Title: Innovations of Donald B. Shuping in Plastic Depolymerization

Introduction

Donald B. Shuping is an accomplished inventor based in Pittsboro, NC (US). He has made significant contributions to the field of plastic depolymerization, holding a total of five patents. His innovative approaches aim to address the pressing issue of plastic waste through advanced chemical processes.

Latest Patents

One of his latest patents is a process and system for depolymerizing plastic, specifically waste polyester, into marketable monomers. This process involves a heterogeneous mixture of plastic particles, a solvent, and a catalyst that are continuously pumped through a heating zone. The flow rate is carefully controlled to maintain the plastic particles in suspension. The temperature is raised in the heating zone and maintained in a hold zone to complete the depolymerization into a homogeneous solution containing a liquefied plastic monomer. The solution is then cooled to solidify and precipitate the monomer, which is separated from the solvent for recycling. Another patent describes a continuous flow process for depolymerizing plastic, where the same principles apply to achieve a solid reaction product that can also be recycled.
