Siemens Gamesa introduces RecyclableBlade, a recyclable wind turbine blades ready for commercial use offshore. With this technology, separation of the materials in the blade is possible at the end of its lifetime, enabling recycling into new applications. The first six 81-meter long RecyclableBlades have been produced at the Siemens Gamesa blade factory in Aalborg, Denmark.Siemens Gamesa is committed with RWE to install and monitor the world's first wind turbines with recyclable blades at the Kaskasi offshore wind power plant in Germany. Current plans are for the project to be producing energy from 2022 onwards. Siemens Gamesa is also working with both EDF Renewables and wpd with the aim to deploy several sets of RecyclableBlade at future offshore wind farms.
Siemens Gamesa wind turbine blades are made from a combination of materials cast together with resin to form a strong and flexible lightweight structure. The chemical structure of this new resin type makes it possible to separate the resin from the other components at end of the blade’s working life. This mild process protects the properties of the materials in the blade and the materials can then be reused in new applications after separation.
