Plastic Upcycling in the BOTTLE™ Consortium by Dr. Kat Knauer, Research Program Manager, National Renewable Energy Laboratory & BOTTLE Consortium



Plastic Upcycling in the BOTTLE™ Consortium

Dr. Kat Knauer

Research Program Manager,

National Renewable Energy Laboratory &  the BOTTLE Consortium

Wednesday, December 8, Webinar at 6:30 PM Pacific time


Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment (BOTTLE™) is a U.S. Department of Energy multi-organization consortium focused on developing new chemical upcycling strategies for today's plastics and redesigning tomorrow's plastics to be recyclable-by-design. This talk will introduce the BOTTLE Consortium and present several research highlights from our efforts to date including:

·     Catalytic hydrogenation of polyolefins

·     Enzymatic hydrolysis of PET

·     Upcycling PET monomers into new high-performance thermosets

·     Circular, biodegradable Polyhydroxyalkanoates

Techno-economic analysis, life cycle assessment, and supply chain modeling will also be highlighted as critical tools to ultimately facilitate the development of economical and sustainable approaches for recycling and redesigning plastics. Additionally, insights into what consumers could be doing to grow the circular economy will be presented and discussed.

Speaker Background:

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. She completed the BASF Leadership Development Program (LDP) in 2018 and placed off into a Senior Scientist role in BASF’s Plastics Division. Her research efforts focused on advanced recycling technologies which ultimately led her to leading the Materials Innovation R&D team at Novoloop (formerly BioCellection), a San Francisco Bay Area chemical recycling startup. At Novoloop she helped develop a technology that converted post-consumer polyethylene waste into valuable chemical building blocks that she upcycled into new high-performing polymer applications. Recently, Dr. Knauer joined the National Renewable Energy Laboratory (NREL) and the 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.
