Turning Wind Turbine Blades into Reinforcement Fibers: REGEN Fiber Featured in Power Up Iowa Segment

Turning Wind Turbine Blades into High-Performance Fiber

As the wind energy industry continues to expand, one major sustainability challenge remains: how to manage wind turbine blades at the end of their service life. 

Traditionally, many blades have ended up in landfills or are burned – both options bringing environmental concerns for an otherwise clean source of energy. At REGEN Fiber, we are working to address this issue through our patented recycling process that transforms decommissioned wind turbine blades into reinforcement fibers being used today in construction projects. 

Our fibers can be used in a range of applications, including: 

• Concrete 
• Asphalt 
• Composites 

Our work was recently highlighted in a video segment from Power Up Iowa, where Travero President Lisha Coffey shared the story of how REGEN Fiber is contributing to a circular economy while delivering performance benefits across multiple industries. 

Watch the segment: 

A Scalable Circular Solution 

As highlighted in the video, our process repurposes end-of-life wind turbine blades that would otherwise become a waste stream by transforming the materials into reinforcement fibers that help concrete, asphalt and composites last longer. 

Recent applications include: 

• Concrete pavements 
• Bridge columns and pillars 
• Asphalt pavements 

And the list continues to grow. 

“Every day we get a new phone call about something new this material can be used for,” Lisha Coffey notes in the video. 

This solution is not limited to Iowa. It offers a scalable approach that can be applied in other regions where wind energy infrastructure is reaching its end of life. 

Supporting Real-World Projects 

REGEN Fiber products are already in use on active job sites. A recent example involved a 200-cubic-yard parking lot pour for a large Midwestern utility in Wautoma, Wisconsin. 

The project incorporated REGEN Fiber E-Flex 500 fiber reinforcement and demonstrated excellent performance in mixing, pumping, placement, and finishing. The concrete maintained smooth workability throughout the process, helping crews deliver a clean, durable finish – all while supporting the project’s sustainability goals.

Building the Circular Economy into Construction Materials 

The construction industry is increasingly focused on identifying materials that reduce waste, lower embodied carbon, and improve long-term performance. Our approach supports those goals by redirecting turbine blade waste into fiber reinforcement products that enhance concrete’s durability and lifecycle value. 

As demand grows for infrastructure solutions that meet both environmental and structural requirements, recycled fibers like those produced by REGEN Fiber will continue to play a meaningful role in closing material loops and advancing the performance of modern concrete systems.
