Pyrolysis of Plastic Waste: Recycling Hard-to-Recycle Plastics (2023)


Summary: This fact sheet defines pyrolysis of waste plastics: the basics, the products, the processes, the technologies, advantages, and challenges. It also highlights how pyrolysis integrates into the current production of plastics, promoting a circular economy. One of the main sections of the fact sheet focuses on differentiating pyrolysis from incineration both technically and environmentally. The fact sheet finishes by presenting safety considerations of pyrolysis and a summary of the environmental benefits vs. current linear economy of waste plastics.
