Watch the livestream (live on 13 July 2023)

The University of the Free State is pleased to announce the upcoming UFS Thought-Leader panel discussion titled “A Culture of Acceptance – South Africa’s Greatest Threat?” as part of the 2023 Thought-Leader Series. A public South African higher-education institution, The University of the Free State (UFS) recognises its responsibility to contribute to the public discourse. In collaboration with the Free State Literature Festival, this event will bring together esteemed thought leaders to shed light on the social, political, economic, and business landscape of South Africa and its implications for our future. The panel discussion will be facilitated by Prof Francis Petersen, Vice-Chancellor and Principal of the UFS.

Panel discussion presented on 13 July 2023

The general state of decay we are currently experiencing in our various structures of governance on nearly all levels is preventing the economic growth that our country so desperately needs to move forward. Our current national financial status is clearly the result of not only poor government performance, but also a totally deficient policy environment. Part of the threats currently facing our country is civil society’s attitude of accepting rampant corruption, crime, and economic degradation as if it is something inevitable and unavoidable. The question is: has our current situation created a society that has simply accepted its fate? Or has it created a society that has become more innovative and creative, actively navigating current challenges, and finding new solutions to societal issues independent of government? These are some of the aspects we look forward to discussing with the esteemed panel.

Date:	Thursday 13 July 2023
Time:	10:00-12:00
Venue:	Albert Wessels Auditorium, Bloemfontein Campus
RSVP:	https://events.ufs.ac.za/e/ThoughtLeaderPanel by 10 July 2023

Refreshments will be served.

For further information, contact Alicia Pienaar at pienaaran1@ufs.ac.za.

Some of the topics discussed by leading experts in 2022 included, among others, Crime in South Africa – who is to blame; Are our glasses half full or half empty; What needs to be done to power up South Africa?; and A look into the future of South Africa. This year’s webinar series commenced in April, when we discussed Threats to South Africa’s stability and security challenges.

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

2016-05-09

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.
