SANRAL Chief Executive Officer Skhumbuzo Macozoma and UFS Rector and Vice-Chancellor Prof Francis Petersen cutting a cake to mark 10 years of collaboration between the two institutions.

The Science-for-the-Future (S4F) programme is fundamental to generating the required pipeline for technologically skilled entrepreneurs and workers by focusing on Mathematics and Science support to learners, teachers, and parents.

This is according to the South African National Roads Agency Limited (SANRAL) Chief Executive Officer, Skhumbuzo Macozoma, who delivered a keynote address at the Annual Science for the Future Summit held at the University of the Free State (UFS) on 20 September.

The S4F is a partnership between the UFS and SANRAL, with the fundamental purpose to train Maths and Science teachers and to support learners and parents. The programme has now been extended to six other universities, namely Nelson Mandela University and Walter Sisulu University in the Eastern Cape; the University of Limpopo, University of KwaZulu-Natal, and the two recently established universities, the University of Mpumalanga and the Sol Plaatje University in the Northern Cape.

Dr Cobus van Breda, the Programme Director for the UFS S4S, said they developed the Family Math and Key Concepts in Science programmes to address issues that prevent learners from excelling in these critical subjects. It seeks to improve the content knowledge of teachers and provide them with more skills-teaching resources.

Macozoma said: “I am proud and deeply honoured to stand before you today in the strength of a successful 10-year partnership with the University of the Free State which we are celebrating here today, together with the hosting of the Annual Science for the Future Summit.”  More than 300 teachers attended the summit.

Planning for the future

He indicated that SANRAL's long-term strategy, Horizon 2030, instructed the development of a new human-resources strategy for the organisation, which has identified three pillars that underpin SANRAL's human-capital development initiatives, namely people, skills, and performance.

“The strategic opportunities identified by SANRAL include capitalising on the opportunity presented by the digital revolution to create a new generation of technologically skilled entrepreneurs and workers; returning to good and ethical governance in both the public and private sectors; bringing back the prestige of serving the citizens of SA through state institutions: fashioning SANRAL as an employer of the future and delivering technical skills to address the glaring skills gap in engineering and other domains,” he said.

Macozoma stated that SANRAL has also decided to review and rationalise its support to institutions of higher learning in order to grow the footprint of its support programmes, increase the impact, and ensure equity.

Beyond this, he stated that SANRAL wanted to ensure that learners are equipped with fundamental competencies that are essential to complement academic teachings, including critical thinking, creativity, collaboration, communication, information literacy, media literacy, technology literacy, and flexibility.         

Facing 4IR head on

Macozoma said the most important characteristics of the Fourth Industrial Revolution that must be taken into consideration by those who aim to survive it, drive it, and benefit from it, is a smart customer – who is informed and dictates what services he/she wants and how they should be delivered; technology at the fingertips – which will enable rapid, real-time, borderless services to information, services, and technology as an enabler – bringing efficiency to logistics, mobility, medicine, education, industries, the economy, the military, global trade, and politics.  

Working closely with school and society

UFS Rector and Vice-Chancellor, Prof Francis Petersen, said the university has an important responsibility to generate knowledge that will impact society positively.

“We have a role to work closely with our schools and society so that we can understand each other’s needs,” he said.

“We need to strengthen collaboration with all our partners so that we can travel further and make an impact in our society,” said Prof Petersen.

One of the participating teachers in the S4F programme, Grace Molante, from a primary school in Zastron, said: “It is programmes such as these that instil hope in us as teachers. Some learners could find Maths and Science very difficult and challenging subjects, but this programme makes problem solving more enjoyable and practical.”

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.
