustainable tyres. Michelin has successfully tested and applied”. Michelin is committed to achieving 40 per cent sustainable materials (of renewable or recycled origin) by 2030 and 100 per cent by 2050.
