Siemens Gamesa Renewables Energy (SGRE), a wind turbine manufacturer based in Spain, has produced the world’s first commercially accessible recyclable turbine blade, according to the company.
It was created in SGRE’s plant in Aalborg, Denmark, and is 81 metres in length. An sophisticated resin compound is used to glue the component materials together. Furthermore, after decommissioning a wind turbine blade, the organisation employs a mild acid solution to remove the resin from the components used in the process.
The use of mild acid solution, as opposed to other current methods of recycling typical wind turbine blades, according to an official statement from the company, helps to preserve the key qualities of the materials used in the blade. After being separated, the component material can be repurposed in a variety of different applications.
In fact, three major corporations have already placed orders for the revolutionary recyclable turbine blade, according to reports. In the future, both WPD and EDF Renewables have said that they want to use the blades in their respective project orders.
At the same time, the German energy company RWE will deploy a trial batch of the turbines at its Kaskasi offshore wind project, with the first generation of the project scheduled to begin operation in 2022.
It is important to note that the manufacturing technique used in the production of most wind turbines makes it impossible to recycle them profitably.
The process of manufacturing turbine blades comprises putting the materials together in a way that makes it difficult to separate them after they have been used. Moreover, because of the low cost of fresh materials, it is possible that blades will eventually find up in the waste.
It had previously been announced that the Siemens Gamesa Renewables Energy company planned to make all turbine blades completely recyclable by the end of the year 2040. SGRE’s Head of Quality Management, Gregorio Acero, stated that the company is far ahead of schedule.
Siemens Gamesa said in August of this year that it would be expanding its offshore blade plant in Hull, England by around 41,600 square metres, effectively doubling the size of its manufacturing units. According to plans, the factory, which would require a total investment of USD 256 million, will be completed by the end of 2023.
