(89e) Scale-up of Purecycle Purification Process

PureCycle uses a patented, ground-breaking recycling process to separate virtually all color, odor, and contaminants from polypropylene waste feedstock to transform it into Ultra-Pure Recycled (UPR) resin.

This presentation will outline the development of the PureCycle process from the initial concept to commercial reality. A benchtop pressure cell was used to develop the fundamental polymer solubility data that supports the overall design concept. The main unit operations for the process were developed using a lab-scale batch system. Successful operation of the pilot scale system demonstrated that the purification process can be executed continuously. The commercial scale implementation uses a modular design that will enable rapid expansion of the process to multiple sites. The key challenges and successes at each stage of development will be discussed.

At every scale, the purification process has been demonstrated to produce recycled plastic with a color and clarity equivalent to virgin material. This talk will also introduce the next steps for the growth of PureCycle. Future areas of research and optimization will also be discussed.
