Researchers at Luleå University of Technology in Sweden are studying the potential of recycling carbon fiber from discarded hockey sticks to create repair mats for wind turbine blades. These mats can serve to fix heaters that prevent turbine blades from freezing, as the carbon fiber is conductive. Professor Patrik Fernberg, a materials technology expert, explained that the mats heat up when electric current passes through them, similar to electric seat heaters in cars.

The study highlights that during operation, wind turbine blades can sustain considerable damage due to various factors, including lightning strikes or collisions with ice. Such damages may necessitate repairs to the outer shell of the blades, where the damaged material is removed and replaced with new composite material. In addition to carbon fiber, fiberglass is also mentioned as a viable option for common repair tasks, showcasing a growing interest in the sustainable use of materials in renewable energy technologies.

Overall, this research into recycling carbon fiber illustrates innovative approaches to mitigating waste in the sports equipment industry while also enhancing the efficiency and longevity of renewable energy infrastructure. The intersection of these two fields reflects a commitment to sustainability, and if implemented, it could lead to environmentally friendly practices within both sports and energy sectors.
