Welcome to the Golden Gate Polymer Forum

The GGPF is a non-profit educational and scientific organization
dedicated to the study of polymeric materials and devices.

Our participants are individuals working in both industry and academia in the San Francisco Bay Area.  We sponsor monthly polymer forums, occasional symposiums or short-courses, and an email distribution list.  All interested in the study of polymers are welcome to attend.

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

Webinar

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

Abstract:

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.

Chemical Recycling of Mechanically Robust Polyacetals Synthesized by Living Cationic Ring-Opening Polymerization by Prof. Brooks Abel, UC Berkeley

Webinar

Chemical Recycling of Mechanically Robust Polyacetals Synthesized by Living Cationic Ring-Opening Polymerization

Prof. Brooks Abel

Dept. of Chemistry, UC Berkeley

Tuesday, January 18, Webinar at 6:30 PM Pacific time

Abstract:

Chemical recycling of polymers to monomer (CRM) is one of the most attractive methods to retain value in polymer materials during the recycling process. Polymers with low to moderate ceiling temperatures (Tc) are often employed in applications where recycling by depolymerization is desired. Polyacetals are a promising class of chemically recyclable polymers that exhibit a wide range of ceiling temperatures and mechanical properties that depend upon monomer structure. However, current catalyst systems for polyacetal synthesis are uncontrolled and produce polymers with low molecular weights, reducing the mechanical integrity of these materials and limiting their practical use. Furthermore, polyacetals produced by these systems often possess low thermal stabilities due to the presence of residual catalyst. To access well-defined high molecular weight polyacetals, we have developed a highly selective catalyst system that facilitates the controlled cationic ring-opening polymerization (CROP) of cyclic acetal monomers. High molecular weight polyacetals were synthesized at room temperature and possessed high thermal stability (Td > 300 °C) in the absence of catalyst. Additionally, select polyacetals exhibit mechanical properties that rival those of polyolefins and can be selectively depolymerized from complex mixtures of plastic waste back to pure monomer at moderate temperatures using a separate depolymerization catalyst. The use of distinct polymerization and depolymerization catalysts allows for both synthesis and depolymerization of polyacetals under mild conditions, affording a practical method towards the catalytic conversion of polyacetals back to value-retained monomers.

Speaker Background:

Brooks Abel is an Assistant Professor in the Department of Chemistry at the University of California, Berkeley. He received a B.S. in Polymer Science and a Ph.D. in Polymer Science and Engineering (NSF Graduate Fellowship) from the University of Southern Mississippi. His Ph.D. work under the advisement of Prof. Charles McCormick focused on synthesizing stimuli-responsive water-soluble polymers using controlled radical polymerizations. Following his graduate studies, he worked as a postdoctoral researcher with Prof. Geoffrey Coates at Cornell University (2017-2021) where he developed bifunctional Lewis acid catalysts for the alternating ring-opening copolymerization of epoxides and cyclic anhydrides to synthesize well-defined polyesters. While at Cornell, he also developed a new living cationic ring-opening polymerization of cyclic acetals, enabling the synthesis of high molecular weight polyacetals with polyolefin-like tensile properties that can be near-quantitatively chemically recycled back to monomer. His independent research interests lie in the areas of polymer chemistry, stereoselective polymerizations, catalysis, and polymer recycling.
