A groundbreaking recycling center in Fairfax is set to revolutionize the disposal of decommissioned wind turbine blades, marking a significant stride toward sustainability. Owned by Alliant Energy subsidiary Travero, REGEN Fiber hosted its grand opening with a mission to divert waste from landfills and produce materials for construction reinforcement.

Travero President Lisha Coffey highlighted the longstanding challenge of recycling wind turbine blades due to their large size and complex composition, which includes wood, foam, metals, and epoxy-laden fiberglass. However, REGEN Fiber has cracked the code by employing a mechanical process that eschews chemicals or heat, capable of handling up to 12 tons of material per hour.

How is it recycled?

Upon arrival at the facility, decommissioned blades, already reduced to sizable chunks, undergo further dismantling through a series of mills and drums in a proprietary process. The specifics of this process are closely guarded, with guests required to leave their cell phones behind to protect the technology's secrecy.

Different grates are utilized to sort the materials into various sizes tailored to specific applications, ensuring versatility in their potential uses. Safety measures are paramount, with systems in place to suppress sparks and prevent the release of harmful fiberglass particles into the air, safeguarding the well-being of employees.

The facility goes above and beyond

 The facility goes above and beyond by capturing dust, a byproduct that could potentially be sold alongside other products for enhancing the performance of concrete, mortar, or asphalt. Jeff Woods, the business development director for Travero, noted promising early studies demonstrating that the fibers extracted from wind turbine blades strengthen concrete while reducing cracking and shrinking.

Officials from the Iowa Department of Transportation expressed interest in incorporating the product into future road projects, although they seek further details on ongoing research. With wind turbine blades typically lasting around 20 years, Alliant Energy, the parent company of Travero and REGEN Energy, is preparing for their eventual decommissioning.

While Alliant's wind farms in Iowa are still operational, spokesman Morgan Hawk emphasized REGEN Fiber as a future recycling solution. Fairfax Mayor Jo Ann Beer echoed this sentiment, expressing enthusiasm for the economic and sustainable opportunities presented by Travero and REGEN Fiber's presence in the city.

Are Wind Turbines 100% Recyclable?

Fiberglass, traditionally challenging to recycle due to its non-biodegradable nature, is undergoing a transformative journey from waste to resource. Instead of languishing in landfills or being incinerated, innovative solutions are emerging to repurpose wind turbine blades, leading to a sustainable revolution in construction practices.

Engineers and scientists are pioneering methods to integrate fiberglass into cement production, a vital component in everyday construction projects. Moreover, entire turbine blades are finding new life as structural elements, serving diverse purposes from bike sheds in Denmark to noise barriers along US highways.
