Inaugural presentation_Yiannis Pontikes_2017
- 1. Fe-Ca-silicate slags: when purpose-driven research challenges perception of what is feasible Leuven, March, 2017 Yiannis Pontikes
- 2. In the next ~30min Few slides about my motivation & more slides about the SREMat group: why and what we do, now and in the near future. We will start from a high altitude and land smoothly!
- 8. My motivation These slides speak about me I am 2nd generation refugee (see: “population exchange” of 1923) That grew up next to an American base, with Greek-Canadian citizenships, having family in 3 US states, and my sister in London Now an immigrant (or “expat”?) Emotionally bonded with Belgium, but Europe (the world) also And a father (did you meet Sebastian Theodore?) That believes global warming is real, we don’t live in a sustainable way, and finds demagogues threatening!
- 9. My motivation And I feel responsible And just watching, is just too difficult The real damage is done by those millions who want to 'survive.' The honest men who just want to be left in peace…Sophie Scholl
- 10. But I am not alone
- 11. So, what do I want to do? Use science and expand our understanding, so that we develop processes with smaller environmental footprint Create tools for individuals to have more safe, healthy and comfortable lives Educate others to become more aware of their impact and options …
- 14. Paris Agreement

- 18. Transform local supply of residues towards new materials Circular economy through zero waste processing …and the vision
- 19. And circular economy/zero waste is…? https://www.ricoh.com/environment/management/concept.html > 20 years ago!
- 20. OK! OK? Are we getting there? …we have 15 years to make it happen…but we started good! Figure: P.T. Jones
- 21. Fe2O3-Al2O3-CaO-SiO2 FeO-Al2O3-CaO-SiO2 SiO2-”FeO”-CaO-Al2O3 CaO-SiO2-MgO CaO-”FeO”-MgO-SiO2 …comes down to the 4 most abundant metallic elements FeOx-CaO-Al2O3-SiO2 But isn’t every slag different?
- 22. And the more you look… Two slags from completely different processes have MO/SiO2 close to 2, the 3rd major oxide being at approx. 7wt%, everything else < 5wt% Aperam and Metallo slags are not that far! Iacobescu et al. J. Clean. Prod., 112(1), 872–881, 2016 Iacobescu et al. Front. Chem. Sci. Eng. DOI 10.1007/s11705-017-1622-6 (accepted)

- 24. Al2O3 Al2O3Al2O3 Cu, Zn, FeNi Al2O3 Cu, Pb In the high temperature process, metal is also recovered! Carbon steel, stainless steel But what if we go towards one “unified”?

- 26. SREMat: group for a cause
- 27. 27 The group aspires to conceive and develop innovative processes in order to transform secondary resources towards engineered materials, while considering the sustainability of the envisaged process and the fate of (critical) metals. The vision of our team is to create sustainable material loops. SREMat: group for a cause
- 28. SREMat: Secondary Resources for Engineered Materials, is one of two research units in the HiTemp research group at MTM Members: 3.5 post-docs, 9+3+1+2 PhD, typically 5 MSc students per year and 2 visiting The person is important, strong bonding. Very international team BE, GE, GR, RO, SK, FIN, SRB, COL, ECU, IN, ET (BRA, IT, CHN) SREMat: group for a cause

Outreach/educate These are the conferences that are collaborating with the journal Presents news on “sustainability + metal” from >10 portals These are the conferences that are collaborating with the journal As they appear at Springer website As they appear at Zenodo https://zenodo.org/com munities/sustainmetall/
- 50. Tools The “tool” will allow people to make their own houses, without going through intermediates players in the value chain And yes, Flanders, is quite OK, but we don’t make this tool for Flanders only, we make it for the world (and users like UN…)
- 53. Before we close… And if we succeed… Yes, we almost close the loop!
- 54. And we close… Thank you for being here! I am greatly indebted to every member of SREMat (MSc and PhD candidates, but postdocs in particular for making things happen), colleagues at MTM and KU Leuven, SIM2 especially, and to the people I collaborated at industries as well as institutions that we have received funding and trust from. Big thank you to SO...
