Iowa plant turns retired wind turbine blades into fibres and powders for roads
Regen Fiber has opened a wind turbine blade recycling facility in Fairfax, Iowa, using an all-mechanical process that avoids heat and chemicals. The plant shreds old blades into fibres and additives for use in concrete, mortar and asphalt. It expects to process more than 30,000 tons of blades each year.
Wind turbine blades pose a challenge at the end of their lifespan, requiring recycling. Regen Fiber, a facility in Fairfax, Iowa, USA, opened in 2024 and began processing retired blades. The company employs an all-mechanical recycling process, distinguishing it from methods using heat or chemicals. This process mechanically breaks down the blades, recovering materials for industrial applications, such as concrete, mortar, and asphalt.
Fairfax facility is expected to process over 30,000 tons of blades annually. The recycled materials, including fibres and additives, enhance the durability and environmental resistance of construction materials. The company operates similar facilities in Des Moines, Iowa, and Lubbock, Texas, each handling specific blade materials.
