A British startup named Tire Collective has created a compact device that fits behind each wheel to capture the bulk of rubber dust shed by tires. This invention aims to reduce particulate emissions right at the source, addressing a long-standing air-quality challenge in modern transport.
Presently, a disposable cartridge within the device acts as a filtration pocket, absorbing roughly 60% of the particles released into the atmosphere. The tire-ground friction charges microscopic rubber particles, which are then drawn into the cartridge by a set of electrostatic copper plates. Over time, technicians remove the cartridge, where the collected dust can be cleaned and fed back into use, extending the life of the capture system.
Manufacturing at scale is anticipated to begin within the next year. To accelerate adoption, the founders are engaging with tire manufacturers and automakers, aiming to refine the technology for mass production and widespread deployment across vehicle fleets.

As Europe sees a rise in electric vehicles that are heavier due to larger batteries and higher torque, tailpipe emissions are expected to drop while tire wear could rise. The added weight and stronger initial torque may accelerate wear, potentially increasing the release of micro-particles into the environment. Eco-activists have not yet raised alarm, but the issue is likely to gain attention as the wheels turn and policy makers tighten standards. This shift highlights the importance of innovations that target both exhaust and non-exhaust emissions, including tire-derived particulates.
