The world's first wind turbine with processed blades began to supply electricity

According to estimates, by 2050 over 200,000 blades of wind turbines will have to be disposed of in the world. These are huge pieces of composite plastic about 100 metres or more long. They will never be laid out in the ground or intended for processing. Everything can change the design of Siemens Gamesa.

Siemens Gamesa expects that all parts of wind generators will be processed by 2040. Until recently, only blades could not be processed from large wind-generator components, while gondolas, parts of the generators and the tower were to be processed. Reuse of the materials from which the turbin scapulas — glass, metal and plastic — were made required to develop readily soluble resin in weak acid solutions.

The composition of such resins was developed by project partners from Aditya Birla Advance Materials and, moreover, were able to make it tougher than its normal composition, thus accelerating the blade production. After the end of the life cycle, the blade from the processed material will be sunk into a weak acid in which the resin will be completely dissolved, freeing all components of the blades for reuse.

The Siemens Gamesa subsidiary currently manufactures the 81st recycling blades of RecyclableBlades and plans to start manufacturing 108 and 115 blades. 38 wind generators with processed blades are scheduled to be installed on the shelf by the end of the year.
