Title: Innovations in Recycling: The Contributions of Wei Kong

Introduction

Wei Kong is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of recycling, particularly in the development of high-quality recycled polyethylene terephthalate (rPET) pellets. His innovative approach addresses the challenges associated with recycling PET materials, making a positive impact on sustainability.

Latest Patents

Wei Kong holds a patent for the "Preparation of recycled polyethylene terephthalate pellets, and bottles formed therefrom." This method involves recycling polyethylene terephthalate by obtaining flakes that are re-polymerized using heat and/or a chain extender combined with an anti-yellowing agent. The process yields an average molecular weight of at least 40,000 Da and a tunable intrinsic viscosity of approximately 0.5 dl/g to 0.8 dl/g. The resulting rPET pellets exhibit a color deviation of approximately 2.5 or less from the re-polymerized 100 percent post-consumer polyethylene terephthalate flakes. This innovation allows for the production of PET bottles with 100% post-consumer recycled content and supports multiple recycling cycles.
