Flexofibers Europa, founded in 2018 in Majadahonda near Madrid, recovers the thin, high-strength steel wire in scrap tyres and sells it as fibre to reinforce concrete. Its EIC application said that after four years of R&D it was "the very first company to have developed a production process to produce a second life steel fiber that can be used in a commercial way", with 0.25 mm fibres sorted by length to avoid clumping in concrete, according to CORDIS.
The European Innovation Council granted €2,493,059 towards a €3.56 million project from March 2023 to February 2025. The final report says the company optimised its processing line and completed "the successful engineering design and setup of our pre-industrial line", developed control software and an AI-based quality check, and field-tested the fibres with industrial customers in pavements, tunnel shotcrete and precast elements. CE marking, a life-cycle assessment and an environmental product declaration were still being pursued. In May 2024 the fibres received a European Technical Assessment, ETA 23/0933, issued through the Catalan construction institute ITeC.

Where Flexofibers Stands Now
Flexofibers Europa raised its capital in March 2025 to a subscribed €341,247, and its 2024 accounts are filed, according to Infonif. Its operating subsidiary, Flexofibers Spain, raised its capital in June 2025 and has annual sales below €500,000, Empresia reports. An environmental product declaration for the fibres is listed on the Emidat database. The company's website returned an error when checked for this article.

Flexofibers, final report to the EICThe Technology: Cleaning Wire From Tyres
Tyres contain cold-drawn steel filaments of high tensile strength. Flexofibers separates them, removes the rubber and sorts them by length and diameter into two products, the ETA says. Each tonne of new steel emits about 1.83 tonnes of CO2, the report says, so reusing tyre steel in concrete could cut emissions and dependence on imported steel.
What the EIC Project Promised, and What CORDIS Shows
The project aimed to bring the fibres to the construction market. It delivered a pre-industrial line, customer field tests and a technical assessment. The report does not give the line's capacity, tonnes produced or sales, says "minor adjustments" were still being made, and lists CE marking and patents as work in progress. CORDIS lists the project as closed.

The Money
No outside funding round has been announced. Flexofibers Europa's revenue and losses are filed but not publicly summarised, and whether the EIC Fund invested under the blended award is not public.
What Cannot Be Checked
Questions for the EIC
How many tonnes of fibre Flexofibers produces, whether the fibres now carry a CE mark, which customers buy them, and whether the EIC Fund took equity are not public.
Why Europe Should Care
Europe discards 3.7 million tonnes of tyres a year, and the report cites the construction industry's dependence on foreign supplies. Turning tyre steel into certified concrete reinforcement would close a loop the EU wants closed. The EIC funded the step to a pre-industrial line; industrial output is not yet on record.
What the project promised
Commercial second-life steel fibres from tyres for low-carbon concrete.
What the record shows
A pre-industrial line, field tests and a European Technical Assessment, with small sales and CE marking pending.
The Verdict
Certified, not scaled
Flexofibers proved its fibres meet a European assessment with EIC money. It has not shown industrial production or meaningful sales.
