Publication number: 20210229107Abstract: Generally described, the methods disclosed herein for recycling fiber composite source objects, such as wind turbine blades, include converting a whole wind turbine blade to an output material state that is useful for manufacturing other products, such as those used in construction of buildings, packaging, raw materials, and pellets, among other products. The recycling process is performed while tracking the progress and location of each wind turbine blade such that the direct source of the output material may be determined. In some embodiments, the method includes sectioning the wind turbine blades, crushing the wind turbine blade sections, tracking the progress of each blade through the process, and loading output materials into a suitable transportation vessel.Type: ApplicationFiled: March 22, 2021Publication date: July 29, 2021Applicant: GFSI GROUP LLCInventors: Don Lilly, Ronald Albrecht

Publication number: 20190070680Abstract: Generally described, the systems and methods disclosed in herein relate to sectioning an object with a frame-mounted wire saw as the step of a method for recycling fiber composite source objects, such as wind turbine blades. The frame-mounted wire saw generally includes a support frame assembly and a pulley system for directing an abrasive wire from a wire saw. A pair of slidable pulleys directs the abrasive wire through the object as the abrasive wire cuts. In some examples, the frame-mounted wire saw includes a mobility system to allow the assembly to travel along the length of the object and position the frame-mounted wire saw for the cut.Type: ApplicationFiled: October 31, 2018Publication date: March 7, 2019Applicant: GFSI GROUP LLCInventors: Don Lilly, James Longacre
