Circular Plastics Technologies

Dr. Kat Knauer is a polymer scientist who has dedicated her scientific career to solving the plastic waste problem. She has a PhD in Polymer Science and Engineering from the University of Southern Mississippi and completed the BASF PhD Leadership Development Program (LDP) in 2018 before taking a Senior Scientist role in BASF s Plastics Division. Currently, Dr. Knauer is a senior researcher at the National Renewable Energy Laboratory (NREL) and the Chief Technology Officer (CTO) of the Bio-Optimized Technologies to keep Thermoplastics our of Landfills and the Environment (BOTTLE) Consortium where she is developing sustainable technologies to chemically upcycle today s existing plastic waste streams and develop new plastics for the future that are recyclable by design. Additionally, Dr. Knauer is an adjoint professor in the Chemical and Biological Engineering Department at the University of Colorado, Boulder.
