Charné Ferreira
Kovsies is proud of Charné Ferreira one of just 12 candidates to be placed on the Honours Roll of the South African Institute of Chartered Accountants.

The South African Institute of Chartered Accountants (SAICA) recently announced the candidates who wrote and successfully met the requirements of the Assessment of Professional Competence (APC) examination. One of 2 024 names released was that of Charné Ferreira, a University of the Free State (UFS) alumna.

Ferreira was among 3 560 candidates who attempted the APC in November 2019. This gruelling part of her journey to becoming a Chartered Accountant (CA) was a culmination of many years of intensive education and training.

Now a Senior Associate at PricewaterhouseCoopers, Ferreira reflects on how her career started with the decision to take Accounting as a subject in high school. In her second- and third-year as a Kovsie student, Ferreira challenged herself to become a tutor. This gave her the opportunity to secure a position as an Academic Trainee at the UFS School of Accountancy.

Recognising outstanding performance
Not only did Ferreira pass the most demanding Chartered Accounting test in South Africa, but she excelled and earned a place on the institute’s prestigious APC Honours Roll. SAICA honours only 12 exceptional candidates for their aptitude and skill. 

Excellence to match market demands
According to Freeman Nomvalo, CEO of SAICA: “In many ways this is the toughest exam because it requires aspirant Chartered Accountants (CASA) to apply their technical academic knowledge from multiple disciplines to a single but complex real-life business case study. To pass, candidates must demonstrate high levels of the skills employers have told us they want in the next generation of CAs (SA).

“Succeeding at this final test of professional competence requires advanced levels of critical thinking, the ability to work with technology, and the capacity to assimilate new information under pressure over a five-day period which culminates in an eight-hour assessment. It’s gruelling but it’s exactly the kind of challenge successful candidates will soon face as qualified CAs (SA),” added Nomvalo.

A word to the wise
Looking back at the building blocks that led her to this point, Ferreira shared invaluable advice for future candidates. “Ask for help, speak up if you do not know, speak up if you are drowning in stress. Your career is not a sprint, it is okay if you fail, as long as you get up again and the most important thing is, make time to rest, do not be so hard on yourself,” she said.

In congratulating Ferreira and the other UFS alumni who passed the 2019 Assessment of Professional Competence, Prof Frans Prinsloo, Director: School of Accountancy, also paid tribute to the excellent work of the UFS academics in the School who play a vital role in developing the knowledge, skills and values of the next generation of accounting professionals. “These results attest to the quality of the Chartered Accountancy education offered by the UFS,” he said.

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.
