New results from the DecomBlades innovation project proofs that glass fibre retrieved from wind turbine blades can be processed and melted to high-quality fibre qualifying to be used in new wind turbine blades. Proving this way of using recovered glass fibres is a real breakthrough on the path to a circular wind industry.
For 20 years, private companies and research scientists have experimented with recycling blades from wind turbines that have reached the end-of-life. Now, a huge progress is being made to find recycling paths for the necessary quantities of blades, as more and more wind turbines are decommissioned.
Using the largescale pyrolysis test plant developed by MAKEEN Energy, the consortium behind the DecomBlades innovation project has succeeded in extracting and processing the principal component – glass fibres – from retired 37-metre wind turbine blades to such a high quality that the material can be melted and used in the production of new wind turbine blades.
“At first attempt, we have succeeded in recovering and processing glass fibre that is suitable for inclusion in the raw material mix on a par with virgin material in the extremely sensitive glass fibre production process. We have achieved this important milestone not at laboratory scale, but at an industrial level. The process has real commercial prospects. It’s incredibly exciting to have reached this point,” says Irene Bach Velling Villadsen, Project Manager at MAKEEN Energy, the company that has developed the pyrolysis technology used in the process.

DecomBlades completes the cycle for old wind turbine blades
MAKEEN Energy's division EnviroTech is part of this new project that aims to lead the way to sustainable and economically viable recycling of wind turbine blades.
DecomBlades and 3B-Fibreglass are ready to unlock circular recycling of glass fibre in wind turbine blades
In collaboration with glass fibre producer 3B-Fibreglass, the DecomBlades partners are pursuing a circular route for the glass fibre from decommissioned wind turbine blades.
DecomBlades - a circular economy for wind turbine blades
The DecomBlades project seeks to form the basis for commercializing wind turbine blade recycling. We're proud to play a central role along Ørsted, Vestas, LM Wind and others. At the end of the project, we will have concept-designed a full-scale pyrolysis plant for composite materials which interested parties can order.
