Carbon Fibre in the EU: A Victory for Sustainable Innovation

recycling

Earlier this year, the European automotive, aerospace, and engineering sectors faced a regulatory challenge that threatened to upend decades of material innovation. The European Commission proposed a revision to the End-of-Life Vehicles (ELV) Directive that included the potential classification of carbon fibre as a hazardous material. 

Why the Industry Faced a Potential Ban

The draft policy cited concerns over airborne particulate emissions from carbon fibre waste processing - particularly during mechanical shredding or improper disposal - raising fears of health risks to workers and the environment. Such a classification could have placed severe limitations on the use of carbon fibre in mass-market vehicles from 2029 onward.

However, scientific and industrial leaders responded swiftly. Researchers at Imperial College London, among others, provided clear evidence that carbon fibre is chemically inert and non-toxic in its raw, processed, and in-use forms (Pimenta  & Pinho, 2014). The real concern lies not with the material itself, but with the management of waste at end-of-life - a challenge shared by many industrial materials.

Science Proves Carbon Fibre Is Not Hazardous

Carbon fibre’s perceived risks are linked to poorly managed waste streams, not the fibre itself. In fact, the fibre is widely regarded as safe in all operational contexts, with no scientific evidence suggesting otherwise. When carbon fibre is integrated into composites, it is fully encapsulated in resins that prevent any particle release under normal use conditions.

Industrial studies and life-cycle assessments have further demonstrated that the environmental performance of carbon fibre is superior to metals like steel or aluminium when used to reduce vehicle weight and emissions in service (Witik et al., 2013). The environmental payoff of lightweighting far outweighs the energy-intensive production phase - provided the material is responsibly recycled rather than landfilled.

Recycling Is Already a Reality, Not a Future Concept

A key factor in securing carbon fibre’s regulatory future has been the growing maturity of recycling technologies. Industry players have made significant strides in scaling up processes that recover high-quality fibres for reuse in new applications.

One of the most widely adopted methods is pyrolysis, where carbon fibre reinforced polymers (CFRPs) are heated in an oxygen-free environment to break down the polymer matrix, leaving the carbon fibres intact. This technique has been shown in laboratory conditions to retain 80–95% of the mechanical performance of individual fibres (Heil et al., 2009). However, when processed into traditional discontinuous felt or mat forms, composite performance typically suffers a much greater reduction - often around 70% compared to virgin woven fabrics. This performance gap is driving innovations by companies such as Gen 2 Carbon and Lineat (Bristol, UK), who are pioneering methods to re-align recycled fibres into tapes or continuous formats that retain significantly higher composite mechanical properties.

Another method, the fluidised bed process, developed at the University of Nottingham, uses hot air to combust the  polymer matrix while separating and recovering the fibres (Yip et al., 2002). Although this process can lead to more fibre damage than pyrolysis, it excels at handling contaminated or mixed-material waste.

More advanced chemical processes, such as solvolysis using supercritical fluids, have also shown promising results. These methods use alcohols or catalysts under controlled conditions to dissolve the resin, leaving fibres with mechanical properties nearly indistinguishable from new material (Jiang et al., 2009; Pinero-Hernanz et al., 2008). While these technologies are not yet widely commercialised due to cost and scale challenges, they represent a critical  next step in advancing the circular economy for composites.

Industrial scaling, however, is already well underway. The newly opened FIB3R plant in Imola, Italy, for example, is now Europe’s largest dedicated carbon fibre recycling facility. Developed by Hera Group in partnership with the University of Bologna and Curti Costruzioni Meccaniche, FIB3R uses pyrogasification technology to process composite waste at scale. Capable of producing around 160 tonnes of recycled fibre annually, the facility marks a significant step toward  making carbon fibre recycling commercially viable and environmentally beneficial across Europe.

The Industry’s Role in Shaping the Outcome

The automotive and aerospace sectors did not stand by quietly. Organisations such as Forward Engineering and the Aircraft Fleet Recycling Association (AFRA) actively engaged with EU lawmakers, providing data, case studies, and technical evidence to challenge the draft proposal. Their efforts highlighted not only the safety of carbon fibre in use but also the industry’s commitment to developing responsible end-of-life solutions.

Collaborative projects like CIDER, led by Fraunhofer IGCV, have also played a role in demonstrating scalable, circular business models for recycled composites. These initiatives are helping to establish supply chains that make carbon fibre sustainable by design, rather than relying on wasteful disposal practices.

A Balanced Decision with a Clear Responsibility

By removing the hazardous classification from the draft directive, the EU has struck a balanced regulatory position - protecting innovation while reinforcing the industry’s obligation to scale up recycling efforts. The message is clear: carbon fibre is not the problem. Poor waste management is.

Moving forward, the challenge for engineers, manufacturers, and recyclers is to fully integrate circular economy principles into the use of carbon fibre. This means designing for disassembly, investing in recycling infrastructure, and developing products that can be remanufactured or repurposed at the end of their service life.

At DEXET, we welcome this outcome as a validation of science-driven policy and industry-wide collaboration. We remain committed to pioneering material solutions that not only perform at the highest level but also contribute to a more sustainable, circular future for engineering.
