The first 100% recyclable wind blade

Wind power, either onshore that offshore, plays a vital role in the world’s transition to renewable energy sources. With a product lifespan of 30 years and a wind turbine recyclability rate of 85% to 90%, the wind energy industry is now trying to close the remaining gap. On March 17, 2022, the ZEBRA consortium (Zero waste Blade ReseArch) announced the production of the first 100% recyclable wind blade prototype.

The 62-meter shovel was made using resin Elius of Arkema, a thermoplastic resin well known for its recyclable properties. The material offers similar performance to thermosetting resins but with a single key advantage: recyclability.

LM Wind Power, which is part of the Zebra consortium together with Arkema, CANOE, Engie, LM Wind Power, Owens Corning etc …, will now begin large-scale structural durability tests at its center in Denmark, to verify the performance of the composite material used. The next step will be the recycling of production waste, the dismantling and recycling of this first blade and the analysis of the test results. By the end of the project in 2023, the Zebra consortium will have taken up the challenge of bringing the wind energy sector into the circular economy circuit in a sustainable way, according to the principles ofeco-design.
