RWE tests recyclable rotor blades


The 342 MW wind farm RWE Kaskasi will supply electricity to over 400,000 households. RWE is testing the world's first recyclable rotor blades produced by Siemens Games.

The last turbine at the RWE Kaskasi wind farm was installed 35 kilometers north of the German island of Helgoland. More than two-thirds of the wind farm's 38 turbines already supply green electricity to the grid. Kaskasi is RWE's sixth wind farm off the coast of Germany. The entire wind farm is to be commissioned by the end of the year. Then Kaskasi will be able to provide green electricity to the value of over 400,000. households per year. This is comparable to the number of households in a large city like Frankfurt am Main.

The composite materials used in the rotor blades are cast in resin, making them difficult to separate after decommissioning. Siemens Gamesa proposed a new solution. A unique feature of Siemens Gamesa RecycableBlade is the innovative resin, which is the first to separate the constituent materials from each other thanks to a special chemical structure. The separation process protects the properties of the materials, allowing them to be reused in other applications - for example in the automotive industry or in consumer goods such as suitcases and flat screen housings.
