- Siemens Gamesa has launched the RecyclableBlade, the world’s first wind turbine blade that can be recycled at the end of its lifecycle.
- The first six RecyclableBlades have already come off the production line at Siemens Gamesa’s blade manufacturing plant in Aalborg, Denmark.
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.
The first six 81-meter long RecyclableBlades have been produced at the Siemens Gamesa blade factory in Aalborg, Denmark.
“The time to tackle climate emergency is now, and we need to do it in a holistic way. In pioneering wind circularity – where elements contribute to a circular economy of the wind industry – we have reached a major milestone in a society that puts care for the environment at its heart. The RecyclableBlade is another tangible example of how Siemens Gamesa is leading technological development in the wind industry,” states Andreas Nauen, CEO of Siemens Gamesa.
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.
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 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.
“Our aspiration is to produce wind turbines that can generate renewable electricity for 20-30 years. When they reach the end of their useful life, we can separate the materials and use them for new relevant applications. The RecyclableBlade is a great step in that direction and well ahead of our 2040 goal,” said Gregorio Acero, Head of Quality Management & Health, Safety, and Environment at Siemens Gamesa.
