Safety and security are human rights that constitute social justice. At the centre of the agenda at the University of the Free State’s (UFS) Social Justice Week held on the Bloemfontein Campus from 17-22 April 2019 were discussions about off-campus safety. Stakeholders agreed on an upgrade to security measures in order to ensure the success and wellbeing of the student population.

A call to students

Prof John Mubangizi, Dean of the Faculty of Law, in his capacity as representative of the UFS Rector and Vice-Chancellor, Prof Francis Petersen, expressed his view on institutions of higher learning no longer functioning as ivory towers. “For any initiative to succeed, collaboration is necessary between key roleplayers,” he said.

He aptly pointed out that: “We cannot underscore the importance of safety and security, not only for the university but also for the communities around us. What the university does benefits the community and vice versa. I pledge the university’s commitment to play a leading part to ensure that the collaboration works,” said Prof Mubangizi.

Beefing up security: Who is involved?

In view of the collaborative effort Prof Mubangizi alluded to, the engagement was twofold. First was the roundtable discussion facilitated by Protection Services which then escalated into a public dialogue where students had the opportunity to interact with external delegates.

The South African Police Services, Community Police Forum, Private Security, Mangaung Metropolitan Municipality, Provincial Commissioner, and Deputy Minister of Police were well represented in this critical conversation. Internally, members of Protection Services, Housing and Residence Affairs, Student Affairs, Institute for Social Justice and Reconciliation, Student Representative Council, and the Department of Criminology heard the plight of off-campus safety faced by students.

Changes in the horizon

The discussions culminated with recommendations which will see the future of student safety take a different direction. According to Skhululekile Luwaca, former SRC president, these include “the municipality’s commitment to immediately address issues such as street lights and enforcing by-laws, ensuring an integrated accreditation system, and drafting a policy for off-campus accommodation, running more crime awareness campaigns, and giving police patrols more visibility.”

In addition to resolving to set up a student safety forum with all the stakeholders, the Mangaung Metropolitan Municipality has invited the UFS to join Reclaim the City – a safety forum where practical solutions to crime are devised and implemented on a weekly basis.

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.
