Opinion article by Prof Johan Coetzee (MCBI, CMBE), Chairperson: Department of Economics and Finance, University of the Free State.

The Minister of Finance has not had it easy in 2025 and the budget speech not read yesterday pays testament to this. Postponing the speech to 12 March is unprecedented, and is due to the Government of National Unity (GNU) not reaching consensus on a way forward to tabling a budget. It seems as if the fallout was based largely on a proposed 2% increase to VAT that was rejected by two parties. I personally would not have supported this proposal either as the tax burden shifts disproportionally to the poor.

My initial response of the postponement was frustration and disappointment. But I soon realised that it is the outcome of a new government dispensation made up of many voices, and many dissenting at that, becoming more important. In principle, this is good for the nation, but unfortunate for us expecting the budget to be read on the day. It also does not necessarily send a good message to the markets, with the rand weakening by more than 1% within an hour of the announcement. There could also be knock-on effects that a later tabling will have on service delivery and operations of government. After some reflection, however, I have concluded that on balance, the decision to postpone is not as problematic as many have made it out to be over the past 24 hours. Clearly there are many balls to juggle by Minister Enoch Godongwana and many added complexities that have both national and international dimensions.

Lead-up to the budget

Internationally the strong nationalist policy drive by US President Donald Trump has already shown that the ‘make America great again’ mantra is alive and well as reflected in the intentional actions taken against South Africa since his second term started in January. We will see how this plays out over the coming months, but my view is that South Africa as a nation needs to be more deliberate in its policy agenda. We are at an inflection point where we must reflect on who we are as a nation and where we want to be down the line. We cannot afford to rely on handouts from other nations. There is more opportunity to this situation than threat, but we need intentional leadership to exploit it.

My big concern in the lead-up to the budget speech was that the minister would not take a firm stand on fighting the culture of non-compliance within state entities which has invariably led to unsustainable levels of irregular expenditure. For the 2023/24 financial year, the Auditor-General of South Africa reported that irregular expenditure totalled almost R50 billion, up from just over R27 billion the previous year. To put this into perspective, irregular expenditure equals approximately 2.2% of total government spending for the 2023/24 fiscal year. This might not seem significant stated as a percentage, but it has basically doubled since the previous year, and every preceding year before that too. Moreover, irregular expenditure equates to approximately 20% of the 2023/24 social grants budget and just about equals the 2024 National Student Financial Aid Scheme allocation. This is clearly a management failure and nothing seems to have been done about it over the years. As a result, the problem is escalating at an alarming rate. It is quite astounding that accountability management is not more explicit as it is clearly a very unpopular political message to send. But at what cost?

South African economy is not growing

To make matters worse, the South African economy is not growing both enough and fast enough. The most recent real GDP growth figure showed a decrease of 0.3% in the third quarter from the second quarter of 2024. Since 1994, the period with the highest annual rate of growth was a three-year period from 2005 to 2007 where growth exceeded 5% for each respective year. This period preceded the global financial crisis and since then, growth has struggled to reach 3% annually, doing so on only two occasions barring the 4.7% in 2021 which was not a true reflection of reality given the low base of the preceding year amid the COVID-19 pandemic. This is a major concern for the Minister, because with economic growth comes increased tax revenues, which in turn capacitates better budget management. Very simply, the more people spend; the more businesses sell; the larger the profit outcomes; the larger the tax revenue collections. If the economy grows, the fiscus collects more tax revenues without explicitly increasing tax rates. This built-in cyclical dynamic is simply not happening and creates a serious constraint on the ability of the Minister to manage deficits going forward.

Further to this of course is that as deficits are run, all things remaining constant, public debt increases. The public-debt-to-GDP ratio for 2023/24 already exceeds 72% which is higher than the generally accepted benchmark of 60% and almost 2.6 times what it was in 2008 (27.8%). This has resulted in the average interest on public debt approximating R1.1 billion a day, equating to about 22% of total tax revenues, or almost 20% of total government spending respectively. To put it differently, for every R1 government spends, 20 cents is first channelled to pay the interest on the debt before any spending occurs on roads, education, infrastructure, social grants and the like. These are deeply concerning figures in an economy with already high levels of unemployment and inequality.

Might be beginning of something better

There is a leadership void that cannot be ignored anymore. It needs to be intentional and deliberate. The GNU provides the platform to exploit ‘the best that South Africa has to offer’ as it promotes a broad-based and more inclusive political structure and played itself out yesterday. I welcome this in principle, but my concern is that political in-fighting will prevail and perverse politicking will trump working together in the best interests of the South African people. Although the postponement could be interpreted negatively in terms of the GNU not being able to find common ground, I think it is rather a sign of more rigorous engagement and the enablement of a collaborative environment amongst parties in the decision-making structures of the state. Remember this day as it might be the beginning of something better than what we are used to.

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.
