Recycling initiative gives skis a second life in Austria

Winter sports gear, particularly skis and boots, are a massive industry in Austria, with hundreds of thousands of pairs sold annually. However, these high-tech products often end up in landfills at the end of their lifespan, wasting valuable resources. The "WINTRUST" research project, based at the Montan University of Leoben, is tackling this issue by developing systematic recycling methods for winter sports equipment.

Recycling this gear presents significant challenges. Skis, boots, and helmets are made from diverse components and materials that are difficult to separate. Skis, for instance, are constructed from an inseparable composite of various materials that must be broken down for effective recycling. The sheer volume of discarded equipment is also substantial, with hundreds of thousands of pairs of skis alone sold in Austria each year, and millions globally.

The "WINTRUST" project brings together 30 companies, institutions, municipalities, and research facilities to find solutions. In the model region of Pinzgau-Pongau, a close collaboration has been formed with sports retailers, local governments, and waste management associations. "After collection, the material must be separated into individual groups, such as skis, poles, and boots, as joint processing is not possible," explained David Zidar, the scientific director of WINTRUST. If the project's findings are widely implemented, it could lead to the recovery of thousands, or even tens of thousands, of tons of material, reintegrating valuable resources back into the production cycle.
