Bridgestone brings ENLITEN® technology to motorsports through tires using 63% recycled and renewable materials

Bridgestone today announced it will be supplying teams at the Bridgestone World Solar Challenge (BWSC) with tires developed using 63% recycled and renewable materials, designed to help teams meet the extreme demands during the 3000km event, including low rolling resistance, wear and weight. The tires mark the first use of the company's new ENLITEN® technology in motorsport competition.

Bridgestone is supplying a tire with recycled and renewable material ratio (MCN – Material Circularity Number) of 63%, which is an improvement compared to approx. 30 % in the 2019 BWSC event. The recycled and renewable materials used in development of these tires includes recycled organic fiber, recovered carbon black, recycled rubber chemical, recycled oil, and reinforcement material using recycled steel. Furthermore, tires supplied to the cruiser class were additionally developed using rice husk silica and carbon black recovered through pyrolysis of used tire.

"Bridgestone is passionate about contributing to a more sustainable motorsports future at the Bridgestone World Solar Challenge through our ENLITEN tires made with 63% recycled and renewable materials, as well as our collaborative supply chain initiatives. We will demonstrate the new technology through the extreme conditions." said Naotaka Horio, Director, Bridgestone Motorsports. "Additionally, as title sponsor, we are looking forward to helping young and diverse engineering minds from all over the world create breakthrough technologies in the BWSC that can play a role in a more sustainable mobility society of the future."
