CompositeCircle

Workshop 3 at Krakow, Poland, 18th of September 2025

The workshop brought together researchers, companies, and authorities in beautiful Krakow to explore circular economy solutions for composite materials. The event focused on chemical recycling methods such as solvolysis, which enables the recovery of high-quality fibers from end-of-life products. Presentations and discussions emphasized the need for collaboration between technology, regulation, and industry to promote sustainable composite recycling in the Baltic Sea region.

CompositeCircle presented at Käyttö ja Kunnossapito 2025

CompositeCircle project was presented by Egidija Rainosalo from Centria UAS at Käyttö ja Kunnossapito 2025 (Operation and maintenance 2025), a Finnish national event organized by Suomen Uusiutuvat Ry (Renewables Finland) in Oulu, Finland, on 3.-4. of September 2025.

The event gathered professionals and stakeholders from across the renewable energy sector to focus on the operation and maintenance of wind power plants, solar power plants, and energy storage systems. It served as a platform for exchanging experiences, exploring new solutions, and strengthening collaboration within the industry.

CompositeCircle ongoing activities aimed at building a value chain in the Baltic Sea region for the recycling of wind turbine blades were presented. Two complementary pathways were highlighted:

– Co-processing in cement kilns, where blades can be used as alternative raw materials and energy source.
– Solvolysis technology, enabling the recovery of resins and fibers for new composite materials.

The industry emphasized challenges at the beginning of the dismantling process:

– Road maintenance to facilitate transport of large blade components at their end of life
– The need for clear guidance on dismantling processes and the actors for further processing
– On-site size reduction of blades, while ensuring effective dust control measures to avoid spreading of particles into environment

CompositeCircle project aims to address those challenges by gathering information into a guidebook. Stay tuned for further updates as we continue developing solutions for the future of renewable energy.

Kick-off at Lappeenranta 9.-12.6.2025

The kick-off meeting was held in Lappeenranta on June 9–12. Hosted by the Finnish Plastics Industries Federation and Centria, the event brought together partners from across the Baltic Sea Region to address the growing challenge of composite waste, particularly wind turbine blades.

Discussions focused on practical steps toward circular economy solutions: utilizing expertise in material handling, logistics, pilot facilities, and industrial know-how to test new methods such as solvolysis and improved waste sorting. At the same time, partners shared insights into regional strengths and how these resources could be combined into an effective system.

The meeting laid the foundation not only for technical cooperation but also for strong partnerships essential for driving change. A shared purpose and trust were reinforced, and participants committed to advancing practical pilots as well as close collaboration with industry. CompositeCircle aims to establish a functioning circular economy system that spans the entire chain—from collection and reuse to policy recommendations—with long-term impacts beyond the project’s lifetime. Workshops 1 and 2 of the project were successfully held during the meetings.
