Led by HTWK Leipzig, Blade2Poly aims to recover glass fibre from end-of-life wind blades and use it in new PP/PA-based injection-moulding materials.
Short answer
Blade2Poly is an R&D project aiming to convert glass-fibre-reinforced thermoset composites from end-of-life wind-turbine blades into higher-value secondary feedstocks.
Why does it matter?
Wind blades combine glass fibre, thermoset resin, core and coating layers. This architecture delivers durability but makes clean separation at end of life difficult.
Verified project scope
According to HTWK Leipzig’s announcement of 18 September 2026, the project runs from June 2026 to January 2029.
- Material characterisation and classification
- Mechanical preparation and controlled material flow
- Combining recovered glass fibre with recycled PP/PA
- Developing PCR high-performance polymers for injection moulding
- Investigating an alternative use for separated thermoset-resin fraction
What it means for composite manufacturers
The news shows that material selection increasingly includes production performance, cutting waste, traceability and end-of-life routes. The project remains in R&D; its aims must not be read as commercial product performance.
Frequently asked questions
Does Blade2Poly turn old blades directly into new blades?
No. The stated target is to use recovered glass fibre with recycled PP/PA in new injection-moulding materials.
When is the project due to finish?
HTWK Leipzig lists the planned period as June 2026–January 2029.
