Tyre wear is one of the biggest sources of microplastic pollution — but few people know it even exists. In this episode of Raw Green, Francesco and Emma speak with Hanson Cheng and Siobhan Anderson from The Tyre Collective (thetyrecollective.com), a team developing innovative technology to capture tyre particulate matter directly at the source.

We explore why tyre dust matters for air quality, water quality, public health, and sustainability, and how smart design and engineering can help cities across Europe and beyond reduce environmental impact. A hopeful look at a hidden pollution problem — and the people working to solve it.

Key takeaways:

• Tire wear contributes significantly to microplastic pollution.

• The Tire Collective aims to capture tire pollution at the source using electrostatics.

• Regulatory frameworks are beginning to address tire pollution in Europe and the US.

• Driving style can significantly impact tire wear and pollution levels.

• There is a growing awareness of the health impacts of microplastics from tire wear.

• Consumer awareness and labeling of tire pollution are on the horizon with Euro7 regulations.

• Collaboration between tire manufacturers, regulators, and technology developers is essential.

• Future solutions may include better tire materials and improved vehicle designs.
