EUCIA President, Roberto Frassine, added: “The wind energy sector has always been at the forefront of using composites as they are instrumental to sustainable energy generation. With this collaboration we hope to set a great industry standard that ultimately will also help customers in other industries like marine and building & infrastructure.”
Learnings from wind turbine recycling will then be transferred to other markets to enhance the overall sustainability of composites.
Recycling is Crucial
In the next five years 12,000 wind turbines are expected to be decommissioned. Broadening the range of recycling options is critical for the industry’s development.
In 2018 wind energy supplied 14% of the electricity in the EU with 130,000 wind turbines and this number will only grow in the coming decades.
Wind turbines blades are made up of a composite material, which boosts the performance of wind energy by allowing lighter and longer blades. Today, 2.5 million tons of composite material are in use in the wind energy sector.
Composite Material - Background Info
Composite materials are being recycled today at commercial scale through cement co-processing, where the cement raw materials are being partially replaced by the glass fibers and fillers in the composite, and the organic fraction replaces coal as a fuel.
Through that process, the CO2 output of the cement manufacturing process can be significantly reduced (up to 16 % reduction is possible if composites represent 75 % of cement raw materials). Besides recycling through cement co-processing, alternative technologies like mechanical recycling, solvolysis and pyrolysis are being developed, ultimately providing the industry with additional solutions for end-of-life.
