Abstract (en)

[origin: WO2019079823A1] A method of recycling wind turbine blades includes cutting whole wind turbine blades into pieces; crushing or shredding the cut pieces to produce particles; bagging the particles; and unloading the bags into a hopper fitted with an auger to deliver the particles a transportation vehicle. A movable wire-saw system is also provided that enables automated and expedited cutting of wind turbine blades as part of the recycling process. In one aspect the wire-saw system is mounted on rails configured to move the wire-saw along the length of a wind-turbine blade. In another aspect a wire-saw is mounted onto a skid loader so as to mobilize the wire saw further and provide improved flexibility in cutting wind-turbine blades in different locations, different elevations, and with improved precision.
