Siemens Gamesa launch of world’s first recyclable wind turbine blade for commercial use offshore

Siemens Gamesa presenta la primera pala reciclable del mundo

Siemens Gamesa launches the RecyclableBlade, the world’s first wind turbine blade that can be recycled at the end of its lifecycle. This breakthrough is a crucial step towards Siemens Gamesa’s ambitious goal to make turbines fully recyclable by 2040.

Wind power is one of the cornerstones in the quest to tackle the climate emergency. With more than 200 GW of new offshore capacity projected by the Global Wind Energy Council to be installed by 2030, it is critical to quickly introduce recyclable solutions. Siemens Gamesa is leading the way for a sustainable future with the RecyclableBlade, the world’s first 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 and thereby defines the next milestone in sustainability.

Many components of a wind turbine, such as the tower and nacelle components have established recycling practices. Until now, the composite materials used in wind turbine blades have been more challenging to recycle. Built on proven, reliable processes, the Siemens Gamesa RecyclableBlade breaks this mould and is the first of its kind, enabling recycling at the end of its lifecycle, and sets the path to a future where the full recyclability of projects will be a market requirement.

The chemical structure of this new resin type makes it possible to efficiently 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, in contrast to other existing ways of recycling conventional wind turbine blades. The materials can then be reused in new applications after separation.

Siemens Gamesa offshore customers will now have the unique possibility to choose the RecyclableBlade as an option for their future projects

First six RecyclableBlades already produced at Siemens Gamesa’s blade manufacturing plant in Aalborg, Denmark. Siemens Gamesa has already reached agreements with 3 of its major customers: Siemens Gamesa is working closely with RWE to install and pilot the innovative recyclable blades at the Kaskasi offshore wind power plant in Germany for the first time; with EDF Renewables with the aim to deploy several sets of RecyclableBlade at a future offshore project; with wpd with the intention to install sets of the RecyclableBlade at one of their future offshore wind power plants.

Fully recyclable wind turbine by 2040

Siemens Gamesa recently launched an ambitious Sustainability Vision towards 2040, pushing the boundaries of sustainability to create a better future for generations to come. Under this umbrella, the company announced an ambitious goal to make turbines fully recyclable by 2040.
