As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the webinar as part of the Free State Literature Festival’s online initiative, VrySpraak-digitaal.

The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa. Some of the topics for 2021 include, among others, reimagining universities for student success; corruption; local elections, the state of business – particularly in the Free State.

In 2020, the webinar series saw the successful participation of leading experts engaging on COVID-19 and the crisis facing the country socially, economically, and politically. This year, in lieu of the Free State Arts Festival, the UFS will present the webinar virtually over a period of five months.

Fourth webinar presented on 24 August 2021
What South Africa will look like after the recent unrest in KwaZulu-Natal and Gauteng, is yet unknown. As the country is attempting to normalise while tallying the human, political, and economic cost of the riots – what we know for sure is that the events of the past few weeks have dispelled the impression of South Africa as exceptional, with a triumphant future. Moreover, the inconsistent response from government during and after the unrest laid bare the divisions within the ruling party. As South Africans are reeling from the aftermath of the looting, a lacklustre response from leaders with unreliable, conflicting messages has brought little comfort to those most in need.

What happens now? What will it take for South Africans to advance a cohesive vision to provide a sustainable future for the next generation?

Date: Tuesday, 24 August 2021
Topic: Is South Africa falling apart – where to from here?
Time: 12:30-14:00

Nikiwe holds an MA in Journalism and Media Studies from the University of the Witwatersrand, and an MSc degree in African Studies from the University of Oxford. She serves as trustee on the board of the Nelson Mandela Foundation, is a member of the Deloitte Global Advisory Council and an independent non-executive director of Deloitte Africa. Despite leaving journalism, Nikiwe remains a keen observer of society.
Ms Qaanitah Hunter

Qaanitah Hunter is an award-winning political journalist and author. She is the political editor of News24 and author of Balance of Power: Ramaphosa and the future of South Africa. Qaanitah has won a number of awards for her work, including the Nat Nakasa award for brave and courageous journalism in 2019. She is currently a master’s student at the University of the Witwatersrand.  She has reported fearlessly on state capture, the Zuma years, and the political transition thereafter. Her constant probing and investigations have played a pivotal role in holding truth to power. Her writing on South African politics and investigations has featured prominently on many national media platforms, often setting the agenda in the country. Qaanitah is well-versed in issues of governance and her well-rounded and balanced political reporting has contributed to her astute analysis of news and current affairs. She has fought strongly against censorship and intimidation among journalists and has been a strong advocator for the freedom of the press. Qaanitah believes that the prospect of any democracy to persevere is pinned on how free the media is and its ability to hold those in power accountable.
Prof Anthony Turton

Prof Anthony Turton is an Affiliated Professor in the Centre for Environmental Management at the University of the Free State (UFS). He specialises in strategic planning, transboundary water resource management, policy and institutional issues, conflict resolution (mitigation), political risk assessment for large infrastructural projects, and research programme design. He is also the Director of Nanodyn Systems Pty Ltd. Prof Turton’s focus is on resources, more specifically the need to overcome water and energy constraints to our future economic growth and prosperity, both as a country and the entire SADC region. As an environmentally aware person, he believes that we are reaching the limits to our current developmental approaches and will be forced to make changes in the near future, whether we like it or not. By understanding and anticipating this, Prof Turton assists organisations in staying ahead of the game by isolating fundamental drivers at work and by identifying emerging opportunities.

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.
