Join the circular Economy

Powerful Past. Revolutionary Future.

REGEN Fiber products are made from retired wind turbine blades using our patented process with no heat and no chemicals. We’re turning yesterday’s wind energy into tomorrow’s stronger, longer-lasting infrastructure.

Instead of sending old blades to landfills, we transform them into high-performance additives that make concrete, asphalt, composites and other materials stronger. Join the circular economy movement and build better while reducing waste and embodied carbon.

REGEN Fiber transforms end-of-life wind turbine blades into 100% recycled fiber additives that strengthen concrete, asphalt and composites, making your projects more sustainable and durable.

Our Sustainability Difference

From Wind Energy TO CONSTRUCTION

Those turbine blades that captured wind power for decades are incredibly strong and durable. Now we’re giving that strength a second life in your projects.

REGEN Fiber mixes evenly without balling up and can replace wire mesh in many applications. This means faster pours, safer job sites (no mesh to trip over), and smoother finishing.

For sustainability leaders: REGEN Fiber closes the loop on wind power. We transform what was cradle-to-grave waste into cradle-to-reuse value, solving wind energy’s sustainability gap. A commitment to clean energy can now extend through the entire lifecycle.

Yesterday’s wind energy becomes tomorrow’s stronger infrastructure. That’s the circular economy in action.

Level up with REGEN Fiber for safer crews, faster completion and better, more cost-effective results.

DELIVERING VALUE ACROSS THE BOARD

Wind Energy:

Responsible disposal solution

Wind turbines generate clean power for 20-25 years, but retiring their massive blades has been a major challenge. REGEN Fiber transforms these blades into valuable construction materials instead of landfilling or incinerating them. We’re helping the wind industry stay green from start to restart.

Construction:

Better Materials

Our recycled fiber products make concrete and asphalt stronger while reducing cracks and extending lifecycles. They mix better than conventional fibers—no balling up, no poking up through finished surfaces. Build better projects with materials that deliver standout benefits and save you time.

Communities:

Reduced Landfill Burden

Every blade we recycle saves valuable landfill space, and these blades are huge. By transforming waste into sought-after products, we’re helping communities preserve land for better uses. It’s local environmental action with real impact.

Environment:

Less Embodied Carbon

Using REGEN Fiber cuts embodied carbon in your projects by replacing virgin materials with recycled content. Plus, our patented process uses no heat or chemicals, just mechanical recycling. Every project using REGEN Fiber is a step toward net-zero construction.

Economy:

American And Local Jobs

Stay competitive by reducing labor and material costs while delivering superior project outcomes. Contractors using REGEN Fiber gain distinct advantage by offering cost-effective, high quality, and environmentally responsible solutions that meet modern market demands.

FAQ

Does REGEN Fiber cost more than virgin fibers?

heREGEN Fiber is cost-competitive with other reinforcement fibers. When choosing reinforcement options, when it comes to REGEN Fiber, you do not have to pay a premium for a 100% recycled, sustainable option.

What is REGEN Fiber and how is it produced?

REGEN Fiber is an innovative line of products made from recycled wind turbine blades and from virgin scrap materials from new blade manufacturing. Using a patented, all-mechanical process, we break down end-of-life blades into reinforcement fibers and additives without heat or chemicals. This sustainable solution not only addresses the environmental challenge of wind turbine blade disposal but also produces high-performance fiber reinforcement materials for concrete, asphalt and composite applications.

How does REGEN Fiber enhance concrete and asphalt performance?

REGEN Fiber’s E-Flex product line helps extend the life of concrete and asphalt. When incorporated into these materials, they:

• Reduce plastic shrinkage in concrete, resulting in less concrete cracking.
• Strengthens concrete and asphalt to reduce wear and tear.
• Enhance surface durability of concrete.
• Reduces potholes and cracking on asphalt.
• Boosts freeze thaw resistance.

These enhancements lead to longer-lasting infrastructure and lower maintenance costs, while using a 100% recycled material that helps a project’s carbon footprint. 

Is REGEN Fiber compatible with standard construction practices?

REGEN Fiber products are designed to integrate into existing concrete and asphalt mixing processes. Our team provides comprehensive support to ensure smooth adoption, including:

• Dosing assistance: Helping you get the right dosage for your application.
• Technical support: Offering hands-on help during implementation.

How does using REGEN Fiber help me avoid tariffs?

REGEN Fiber products are made in the USA using domestic and global materials. This means that overseas shipping and tariffs don’t apply, saving you time and additional fees.
