REGEN Fiber

What REGEN Fiber does

REGEN Fiber is a private US-based materials company founded in January 2023 and headquartered in Fairfax, Iowa, that recycles end-of-life wind turbine blades and wind blade manufacturing scrap into fiber reinforcement additives sold to the construction industry. The company operates a patented all-mechanical recycling process that shreds decommissioned blades without heat or chemicals and converts 100% of the input into a portfolio of E-Flex products — E-Flex 500 and E-Flex 250 (epoxy-coated micro fibers for concrete), E-Flex Ultra Fine (microgranules for concrete, composites, and asphalt), and E-Flex GF 250 (chopped fiberglass for asphalt and bulk molding compounds). REGEN Fiber holds third-party verified Environmental Product Declarations (EPDs) across the entire product lineup under ISO 14025 and EN 15804 standards.

The company generates revenue through direct B2B sales of fiber reinforcement materials on a per-pound or per-cubic-yard dosage basis, targeting ready-mix producers, precast manufacturers, contractors, and asphalt producers across the United States. Pricing is quote-based and project-dependent, with conversion driven by direct consultation via phone (855.598.6532) and website contact forms. Named customers include Ryan Companies, King's Material, TriNorth Builders, Kraemer North America, and Travero's Logistics Park Dubuque, with documented project volumes ranging from 83 to 200 cubic yards. REGEN Fiber is a wholly-owned subsidiary of Travero, itself a subsidiary of Alliant Energy Corp, and leverages Travero's logistics infrastructure for blade collection and finished product distribution.

The company's go-to-market is sales-led, supplemented by content marketing through an on-site Knowledge Center, earned media, and membership in the National Ready Mixed Concrete Association, American Concrete Institute, Clean Power Association, and Asphalt Pavement Association. REGEN Fiber is positioned within the wind turbine blade recycling market estimated at $65 billion in 2024 and projected to reach $159 billion by 2030 at a 16.6% CAGR, with approximately 43 million tons of blade waste expected to accumulate globally by 2050 as first-generation turbines reach end of life.

Core offering

REGEN Fiber recycles end-of-life wind turbine blades and wind blade manufacturing scrap through a patented all-mechanical process (no heat, no chemicals) to manufacture fiber reinforcement additives sold under the E-Flex product line. These fibers — E-Flex 500, E-Flex 250, E-Flex Ultra Fine, and E-Flex GF 250 — are sold to ready-mix concrete producers, precast manufacturers, contractors, and asphalt producers to reinforce concrete, asphalt, and composite materials, reducing cracking, extending pavement life, and lowering embodied carbon.

Product overview

REGEN Fiber offers a unified product line of recycled reinforcement fibers made from decommissioned wind turbine blades. The portfolio consists of three core products: E-Flex 500 (micro fiber for concrete applications), E-Flex Ultra Fine (microgranules for concrete, composites, and asphalt), and E-Flex GF 250 (chopped fiberglass for asphalt and bulk molding compounds). All products use a patented all-mechanical recycling process without heat or chemicals, transforming end-of-life wind turbine blades into high-performance construction additives. The products are designed to reinforce concrete, asphalt, and composites by reducing cracking, improving durability, and extending infrastructure lifespan.

Broad incumbents

• Sika: Sika is a major producer of concrete admixtures and fiber reinforcement (including SikaFiber polypropylene fibers for concrete). Its established ready-mix relationships and global sales coverage make it the principal incumbent in the concrete-fiber category REGEN Fiber's E-Flex 500/250 competes in.
• Owens Corning: Owens Corning is a leading global manufacturer of fiberglass reinforcement for concrete, composites, and construction. As the dominant virgin-fiberglass supplier to ready-mix and composite markets, it is the primary incumbent REGEN Fiber's E-Flex GF 250 competes against, with the advantage of an entrenched specification footprint.
• Bekaert: Bekaert is the global leader in steel fiber reinforcement for concrete (Dramix). Its products are the dominant alternative to both virgin and recycled fiber reinforcement in industrial floors, pavements, and tunnel segments where REGEN Fiber targets fiber-replacement positioning.
• Veolia Environnement: Veolia operates the most established wind turbine blade recycling network globally (notably in partnership with Iberdrola in Spain). As a large waste management incumbent, it has the scale, geographic reach, and utility relationships that REGEN Fiber lacks but competes for the same blade disposal contracts.
• BASF: BASF's Master Builders Solutions division produces MasterFiber polypropylene fibers and concrete admixtures, and the company has invested in pyrolysis-based composite recycling (Carbon Fiber Recycling partnership). It is a large, R&D-rich incumbent competing in the same concrete reinforcement space REGEN Fiber addresses.

Direct peers

• Carbon Rivers: Carbon Rivers operates a mechanical recycling process for composite materials including wind turbine blades, producing recovered fiberglass and other outputs for downstream applications. It is the closest US-based direct competitor to REGEN Fiber in commercial-scale composite-to-fiber recycling.
• Global Fiberglass Solutions: GFS processes decommissioned wind turbine blades into recycled fiberglass pellets used in concrete and composite applications. It competes directly with REGEN Fiber for the same EOL blade feedstock and the same construction reinforcement end market.

Emerging players

• Aditya Birla Group (Birla Cellulose): Birla Cellulose operates one of the largest regenerated cellulosic fiber (rayon/viscose) operations globally and has invested in recycled fiber feedstock initiatives. While focused on apparel-grade fiber rather than wind blade composites, it represents the broader recycled/regenerated fiber manufacturing paradigm REGEN Fiber operates in.
• Carbon Conversions: Carbon Conversions (now part of Carbon Fiber Recycling via carbonfiberrecycling.com) uses pyrolysis to recycle carbon fiber composites into reusable reinforcement materials. It is an emerging player in composite-to-reinforcement recycling using a different (thermal) process, partially competing with REGEN Fiber's mechanical approach.

Regional players

• Vestas (Blades Recycling Initiative): Vestas, the world's largest wind turbine manufacturer, has launched CETEC and Blade Circularity initiatives to recycle end-of-life blades. As both a potential feedstock partner and a vertical competitor, Vestas influences the supply chain and end-market direction REGEN Fiber operates in, primarily in Europe.
