South Africa Sweden student platform
The launch of the ‘Hot Topic’ debate series was one of the UFS SASUF student structure’s first points of business.

The University of the Free State (UFS) Office for International Affairs recently launched its first-ever UFS South Africa Sweden University Forum (SASUF) student structure during a hybrid event on the Bloemfontein Campus. 

As one of the 40 SASUF collaborating universities, the UFS has been encouraged to establish internal student structures that advocate for students' involvement and participation in activities promoting the enhancement of the Strategic Development Goals (SDGs), specifically quality education. Simba Matema, Assistant Researcher in the Office for International Affairs, was elected as the network’s representative for the UFS as well as the National SASUF coordinator.

Established in 2018, SASUF aims to strengthen ties between Sweden and South Africa in research, education, and innovation. 

Hearing student voices

Chevon Slambee, responsible for Virtual Engagement and select strategic projects in the Office for International Affairs, believes that this established student network provides an opportunity for students to make their voices heard and to impact policy imperatives related to the student community.  

“This intervention gives students a chance to engage on important matters that affect them in the student community. The student perspective is important and can contribute to positive change at the university,” she stated.

One of the first initiatives of the UFS SASUF student structure was the launch of the ‘Hot Topic’ debate series. 

The inaugural debate focused on the question: ‘Does our UFS culture allow for the preservation of indigenous knowledge?’ and permitted students to express their perspectives on this matter. It aimed to explore the extent to which the current institutional culture, along with Vision 130, either allows or inhibits the preservation and integration of African indigenous knowledge. 

Each debating team consisted of one student, one staff member, and one member from the UFS Debate Society. They deliberated on the following questions: ‘In a research-led institution, is there room for indigenous knowledge integration and preservation in an evolutional institutional climate?’ and ‘Does the current UFS institutional culture allow for the preservation of indigenous African knowledge?’

Slambee commented: “The debate provided students with a chance to not only encourage critical thinking on this topic, but also to think more strategically, enhancing articulation around this matter without taking things personally when someone disagrees. We aim to not stir up controversy, but to foster meaningful discussion and thoughtful involvement. We want the debate space to be a space where diverse views are respected and appreciated.”

Vision 130 promotes the notion of epidemic diversity. “Through the ‘Hot Topic’ debate series, we want to create a culture of care, as well as a vibrant space for and acceptance of constructive and critical engagement,” she added. 

“I was proud of the students; hearing their thoughts and contributions about the preservation of indigenous knowledge was pleasantly surprising,” said Slambee. 

“This is not a stand-alone event of the Office for International Affairs, but a collaboration with faculties and students,” said Slambee, who – with the next topic – would like to include other faculties besides the Faculty of Law in the process. 

Topics students can look forward to include discussions on the lack of funding opportunities for students in South Africa, and the importance of building sustainable relationships with surrounding communities. According to Slambee, the next debate will be hosted in the first semester of 2024.

Students’ involvement in important processes

“Besides being a great success, this event also illustrated the importance of harnessing the student voice in processes such as policy implementation and strategic decision-making – functions that essentially impact their academic and social lives,” said Matema.

With research as one of its focuses, SASUF would also like to feature research contributions from students. Slambee remarked, “I’m excited to see some of the student thoughts and perspectives that could inform new research and contribute to the overall quality of education and the student experience at universities.

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.
