SIM² Welcome
SIM² KU Leuven (Sustainable Inorganic Materials Management) is an interdisciplinary research cluster at KU Leuven, which addresses the European and global demand for more cleantech innovation and research on resource recovery and recycling.
Extraction of rare earths from bauxite residue
In the context of the EU Horizon 2020 MSCA-ETN REDMUD project, KU Leuven researchers have published a new method to extract rare earths (REEs) from bauxite residue (red mud) by dry digestion followed by water leaching.
New PhD on REE recovery from bauxite residue
On July 2nd, 2018, Dženita Avdibegović (SIM² KU Leuven) obtained her PhD degree in Chemistry. She successfully defended her PhD thesis entitled ‘Recovery of rare earths from bauxite residue leachates by functionalised sorbents‘.
Liubov Lukina is a PhD student at the Department of Materials Engineering at KU Leuven. She is working on the magnetic separation of rare-earth ions. She has a MSc degree from Lappeenranta University of Technology (Finland).

REDMUD
Applications are invited for the one PhD position funded by the Marie-Sklodowska-Curie “REDMUD – European Training Network for Zero-Waste Valorisation of Bauxite Residue” within the H2020 Programme of the European Commission

Rationale

The sustainable and secure supply of raw materials to the EU is a vital, strategic, long-term issue for Europe. This Grand Societal Challenge is directly addressed by SIM² KU Leuven whose mission is to develop, organise and implement problem-driven, science-deep research and future-oriented education, contributing to the environmentally friendly production and recycling of metals, minerals and engineered materials within a circular-economy context.

SIM² KU Leuven: scope of resources that are addressed

Scope of materials

SIM² KU Leuven targets both primary ores, extractive waste, industrial process residues and urban solid waste. Key focus areas are (1) metal extraction from increasingly complex, polymetallic, low-grade ores; (2) metal recovery from stocks of extractive waste (incl. tailings) and landfilled industrial process residues (e.g. sludges, dusts, slags…); (3) metal recovery from flows of industrial process residues from primary and secondary metal production; (4) direct (preconsumer) recycling of metal scrap and swarf generated during the production of metal-based (intermediate) products; (5) (postconsumer) recycling and/or urban mining of, respectively, flows and stocks of complex, multi-material, metal-containing products (e.g. End-of-Life Hybrid Electric Vehicles) as well as construction and demolition waste); and finally (6) landfill mining of historic urban solid waste. SIM² KU Leuven targets a near-zero-waste vision, which implies that any kind of residual mineral matrices are upcycled into added-value materials such as inorganic polymer binders and derived engineered products. Hazardous components are concentrated into specific phases that can be safely stored.

SIM² KU Leuven timeline

SIM² KU Leuven has existed as an interdisciplinary research line within KU Leuven MRC since 2011. The establishment of SIM² KU Leuven was based on previous successes, which date back as far as 2003 when the HiTemp Centre was initiated at the Department of Materials Engineering. This Centre, which still exists today, was set up as an Academic Competence and Service Centre, structurally funded by several world-leading, Flemish-based metallurgical companies, including Umicore and Aperam. Subsequently, the Centre led to interdisciplinary collaborations with other research groups at KU Leuven, both within the Department of Materials and beyond, in the field of geology, building materials, chemical metallurgy, recycling, environmental and techno-economic assessment, policy research, process psychology etc. Here below the reader can view the timeline of the various collaborations, platforms programmes and projects developed through SIM² KU Leuven are summarised, showing that the SIM² KU Leuven cluster grew “organically”.
