Siemens Gamesa Renevable Energy said it has produced recyclable wind turbine blades. This is the latest example of how the industry is trying to find ways to reuse materials.

In a statement, the Spanish-German engineering group claims that their recycling blades are “the world’s first recyclable wind turbine blades.” They also claim to be ready for commercial use at sea.

Siemens Games has announced that it will work with the German company RWE on the installation and management of blades at the coastal wind farm Cascasi in the North Sea of ​​Germany. Production and commercial use are expected to begin in 2022.

The company – whose main shareholder is Siemens Energy – points out that they also work with EDF Renewables. They plan to successfully install “several sets” of blades “on the future wind farm on the sea”.

A similar collaboration is taking place with WPD, a German-based company that develops and operates wind farms.

Increasing RES capacities are forcing recycling

The question of what to do with wind turbine blades when they are no longer needed is a headache for the industry. The problem is that blades made from composite materials can prove difficult to recycle. This means that many end up in landfills, when their shelf life expires.

The number of wind turbines in the world is only expected to increase as governments around the world try to increase their renewable energy capacity. And that will increase the pressure on the sector – to find sustainable solutions for disposing of blades.

Siemens Games claims that their blades can be recycled. To use a new type of resin, which “enables efficient separation of resin from other components at the end of the blade’s service life. They describe this process as “mild”. To protect “the properties of the material in the blade, unlike other existing ways of recycling conventional wind turbine blades. After separation, the materials can be reused in new production processes.

Companies are following the recycling trend

In the last few years, a large number of big players in wind energy have announced that they are trying to find an answer to the problem: What to do with wind turbine blades?

In June this year, Denmark’s Orsted said it would “reuse, recycle or recover” all turbine blades in its global portfolio of wind farms. Of course, after they are put out of operation.

That same month, General Electric’s renewable energy sector and cement maker Holcim reached an agreement to investigate wind turbine blade recycling.

It was announced back in April that cooperation between academia and industry would focus on recycling fiberglass products. This could ultimately help reduce the waste produced by wind turbine blades.

Last December, GE Renewable Energy and Veolia North America signed a “multi-year agreement” to recycle blades removed from onshore wind turbines in the United States.

And in January 2020, another wind energy giant, Vestas, said it aims to produce “waste-free” turbines by 2040.
