Abstract: A method for recycling a used rotor blade of a wind turbine includes processing the used rotor blade into a plurality of material fragments. The method also includes treating the plurality of material fragments to remove at least a portion of the at least one composite material and expose the at least one fiber material of the used rotor blade. Further, the method includes mixing the treated plurality of material fragments with, at least, an alkali activator to form a usable geopolymer concrete.

Abstract: A system for forming an article includes a polymer resin formulation formed of a semicrystalline polymer material having a first fiber content and an amorphous polymer material having a second fiber content. The first fiber content is higher than the second fiber content. Further, the semicrystalline and amorphous polymer materials are blended together to form the polymer resin formulation having a blended fiber content of greater than 10% by weight. Moreover, the polymer resin formulation is amorphous. The system also includes a computer numeric control (CNC) device for printing and depositing the polymer resin formulation layer by layer to form the article.
