Chemical Society Seminar:Troels Skrydstrup - From Plastic Disassembly to Carbon Capture with Waste Plastic

Abstract:
The vast amounts of end-of-use plastics and plastic-containing materials released into Nature has resulted in a major environmental crisis, strongly affecting ecosystems across the globe. There is an urgent need for the implementation of a circular economy of plastics and plastic-containing composites for reducing the consumption of resources, as well as limiting the introduction of waste into the environment. In this talk, I will summarize our synthetic efforts on the use of transition metal catalysis for the disassembly of thermoset plastics to base chemicals, including products prepared from polyurethanes and epoxy composites. Thereafter, I will present our recent work devoted to the selective chemical transformation of waste plastic to new materials with carbon capture properties.

Bio:
Troels Skrydstrup received a BSc degree in chemical engineering from Queen鈥檚 University, Kingston, Canada (1983) and his MSc and PhD degrees from the Technical University of Denmark (1985 and 1988). After several post-doctoral periods at l鈥橧nstitut de Chimie des Substances Naturelles, Gif-sur-Yvette, France (1988鈥�89, 1990鈥�92) and at the Carlsberg Laboratories (1989鈥�90), Troels Skrydstrup was employed as a Charg茅 de Recherche (CR1) in the CNRS both at l鈥橴niversit茅 d鈥橭rl茅ans and l鈥橴niversit茅 Paris XI (1992鈥�1997). In 1997, he became Associate Professor at the Department of Chemistry, Aarhus University, and was promoted full Professor of Organic Chemistry in 2002. Currently, he is center leader of the Carbon Dioxide Activation Center at Aarhus University, and the co-director of the Novo Nordisk Foundation CO2 Research Center.
Membership and awards: Troels Skrydstrup was elected as a fellow of the Royal Danish Academy of Sciences in 2008, as member of the Danish Academy of Natural Sciences in 2010, and the Danish Academy of Technical Sciences in 2015. He was knighted by the Danish Queen in 2012. In 2001, he received the Holm鈥檚 Research Prize. In 2018, he was awarded the Melvin Calvin Award 2018 for outstanding scientific contributions in the field of isotope science, and the same year the Science Award from the Faculty of Science and Technology, Aarhus University. In 2022, he received the Bjerrum, Br酶nsted, Lang award. Troels Skrydstrup has been visiting professor at l鈥橴niversit茅 de Versailles (2001), Osaka Prefecture University (2007), l鈥橴niversit茅 Paris Decartes (2008), Nanyang Technological University, Singapore (2013), l鈥橴niversit茅 de Bordeaux (2014) and Nanchang University (2018). 2
