Bridgestone Corporation has unveiled a cutting-edge vehicle collection method for tyre and road wear particles (TRWP) to better understand their environmental impact. TRWP are generated through friction between the tyre and road surface, combining elements of tyre tread and road pavement materials.
The new method, showcased at the recent Tire Technology Expo 2025 in Hannover, Germany, promises a more efficient collection of TRWP, enhancing research into particle size distribution, dispersion behaviour, and environmental consequences. The company’s efforts align with its Bridgestone E8 Commitment, promoting sustainable tyre technologies and environmental conservation.
Utilising the B-Mobility proving ground at Bridgestone Innovation Park in Kodaira, Tokyo, the new method combines high-speed cameras and laser light scattering to visualise TRWP dispersion. The device developed by Bridgestone covers the entire tyre, capturing particles effectively. Moreover, using autonomous driving technology and an electric vehicle with regenerative braking, the method minimises interference from exhaust emissions and brake dust.
Bridgestone’s initiative is part of its broader collaboration with the Tire Industry Project (TIP) under the World Business Council for Sustainable Development (WBCSD). The new collection method not only improves recovery rates but also expedites the assessment of TRWP’s environmental effects.
In addition to research, Bridgestone is actively pursuing strategies to reduce TRWP generation, including developing longer-lasting products with enhanced wear resistance.
Through this pioneering method, Bridgestone aims to contribute significantly to understanding and mitigating the environmental impact of TRWP. The company’s initiatives support its broader ecological goals, focusing on sustainable innovations that benefit future generations.
