A snapshot of innovation activity and market participants in CFRP recycling

The growing adoption of carbon fibers, increasing production capacities, and decreasing manufacturing costs have significantly elevated the importance of recycling carbon fibers (CF) and CF-reinforced plastics (CFRP). In this emerging market, the intellectual property (IP) landscape has undergone substantial changes over the past two decades.

As the CFRP market matures and continues to grow, sustainability issues, particularly the circular economy and the creation of “second-life” products, have moved to the forefront. These developments are clearly reflected in patent filing data: since 2010, this technology sector has
experienced a remarkable annual growth rate of 13.6 % (CAGR) in patent filings.

Dynamic growth in the innovation landscape since 2010

An analysis of innovation activity in CFRP recycling (fig. 1) reveals a shift from a stable plateau (1) in the years before 2010 to a phase (2) of significant growth. Notably, this momentum has continued beyond 2022, indicating sustained innovation activity. A closer examination of the portfolios of major players shows how they are striving to define their positions in this emerging
market.

Market players and their strategies: an innovation-market matrix analysis

The patent landscape analysis (fig. 2) provides fascinating insights into the strategies and technological priorities of key market players. Clear differences in approaches and targeted positioning become evident.

Sinopec, one of the largest filers in this domain, focuses heavily on pyrolysis processes and the development of catalysts for this technology. Additionally, recycled materials are being advanced as raw materials for new products. In contrast, Mitsubishi Chemical pursues a different strategy: its focus lies in developing new CFRP products made from reclaimed fibers.

Toyota also plays a central role. As a leading automotive manufacturer in CFRP recycling, the company is building a growing patent portfolio for processes and recycled fibers specifically optimized for automotive applications.

In Germany, a similar trend can be observed: automotive companies are focusing on integrating
recycled fibers into their production processes and advancing fiber recovery from used materials. In the field of direct fiber recovery, research institutes such as Fraunhofer are shaping the field with high patenting activity and the development of novel technologies. Emerging technologies such as thermoplastic CFRP could offer new market entrants opportunities to position themselves in this rapidly growing technological field.
