EDPR pilots blade recycling
Spanish initiative uses thermochemical process on old and damaged units
EDP Renewables has signed a cooperation agreement with Spanish outfit Thermal Recycling of Composites (TRC) to implement a wind turbine blade recycling programme.
The pilot initiative will cover faulty or damaged blades that need to be replaced, as well as blades at EDPR wind farms that have reached the end of their life-cycle, the company said.
The programme will utilise a new system called R3Fiber, which was developed by TRC and the Spanish Council for Scientific Research’s National Center for Metallurgical Research.
EDPR said R3Fiber uses thermochemical transformation to convert the resins of combustible gases and liquid fuels into glass or carbon fibres that can then be reused.
“If the blades contain carbon fibres, there are no limitations on the use of composites or on the management of material, since the technology is applicable to components made from both fibreglass and carbon fibre,” the company added.
