September 7 (Renewables Now) - Siemens Gamesa Renewable Energy SA (BME:SGRE) on Tuesday announced that it has manufactured the world’s first recyclable wind turbine blades for commercial use in offshore wind projects.

The first six 81-metre long pieces came out of Siemens Gamesa’s blade factory in Aalborg, Denmark.

The blades are made from a combination of materials cast with a special kind of resin, which has such chemical structure that enables the components to be efficiently separated once the blade reaches the end of its life cycle, the turbine maker explained.

The separation from the resin is a mild process that protects the properties of the materials in the blade, ensuring that they can be reused in new applications.

Three customers have already committed to using the recyclable blades for their offshore wind projects, Siemens Gamesa said.

RWE Renewables will be the first to install the blade, and monitor it with Siemens Gamesa, at its Kaskasi offshore wind farm in German waters.

France’s EDF Renewables and German developer Wpd AG are working with Siemens Gamesa to incorporate sets of recyclable blades into their future offshore wind projects.

This summer, Siemens Gamesa unveiled its new Sustainability Vision, in which it set a goal to manufacture fully recyclable blades by 2030, and put a 100% recyclable turbine on the market by 2040.
