Workshop 4: Advancing Circular Solutions for Wind Turbine Composites

28 January 2026

At the Composite Circle workshop in beautiful Riga, Latvia, experts from the Baltics and Nordics came together to explore the full lifecycle of composite materials; from dismantling and waste handling to recycling such as co‑processing in cement kilns, laboratory‑scale solvolysis, and the potential for creating new composite materials. The discussions bridged policy, technology, and practical realities, highlighting what can already be done and what we can achieve through coordinated action.

A key theme was the need for a more comprehensive understanding of the quality, volume, and cost factors related to composite waste recycling. Participants emphasized that consistent material flows, clear legal requirements, and well‑defined responsibilities across the value chain are essential for building a functional and economically viable recycling ecosystem. This includes harmonized guidelines for dismantling, logistics, pre-processing steps such as on-site shredding, and preparation of material streams for processes like cement co‑processing.

Our shared vision is to accelerate a circular transition where composite materials from the energy sector are not treated as waste, but as valuable resources – supporting new industries, reducing environmental impact, and strengthening cross‑border cooperation. Realizing this vision requires aligned regulation, reliable recycling technologies, and committed collaboration across the entire value chain. This work is made possible with the support of Interreg Baltic Sea Region.
