Waste2Value: A Paradigm Shift in Sustainable Resource Recovery. A talk by Prof. Herman Potgieter on Thursday 4th May at 18:00 in E0.32, John Dalton building. (Refreshments available from 17:30).
Mining is notorious for being viewed as a dirty, polluting and generally unsafe industry. However, the face of modern mining has changed significantly, and the new frontier in mining is “urban mining”. It is therefore necessary to make a complete mind shift in how we view both mining activities as well as wastes.
While the matrix of the products recovered from recycled waste has changed, many of the traditional hydrometallurgical and pyrometallurgical processes to recover and re-use it have not changed much. These processes remain mostly costly, highly polluting and consume vast amounts of energy. It is therefore necessary that new processing routes be developed to extract raw materials from such sources.
This discussion will concentrate on and present several such new processing options, their advantages and potential for future use, while illustrating it with some practical examples.
Herman started his career at the University of the Free State and obtained his BSc (majoring in Mathematics, Chemistry and Physics), BSc (Hons) Chemistry and MSc in Chemistry. Through part time studies he graduated with a PhD in Metallurgy and Materials Engineering at the University of the Witwatersrand in 1996 and with a Doctor in Technologiae in Chemistry at Technikon Pretoria in 2002.
His working career started at the Atomic Energy Co-operation, after which he lectured at the University of Pretoria, continued to work at Mintek (Council for Mineral Technology) as Principal Scientist, Pretoria Portland Cement as Senior Chemist, Technikon Pretoria as Professor and Head of the Department of Chemical and Metallurgical Engineering, and the University of Witwatersrand as Professor and Head of School of Chemical and Metallurgical Engineering.
Currently he holds a dual position as full professor at Manchester Metropolitan University in the School of Research, Enterprise and Innovation as Head of Analytical Development and in the School for Chemical & Metallurgical Engineering, University of the Witwatersrand, Johannesburg, SA. His research spans a myriad of areas, including stainless steels, especially with additions of Platinum Group Metals )(PGMs), polymers, water treatment, cement and lime, analytical method development and waste material abatement. He specializes in the corrosion behaviour of stainless steels, extraction of metals from ore and waste materials and the use of fly ash as a novel material.
A total of 8 Ph.D, 35 master’s degree students and 92 undergraduate students have successfully completed their research projects under his supervision. Currently 3 more Ph.D students in the UK and another 2 in South Africa, as well as 4 more M.Sc students in SA are being supervised. Nine postdoctoral researchers have worked with and were supervised by Herman during his academic career.
He has numerous contributions at national and international conferences and seminars and published more than 200 peer-reviewed articles in peer-reviewed and ISI accredited journals. He has been cited more than 2300 times and has a h-factor of 25. He has published 4 chapters in books, holds 2 patents and has 45 conference proceeding papers. He is associate editor for the scientific journal Corrosion Engineering Science and Technology, and is a member of the editorial boards of the Journal of SAIMM and African Corrosion Journal.
Herman holds the status of CEng from the Institute for Materials, Minerals and Mining, as well as CChem from the Royal Society of Chemistry. He is a fellow of the following learned organisations: Institute of Materials, Minerals and Mining (IOM3), Royal Society of Chemistry (UK), Society of Mining Professors, South African Institute for Mining and Metallurgy, the Water Institute of Southern Africa and Associate Fellow of the South African Institute for Chemical Engineers/IChemE organisation. He is also member of the South African Corrosion Institute, South African Academy for Science and Art, Society for Chemical Industry (UK) and the Institute of Corrosion (UK).
Herman holds visiting positions at the following institutions:
Tshwane University of Technology, Pretoria, South Africa as professor extraordinaire in metallurgical engineering and the University of Antwerp as visiting lecturer in Applied Chemistry.
Refreshments will be available from 17:30 in MMU’s John Dalton building, with the talk beginning in Lecture Theatre E0.32 at 18:00. This will last around one hour and will include time for audience questions. The event will finish with a drinks reception and further discussion.
Attendance to this event is free of charge, however we do ask that you book tickets in advance at http://waste2value.eventbrite.co.uk/
