Can you convert discarded fibreglass-reinforced composites into new high-grade raw materials?
More and more wind turbines are approaching the end of their useful life, after which they are dismantled and recycled. The vast majority of windmill parts can be recycled just fine, but the turbine blades are made of fibreglass-reinforced composite and are difficult to recycle with available technologies.
Strict EU rules prevent the disposal of the turbine blades in landfills, while incinerating the blades in kilns used to make cement or power plants is rather inefficient and polluting.
We expect several thousand wind turbines to be decommissioned in the coming years, which means that 500 to 1,000 tonnes of composites will have to be processed every month.
The reduction and separation of composites, copper wires, steel and wood will mark an important step, but the main challenge is recycling the composites into valuable products.
What are we looking for?
We must be able to use the product created thanks to the new recycling method for new, high-grade applications. We are looking for a solution that can handle large volumes of at least 500 tonnes per month.
The new method should be fully operational by 2025 at the latest, but earlier is better, of course. The ideal location for this new solution is our site in Vlissingen-Oost, where we have already carried out market studies into the end-of-life-cycle vision of wind farm owners. We have also conducted shredder pilots with equipment generally used to recycle wood, but this failed to produce the desired result.
Small-scale tests are currently taking place worldwide with:
- Mechanical recycling, where the composites are ground into powder for the cement industry. (Low-grade application.)
- Chemical recycling to dissolve the resin and recover the fibres.
- Thermal recycling to recover fibres through pyrolysis.
What aren’t we looking for?
We are not looking for low-grade solutions, such as crushing or incineration, in which the material’s origin properties are lost. Reusing the turbine blades as they are now is also beyond the scope of this challenge. Participants will not have to engage with the wind turbine owners, we will take care of all talks and negotiations.
What’s in it for you?
A workable, new method would have tremendous potential. Every year, tens of thousands of tonnes of composites are expected to be made available for processing. In addition, there are spin-off opportunities in other sectors (e.g., boats, automotive) that need to process composite residuals.
We have a budget for any project that will lead to a workable solution to this challenge. We can offer practical and financial assistance in setting up a test/production location at our site in Vlissingen-Oost. If additional expertise is required, we can call upon our network of suppliers and partners. We are open to collaborating with educational and knowledge institutions.
If the pilot is successful, applicants can expect follow-up projects and close cooperation.

- Coaching and counselling
- A stage and free publicity
- Knowledge and contact with experts
- Access to a network of potential partners & customers, resources and research facilities
The BioVoice programme
BioVoice is an initiative of REWIN West-Brabant, Green Chemistry Campus, the joint Rabobanks of Southwest Netherlands and the province of North Brabant. Dockwize, Impuls Zeeland, Centre of Expertise Biobased Economy and Midpoint Brabant have also joined as implementation partners. Together, we want to give innovative entrepreneurs and up-and-coming biobased/circular talents the space and opportunities to develop and market their idea/product, so as to achieve our common goal: accelerating the transition to a sustainable economy.
BioVoice is made possible by financial contributions from the Regional Deal for Central and Western Brabant, the Province of North Brabant, the Province of Zeeland and Rabobank.
Conditions of participation
We are initially looking for a method that will allow us to process large quantities of material. This method should be suitable for scaling up to 500 tonnes per month in a reasonable period of time, and ultimately up to 1,000 tonnes per month.
Your pitch (max 6 pages / 18 slides)
- Concept description: Describe your concept in as much detail as possible.
- Pilot description: Please provide a brief description of what it will take to prototype and/or pilot and what you will need from us to do so.
