PureCycle Technologies, Inc. is commercializing a patented purification recycling technology (the Technology), originally developed by The Procter & Gamble Company, for restoring waste polypropylene into resin with near-virgin characteristics, called ultra-pure recycled (UPR) resin. Its process includes two steps: Feed Pre-Processing (Feed PreP) and the use of the Technology for purification. The Feed PreP step will collect, sort, and prepare polypropylene waste (feedstock) for purification. The purification step is a purification recycling process that uses a combination of solvent, temperature, and pressure to return the feedstock to near-virgin condition through a novel configuration of commercially available equipment and unit operations. The purification process puts the plastic through a physical extraction process using critical fluids that both extract and filter out contaminants and purify the color, opacity, and odor of the plastic without changing the bonds of the polymer.
