Food parcels

Between 40 and 50 students from the University of the Free State (UFS) in Bloemfontein receive daily food parcels during the lockdown, thanks to the cooperation between the Food Environment Office at the UFS, Tiger Brands, and the Total Garage in Brandwag.

Annelize Visagie from the Division of Student Affairs (DSA), who is heading the Food Environment Office at the UFS, says just before the national lockdown started in March, they signed a Memorandum of Understanding (MOU) with Tiger Brands to sponsor 500 food parcels to students who do not have bursaries. This is part of the UFS strategic goal of improving student success and wellbeing. UFS staff is working hard to implement initiatives and obtain sponsorships – such as this one with Tiger Brands – as well as food donations to ensure that students do not go hungry.

“Then the lockdown happened. However, the project continued, with Tiger Brands still sponsoring food parcels. Students email me and I respond to those emails. We are also looking at including students from the South Campus in the project.”

“I deliver the food parcels to the Total Garage across from the campus, where students collect it. We give between 40 and 50 parcels every day and have helped 650 students thus far. These parcels cost Tiger Brands R80 000 a month. We also provide students with vegetables from vegetable tunnels on campus,” says Visagie.

Visagie says the cooperation between the outside companies, the UFS, and even staff and students who volunteer, is heart-warming to see especially during this time of crisis. So is the gratitude from the students. They are also in discussions with the humanitarian organisation Gift of the Givers to provide 200 food parcels to needy students from next month.

“We have a supply chain going on in the storeroom at the Thakaneng Bridge. It is great to see how staff members and students jumped in to help us pack the parcels. We have permits and more students want to help, but they can’t get onto campus at this time. We would not be able to do this without the help of Tiger Brands and the Total Garage.”  

The DSA Food Environment Office is also collaborating with senior management on the UFS Qwaqwa and South campuses to distribute food parcels on these two campuses.

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.
