ERN-Environmental Engaments: talks

Freddy Kleitz "What can we do to improve the recovery and recycling of critical materials?"



About the talk:

Critical materials (CMs) are elements considered to be highly important for the modern economy, but which face widespread supply risk. Some examples of metals that have received the CM designation include the rare earth elements (e.g., dysprosium, neodymium, and terbium), indium, cobalt, and lithium. Many of these CMs are especially important for the development and expanded use of green energy technologies, however, only very high purity fractions are appropriate for those applications. Rare earth elements (REEs) and their compounds are essential for rapidly developing modern technologies. Yet, achieving efficient REE separation and purification in an economically and environmentally effective way remains a challenge. There has been a recent surge in research dedicated to mitigating the supply risks associated with different CMs, especially REEs. Common avenues of investigation include designing new and improved techniques for extracting REEs from primary resources, assessing the viability of previously unexploited REE feedstocks, developing methods to recycle REEs from waste products, and replacing CMs with functionally similar metals that do not face the same supply constraints. Within the area of REE recovery from primary and recycled feedstocks, there are a variety of new methods which demonstrate promising results for selective REE extraction and purification from resources as diverse as geothermal fluids and mining waste. This talk will focus on these separation issues and the solutions which could be offered by solid-phase extraction (SPE), one broad category of these experimental extraction technologies.


About the speaker:

Freddy Kleitz is a University-Professor in the Faculty of Chemistry at the University of Vienna, Austria. Since 2016, he is the director of the Department of Inorganic Chemistry-Functional Materials. He received his Ph.D. degree in Chemistry in 2002 from the Max-Planck-Institut für Kohlenforschung and the Ruhr University Bochum, Germany. In 2002-2003, he was a postdoctoral researcher in KAIST in South Korea. In 2005, he joined the Department of Chemistry of Université Laval, Canada, where he was awarded the Canada Research Chair on Functional Nanostructured Materials. He was then promoted Full Professor in 2014. His research focuses on the design of functional nanoporous inorganic and organic-inorganic hybrid materials and their applications as selective sorbents, heterogeneous catalysts, and biomedical materials. He has published over 170 refereed research articles, reviews and book chapters and has also been a guest Professor at the University of Queensland, Australia, and at the China University of Petroleum in Qingdao, China.
