The retreading of tires is gaining increasing importance in the transport and logistics sector as a key measure for resource conservation, CO₂ reduction, and extending product lifespan. Within the Europe-wide Azur network, over 85 partners from industry, trade, and science are working to advance the tire circular economy with innovative solutions. A significant contribution: the further development of sustainable repair methods.
"As the Azur network, we are actively committed to having more tires retreaded. Sustainable repair methods are a critical factor for the longevity of tires," says Christina Guth, network coordinator of
Azur.
The focus is on the efficient and environmentally friendly repair of the carcass – the supporting part of the tire. Especially for commercial vehicle tires, which are often retreaded multiple times, typical damages such as punctures can be remedied with modern repair techniques. An example is provided by Azur partner Rema Tip Top with the solvent-free repair patch "M-RCF 400." The system enables fast and high-quality repairs that contribute to reducing raw material consumption.
Repair and Retreading
The Pneuhage Group, operator of four retreading plants for commercial vehicle tires, also emphasizes
the importance of repair within the circular economy. Compared to the production of new tires, retreading saves up to 70 percent energy and about two-thirds of raw materials – a significant plus for the sustainability balance of fleet operators.
"Through modern repair methods, we can further improve the quality of our retreads while also meeting environmental requirements," explains Erwin Schwab, Managing Director of Pneuhage.
Since its founding in 2020, the Azur network has been pursuing the goal of fully recycling used tires as much as possible. The partners cover all areas: from
collection and repair to retreading and material or chemical recovery of old tires. Supported by scientific studies and pilot projects, the participants develop practical solutions for a future-proof tire circular economy.
Outstanding Commitment to Sustainability
For its efforts, Azur has already been honored multiple times – including with the Recircle Award in the category Circular Economy and the European Transport Award for Sustainability 2024 for a life cycle assessment study on retreading. The renewed nomination for the Recircle Award 2025 confirms the growing importance of the network as a driver of innovation
