WEB How to prevent tyre wear from becoming microplastic pollution of the environment

Microplastic is a considerable environmental issue in the world nowadays. The impact on life is not clear yet. It is in the Waters and in the soils, meanwhile also in plants, especially near motorways.

Tyre wear significantly contributes to the growing amount of microplastic in the environment. Often it is said, tyre manufacturers should produce tyres that are wear free. Unfortunately, this will mean that we are unable to brake to slow down and stop. In addition, there is the so-called magic triangle of the tyre Technology. That says that wear is in a target conflict with wet grip that means security and rolling resistance that means fuel consumption and CO2 emissions. So even if tyre wear gets significantly improved, and the tyre manufacturers are working hard on that, the problem will persist. Electromobility is even more critical with regard to tyre wear as the vehicles are much heavier due to the batteries.

But is tyre wear only troublesome and worrying waste? As long as we see it that way.

In this lecture it will be shown what potential tyre wear bears and how we can proceed with it in order to reduce significantly or even avoid microplastic load in the environment. Different ways for reuse and recycling will be proposed and the challenges related to them addressed. But also some hints how can we, every one of us, contribute to reducing the microplastic emissions via tyre wear will be given.
