Advancing a Circular Economy for Upcycling PET/PUR wastes

The inevitability to shift to a closed-loop or a circular economic model has never been more critical as the present time. The linear economic system that held sway for almost a century, casting off valuable resources to languish in landfills is rapidly running out its practicality. The concept of implementing a circular economy perhaps represents the most meaningful reform for global commerce; arguably similar in importance and impact that the industrial revolution had in the 19th century. Rampf Group and others have developed pragmatic technological solutions to address this challenge. The Rampf technique can effectively upcycle waste feedstocks by efficiently converting them to polyols that are comparable in performance to those obtained from virgin feedstocks. The technique essentially eliminates the concept of waste and keeps materials in circulation at their optimal and highest use. Several real-world case studies are presented. These include the upcycling of our in-house polyurethane (PUR) tooling board wastes, TPU elastomers, as well discarded PIR/PUR foams and polyethylene terephthalate (PET) fibers received from Tier-One suppliers. The goal has been to demonstrate how this technology might assist the successful conversion of waste feedstocks and upcycling them to form polyols for use in formulations to produce products, preventing their journey to a landfill.
