Prof Sethulego Matebesi is a Senior Lecturer and Academic Head of the Department of Sociology at the University of the Free State.

This year’s Freedom Day marks an important milestone in the history of South Africa. It will be 27 years since the first non-racial elections were held in the country, a figure that equals the number of years Nelson Mandela spent in prison.

If equating Mandela with the freedom we enjoy today is not already disingenuous enough, we sunk even lower by assuming that we are close to achieving the civil liberties he embodied. You do not have to go further than read the daily media headlines to understand the extent of the onslaught on the pillars of democracy. That this onslaught comes from political leaders is one of the main reasons why most South Africans are disillusioned with politics, democracy and social issues.

Anarchy wreaking havoc in weak societies

Sociology taught me about the relevance of institutions to a social structure: they control human conduct by setting up predefined behaviour patterns. For example, throughout history anarchy has wreaked havoc in settings where organisations are weak, fragmented, and the citizenry is inactive. Similarly, while peace, unity, and the preservation and the restoration of human dignity are the hallmarks of Freedom Day celebrations, we have become a nation increasingly influenced by symbolic politics and the politics of offence.

It would be hard to find a better example of a significant threat to the pillars of democracy than the widespread onslaught on the judiciary. At the heart of the broader political, legal, and moral issues confronting SA today is how the right of all to equal respect and equal protection under the law has been compromised. Casting doubt about the independence of the judiciary conceals the motivations that most endanger the principles of freedom and equality.

My stance is not aimed at muting the expression of unpopular opinions – a basic tenet of democracy. However, we need to be mindful of events that have and will become powerfully symbolic in altering the nation’s social fabric.

Freedom under attack by populist politics

Any societal change requires some form of flexibility. No doubt, the first decade of democracy was accompanied by hope and the euphoria of the Rainbow Nation. This period demonstrated how different racial groups could live together in harmony, play together, and attend the same school without being required to forsake values they hold dear. This period was punctured by notions of active citizenship and the promotion of democratic cooperation that is based on the acceptance of universal human rights and the rule of law and values of diversity.

While millions of people elsewhere in the world have been forced to flee hunger, war, terrorism, and emboldened autocrats in their countries of birth, the euphoric wave of the Mandela years has, unwittingly and dramatically, worn off during the past decade in South Africa. This turn of events is linked to populist politics that seriously compromise democratic institutions in the country.

In my opinion, there are no heroes in situations like these.

In a country characterised by rampant corruption, violent crime, gender-based violence, human trafficking, racial intolerance, and teenage drug abuse, are politicians the only ones to be blamed for the threats to democracy?

Conquering immorality and safeguarding our freedom

Despite all the challenges we face as a country, we remain a remarkably resilient nation, as is widely acknowledged. This resilience is echoed by how we have navigated our way around a highly divisive and intolerant society to embrace and celebrate our rich and vibrant cultural heritage.

Nevertheless, we have become complacent. We have been vocal against any narrative aimed at restricting our legal, religious, human, civil, economic and political rights. Yet, partly due to our collective inaction, we have failed to use the means to provide a compelling counter-narrative of resistance to the manipulation of state institutions and broader immorality permeating society. This inaction affects the lives and livelihoods of millions of those who do not have the organisational capacity and means to advocate for the causes that affect them.

Let us use this year’s historic Freedom Day celebrations to demonstrate our firm resolve to protect the critical pillars of democracy from further exploitation. This kind of collective responsibility is what South Africa has always been about. Only when our government at all levels, the private sector, and concerned citizens across the country begin a critical partnership and commitment to maintain our democratic institutions and processes that our past losses as a nation become gains and defeats become triumphs.

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.
