2023 UFS Thought-Leader Webinar Series

The University of the Free State (UFS) is pleased to present a panel discussion titled, Student protest action, politics, and higher education, which is part of the 2023 Thought-Leader Webinar Series. Join Prof Adam Habib and Dr Max Price for a discussion about their respective experiences in leadership positions during the #RhodesMustFall and #FeesMustFall student protest movements, the lessons learnt during these tumultuous times, and how these events continue to influence the current landscape in the higher education sector in South Africa and further afield. The discussion will reflect on their recent books Rebels and Rage: Reflecting on #FeesMustFall, and Statues and Storms, and will be facilitated by Prof Francis Petersen, the Vice-Chancellor and Principal of the UFS.


Date:   Tuesday 21 November 2023

Time: 13:00-14:30

Prof Adam Habib

Prof Adam Habib is an academic, researcher, activist, administrator, and well-known public intellectual. A Professor of Political Science, Prof Habib has more than 30 years of academic, research, and administration expertise, spanning five universities and multiple local and international institutions.

Prior to his appointment as Director of SOAS, he was Vice-Chancellor and Principal of the University of the Witwatersrand (Wits) in Johannesburg, South Africa between 2013 and 2020. He has also served as Deputy Vice-Chancellor of Research at the University of Johannesburg, Executive Director of Democracy and Governance at the Human Sciences Research Council, and as Director of the Centre for Civil Society and Professor of Development at the University of KwaZulu-Natal. He is widely published, including his two well-received monographs, South Africa's Suspended Revolution: Hopes and Prospects and Rebels and Rage: Reflecting on #FeesMustFall.

Prof Habib’s academic contributions resulted in his election to the American Academy of Arts and Sciences, in addition to serving as a fellow of both the African Academy of Sciences and the Academy of Science of South Africa. He also serves on the Council of the United Nations University.

 

Dr Max Price

Dr Max Price was appointed Vice-Chancellor of the University of Cape Town in July 2008, completing his ten-year term in June 2018. During the first seven years of his term, UCT experienced growth and success in research and teaching, as well as global recognition. This continued during the last three years but was overshadowed by the Rhodes Must Fall and Fees Must Fall protests during 2015 to 2017. Dr Price led the university through these storms and back to safe harbour in 2018.

Dr Price studied Medicine at the University of the Witwatersrand (Wits), during which time he became deeply involved in student politics, becoming SRC president a year after the Soweto uprising. He subsequently did a PPE degree at Oxford as a Rhodes Scholar. Following clinical work in academic and rural hospitals in South Africa, he gained a master’s degree in Community Health at the London School of Hygiene and Tropical Medicine, and then worked as an academic in the areas of health policy and economics, rural health services, and health science education.

He was dean of the Faculty of Health Sciences at Wits for ten years. He now consults in public health, higher education, strategic leadership, and advises foundations on grant making. He is currently a scholar in residence at the Atlantic Institute. He is the author of Statues and Storms: Leading through change, published in 2023.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
