Research project
tireX+ - Reduction of tyre abrasion emissions
During a one-year field trial, UMTEC is investigating and optimizing the separation system developed in the preliminary project for the removal of tire abrasion from road runoff. Due to its space-saving design, the system is particularly well-suited for use in urban areas. To assess its efficiency and cost-effectiveness in practical everyday use, an intersection in the city of St. Gallen has been equipped with the separation system. The facility will be regularly sampled and evaluated over a period of twelve months.
In Switzerland, approximately 13,600 tons of tire abrasion are generated annually. Tire abrasion is thus considered one of the largest sources of microplastic entering the environment. Due to its large specific surface area, microplastic can adsorb pollutants and release them again after being ingested by organisms. However, due to its composition, tire abrasion itself contains numerous environmentally problematic substances.
The federal government is pursuing the measure M03 "Research on improved retention of tire abrasion in urban areas" from the Federal Council report on Postulate 19.3559, aiming to develop new technical solutions to prevent the discharge of tire abrasion — particularly through road runoff. The Federal Roads Office (ASTRA) is leading this effort, promoting relevant projects through road research. Against this backdrop, UMTEC has developed an innovative separation system that specifically retains tire abrasion without incurring additional operating costs.
