Pieter-Jan Boeykens is currently a PhD student at Ghent University in the Sustainable Materials Science Research group. His PhD is in cooperation with Umicore and is funded by a personal scholarship from the Flemish government. His current project focusses on the electrical conductivity of non-ferrous recycling slags containing lead oxide and iron oxide. The aim of the project is to obtain both experimental data as well as to improve existing conductivity models.

Dr. Kai Tang earned his Ph.D. in Metallurgy and Material Engineering from Shanghai University in 1997. He has since been a Senior Research Scientist at SINTEF Industry in Norway, focusing on process modeling, silicon refining, and SiC advanced materials. As an Associate Professor in China and abroad, he supervised graduate students and contributed to education. Dr. Tang's research has earned awards and led to over 100 publications. His project leadership secured substantial research funding and fostered industry-academia collaborations, making him a respected figure in materials science and metallurgy.

Jenny Isaksson defended her Ph.D. thesis in December 2023 and now has a position as an associated lecturer in Process Metallurgy at Luleå University of Technology.

Dr. Mengyi Zhu received his B.Sc. degree in metallurgical engineering from the University of Science and Technology Beijing (USTB), China, in 2013, and his M.Sc. degree in the same field from RWTH Aachen University, Germany, in 2017. He received his Ph.D. degree in metallurgical engineering in 2021 from the Norwegian University of Science and Technology (NTNU), Norway. His Ph.D. research concentrated on silicon purification through acid leaching and slag refining techniques. Currently, his research interests span the fields of slag engineering, computational simulations of slags, and the development of sustainable metallurgical processes.
