Join us at 6PM on Thursday, February 24 at the Mount St Joseph Theater Lobby for "Dissolution Recycling of Polyolefins Using Alkane Solvents" presented by John M. Layman. John is currently a Senior Director in Corporate R&D at The Procter & Gamble Company (P&G). His current efforts are focused on helping P&G develop more environmentally responsible product choices that help consumers and industry reduce overall environmental impact. He earned his Ph.D. in Macromolecular Science and Engineering from Virginia Tech and his B.S. in Chemical Engineering from Virginia Commonwealth University.

Abstract - Consumers increasingly expect and demand sustainable products without trade-offs in performance or cost. Concerned companies, like P&G, have established long-term sustainability goals that include the use of large percentages of recycled resins in their products and packaging. To satisfy consumers’ expectations and achieve companies’ goals, P&G has developed a novel purification technology that converts contaminated recycled polyolefins (PP and PE) into virgin-like resins.

The dissolution recycling technology purifies recovered polyolefins using an alkane solvent at elevated temperature and pressure, and a combination of standard chemical engineering unit operations, such as liquid–liquid extraction, sedimentation, size exclusion and adsorbent filtrations, and devolatilization. These processes remove pigments, odor, volatile organic chemicals, and other organic and particulate contaminants and additives rendering a material with virgin-like color and appearance.
