With the introduction of a recyclable blade for onshore wind power projects, Siemens Gamesa has improved the circularity of the industry.
Launched in September 2021 and installed at RWE’s Kaskasi project in Germany in July 2022, the Siemens Gamesa RecyclableBlade for offshore was introduced to the market in just 10 months.
Customers can now use the appropriate onshore solution at their onshore wind farms. To achieve complete compatibility with the product and process requirements for onshore blades, Siemens Gamesa and partners are continuing their development work.
When a wind turbine reaches the end of its useful life, the RecyclableBlade recovery method separates the materials using a mildly acidic solution. Then, such materials can be recycled and used in many industrial applications, such as building, manufacturing consumer goods, or the automobile sector.
The wind industry had trouble with blade recycling before the RecyclableBlade was introduced. Disposal at the end of the wind turbine’s lifecycle was difficult because to the complicated fabrication process for the blades, which involved composite materials like resin, glass, and carbon fibres.
Although over 85% of a wind turbine may be recycled completely, sadly many blades were dumped in landfills after they were decommissioned.
In addition to creating the first entirely recyclable blade, Siemens Gamesa is collaborating with industry association WindEurope and other significant players in the sector to push for a landfill ban across all of Europe.
The demand for recyclable solutions is growing in importance as both onshore and offshore markets throughout the world continue to set ambitious goals for installed wind power capacity.
Finding ways to ensure the circularity of turbine blades is even more crucial as turbine diameters and, consequently, their blades, rise quickly.
CEO of Siemens Gamesa Jochen Eickholt said “Launching our RecyclableBlade for onshore sites is another outstanding achievement from our dedicated professionals. The concept was always foreseen to encompass solutions for offshore and onshore, and we’re pleased to now provide them commercially to our customers in both market segments.”
Tim Dawidowsky, COO and Chief Sustainability Officer, added “We are driving the wind industry towards full circularity with our commitment to make wind power as sustainable as it can be at every stage of its lifetime.”
“Together with our customers and our suppliers, we want wind power solutions from Siemens Gamesa to continue to help countries around the world meet their net zero carbon emission goals.”
