At a meeting held on 26 November 2021, the Council of the University of the Free State (UFS) approved the awarding of the UFS Council Medal for outstanding service to Nico Janse van Rensburg, Senior Director: University Estates.

Building our campuses

Janse van Rensburg completed a BSc Quantity Surveying degree at the UFS in 1989 before joining the institution’s then Department of Physical Planning in 2004, after an impressive career as quantity surveyor. In 2012, he was appointed Senior Director: University Estates, continuously adding value to the infrastructure of our three campuses – totalling more than 500 000 m² – as well as experimental farms and off-campus entities of more than 1 000 ha.

He has a persistent green approach that not only reduces the UFS’ carbon footprint, but also saves the institution millions of rands in energy savings and maintenance. Indigenous and waterwise gardens greet staff, students, and visitors to all our campuses, while being housed in well-maintained buildings. All newly built facilities on our campuses are based on green building principles, while an overall optimal building management system ensures efficient energy management.

Mentorship and skills transfer

University Estates, through its procurement management and the leadership of Janse van Rensburg, is also one of the main drivers behind the UFS’ BBBEE scorecard. He initiated a mentoring and skills transfer strategy by means of joint project appointments, enabling previously disadvantaged firms to eventually be appointed independently for similar projects.

To ensure, among others, aesthetically pleasing buildings that offer value for money, Janse van Rensburg and his team have developed a series of technical manuals that outline material specifications and expectations. Since 2012, he has been instrumental in more than 1 000 projects at the UFS.

The university recognises and commends Janse van Rensburg’s indispensable contribution to creating inclusive and quality spaces on our campuses, where staff, students, and visitors can experience our culture of care. His motto is clearly visible in all the projects he completes: Get things done – within time, budget, quality standards, expectations, and user satisfaction.

“It is an immense privilege to be leading the University Estates team, and I am humbled to be the recipient of this prestigious medal. University Estates is all about teamwork, and an award such as this can only be possible through the commitment, dedication, and support of a very capable team, as well as colleagues throughout the UFS. I would also like to thank our very capable leaders, such as Prof Prakash Naidoo, Vice-Rector: Operations, for his support and guidance. I have learnt a lot on this journey and a lot remains to be learnt. All of this could only be achieved with help that goes beyond one’s own strengths and abilities,” said Janse van Rensburg.”

Get things done – within time, budget, quality standards, expectations, and user satisfaction.

The Council Medal will be presented to Janse van Rensburg during a graduation ceremony in 2022.

Carbon dioxide makes for more aromatic decaffeinated coffee

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way.

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night.

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants.

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
