Empowering the youth to shape tomorrow’s democracy.

As South Africa prepares for its national elections scheduled for 29 May 2024, the University of the Free State (UFS) emphasises the importance of youth engagement in the democratic process. These sentiments were echoed during the Human Rights Day event recently hosted by the Free State Centre for Human Rights.

Exercising the right to vote

Aligned with the university’s Vision 130 strategy, which prioritises societal development, the UFS aims to educate and engage its community members on the significance of voting as a catalyst for positive change. Through initiatives like the Human Rights Day event, the university fosters awareness and advocacy for democratic principles, empowering individuals to exercise their right to vote and contribute to shaping the nation’s future.

Advocating for democratic principles

Dr Annelie De Man, Coordinator of the Advocacy Division at the Free State Centre for Human Rights, highlighted the relevance of the Human Rights Day event in light of the elections. “We celebrated Human Rights Day by raising awareness amongst our students regarding the rights that they possess including the right to vote, especially with the South African national elections approaching. We also wanted to convey the message that even though we as a country are experiencing many challenges, we still have our constitutionally guaranteed and hard fought-for rights that guarantee that our human dignity and right to equality must be respected.”

The event held on the Bloemfontein Campus served as a platform to raise awareness among students about their rights and the role of the Free State Centre for Human Rights. Limeque Redgard, a student assistant at the centre, described the event as an opportunity to educate students on human rights within the institution and to introduce them to available support mechanisms in case of rights violations.

Student-led advocacy

Badumetsie Tsieane, Executive Committee Chairperson of the Human Rights Ambassadors, noted the importance of making human rights discussions engaging for students and highlighted the role of ambassadors in promoting awareness and advocacy.

The event showcased the enthusiasm and commitment of students towards understanding and championing human rights, and also underscored the impact of initiatives like the Free State Centre for Human Rights in empowering the youth to participate actively in shaping a just and equitable society.

A call to action

As the nation gears up for the elections, UFS encourages students to exercise their democratic right to vote. Recognising the challenges faced by the country, the university reaffirms its commitment to promoting civic engagement and upholding the principles of human rights and democracy. With the support of initiatives like the Human Rights Day event, the UFS aims to equip students with the knowledge and awareness necessary to become informed and responsible citizens. By fostering a culture of engagement and advocacy, the university strives to contribute to the development of a vibrant and inclusive democracy in South Africa.

As the countdown to the elections continues, the UFS remains dedicated to empowering the youth to play an active role in shaping the future of the nation through their participation in the democratic process.

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.
