Bridgestone, a leading tire manufacturer, has taken a major step toward sustainable mobility at the 2025 Bridgestone World Solar Challenge (BWSC) in Australia. From August 24 to 31, the company supplied teams with ENLITEN® tires made from more than 65% recycled and renewable materials—the first use of such advanced tires in the event.
The tires feature recovered carbon black from old tires, developed with ENEOS, and recycled steel produced by Sanyo Special Steel and Nippon Steel. Twaron Next®, a circular-content aramid material from Teijin Aramid, was also used to improve durability and efficiency.
Bridgestone tackled the entire tire life cycle. Wear-resistant ENLITEN® tires reduced team allocations from 24 to 16. Logistics were handled through DHL’s GoGreen Plus program, cutting carbon emissions by up to 85% with sustainable marine fuel. After the race, used tires will be recycled by Australian firm RubberGem into rubber flooring for farms worldwide.
The technology proved itself in competition. Teams equipped with Bridgestone tires won both the Challenger and Cruiser classes, continuing a winning streak of three and four consecutive victories respectively.
Bridgestone says these results highlight how sustainable tire technology can deliver both performance and environmental benefits. The company views the BWSC as a “mobile laboratory,” testing innovations in extreme conditions before applying them to everyday vehicles.
With these advances, Bridgestone underlined its commitment to carbon neutrality and a circular economy, while reinforcing its position as a global leader in sustainable mobility.
