Siemens Gamesa’s first recyclable blades are spinning on a wind turbine at the Kaskasi offshore wind farm in Germany. It is the first commercial installation of recyclable wind turbine technology. The Spanish-German wind engineering giant calls its recyclable blade technology RecyclableBlade. Wind turbine blades are made of a number of materials embedded in resin.
Siemens Gamesa explains, “Separating the resin, fiberglass, and wood, among others, is achieved through using a mild acid solution. The materials can then go into the circular economy, creating new products like suitcases or flat-screen casings without the need to call on more raw resources.”
The RecyclableBlade technology was developed in Aalborg, Denmark, and the blades were manufactured in Hull in the UK (pictured above). The nacelles were produced and installed in Cuxhaven, Germany. Siemens Gamesa has a plan to make all of its wind turbine blades fully recyclable by 2030 and all of its wind turbines fully recyclable by 2040.
