On the morning of 23 February 2022, some of the entrance gates to the Bloemfontein Campus were blocked by groups of protesting students. The gates were cleared by members of Protection Services and traffic could continue to enter and exit the campus.

Sporadic disruption of classes occurred during the course of the day, with several students being arrested by the South African Police Service (SAPS) for disruption of classes, which is contravention of the interdict.

The disruptive behaviour stems from students’ unhappiness with the response to the memorandum handed to the university management by the Bloemfontein Campus Central Student Representative Council (CSRC) on 21 February 2022. Also on 21 February, a memorandum was handed to the management of the Qwaqwa Campus by the campus’ CSRC. The Qwaqwa Campus was temporarily closed yesterday, following violent protest action this week; the date for the reopening of the campus will be communicated in due course. 

Today’s disruptive behaviour demonstrated by the group of students on the Bloemfontein Campus is condemned and will not be tolerated.

During this week and on numerous occasions before that, the university management has been in extensive engagements with the CSRCs on both campuses; concessions were made where possible, as was demanded in the two memoranda. However, the responses given, and the concessions made by the university were not accepted by the student leadership of the Bloemfontein Campus CSCR in particular, with more demands being made.


Concessions from the beginning of 2022:

To ensure that students register successfully for the 2022 academic year, the UFS has granted a number of financial concessions to students since the beginning of the year. The financial support given was specifically intended to fast-track the registration process of students with outstanding debt, and those awaiting confirmation of funding from the National Student Financial Aid Scheme (NSFAS). 

These concessions included:

  • Allowing students who have previously registered for foundation programmes and those who have continued with mainstream programmes to register without the prerequisite of a first payment. The provision was granted to students who applied with the N+ rule and whose respective foundation programmes are included in the Department of Higher Education and Training-funded list.
  • Permitting students with outstanding debt of up to R25 000 and who await NSFAS funding to register provisionally.
  • The university also allowed conditional registration for first-time entering students, giving those who have applied for NSFAS funding until 28 February 2022 to finalise their registration. First-time entering students, both residential and non-residential, could register conditionally, provided that they pay an amount of R500.

Demands in the two memoranda received from the CSRCs on the Bloemfontein and Qwaqwa Campuses included matters such as private accommodation; emergency accommodation; catch-up plans for students who have not yet registered; a registration threshold increase to R30 000; NSFAS allowances; and the extension of registration for international students without study permits. The Bloemfontein Campus CSRC did not accept the university’s responses to the memorandum.

The university management will continue engaging with the SRC.

Safety measures in place:

The situation on the Bloemfontein Campus is closely monitored. Protection Services is on high alert and continues to work closely with the SAPS to ensure stability on the campus.

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.
