NCC Participates in EoLO-HUBs to Recycle High Value Materials from Wind Turbine Blades


The National Composites Centre is delighted to announce its participation in the European project EoLO-HUBs, which will develop innovative technologies to recycle high value materials from wind turbine blades.
End-of-Life Management of Wind Farms
Europe currently is among the global leaders in wind energy technology accounting for more than 70% of all wind power installed in the world. This meets nearly 14% of the EU’s power demand, being the second largest form of power generation in the EU.
However, the huge growth that wind energy has experienced in Europe since the 90’s is starting to pose environmental problems associated to the challenges of the end-of-life management of wind farms that have reached the end of their useful lives. The EU co-funded project EoLO-HUBs, funded with almost 10 million euros, comes to propose and demonstrate novel solutions to recycle high value materials from the wind turbine blades, developing a set of innovative composite material recycling technologies.
Wind turbines blades are made of a combination of different materials, such as wood, metallics, adhesives, coatings, and composites. The recycling of end-of-life composites is challenging due to the heterogeneity of the material (i.e., including both fibers and polymerics) and the strong adhesion between the fiber and the polymer.

Recycling Composite Materials without Downgrading
Recycling composite materials frequently comes with the undesirable side-effect of "downgrading", resulting in a raw material with low performance and therefore a low value. As a result, most end-of-life composite is currently landfilled or incinerated.
In this context, EoLO-HUBs’ solution will provide an answer to the three main areas involved in the decommissioning and recycling of end-of-life wind turbines:
  • Decommissioning and pre-treatment of wind turbine blades, including handling, non-destructive inspection tools, cutting, shredding, and sorting.
  • Sustainable fiber reclamation processes addressing two alternative technologies: Low carbon pyrolysis and green chemistry solvolysis.
  • Upgrading processes for the recovered fibers, including both glass fiber and carbon fiber.

Furthermore, a knowledge hub will be set up by means of a digital platform. This platform will provide a circular economy framework, an overview of circular solutions for turbine blades and the organizations offering such solutions, and a toolset for sustainable business model development to enable the adoption of wind turbine blades recycling in diverse region across Europe. Development of secure material passports to provide accurate data on raw materials and design recommendations will further enhance turbine blade recycling in the future.
