UFS Green Campus Initiative Team
The UFS Green Campus Initiative team after being announced winners for the fourth consecutive year.

The University of the Free State (UFS) is celebrating an outstanding achievement at the 12th Annual Green Campuses Conference (GCC) 2025, where its dynamic Green Campus Initiative (GCI) team from the Qwaqwa Campus clinched the coveted Best Exhibition Award. This marks an unprecedented fourth consecutive year that the UFS has secured this prestigious accolade, highlighting its unwavering commitment to sustainability and innovation within the higher education landscape.

Hosted by Nelson Mandela University in Gqeberha, Eastern Cape, the conference was presented by the Association of College and University Housing Officers - International (ACUHO-I) under the profoundly relevant theme, Ubuntu and Environment: African Indigenous Knowledge in Sustainability. Endorsed by the Department of Higher Education and Training, the GCC serves as a pivotal platform for institutions of higher learning across South Africa to exchange vital knowledge, share best practices, and explore groundbreaking innovations in environmental sustainability and climate change mitigation.

The UFS GCI team's exhibition captivated judges and attendees alike with its exceptional creativity, innovative spirit, and profound dedication to envisioning a greener future. "The creativity, innovation, and commitment to sustainability shone through every detail of the display," remarked residential head Itumeleng Lebusho, "a true reflection of what it means to envision a greener future".

The five students who represented the institution were Amukelani Ngobeni, Minenhle Mnguni, Sinenhlanhla Mathabela, Charmaine Nokubonga Nkosi, and Thandolwethu Nyathikazi.

A cornerstone of the student-driven conference, the GCC featured three main categories: project presentations, a runway showcase, and the highly anticipated exhibition. UFS students excelled across the board, demonstrating their ingenuity in tackling real-world campus challenges with sustainable solutions.

A particularly notable project was the student-designed mobile trolley. Addressing a common predicament faced by students transporting groceries from the main gate to their residences due to campus restrictions on taxis for security reasons, the team engineered an innovative solution. This solar-powered mobile trolley, equipped with batteries and a motor, began as a prototype in 2024 and has since evolved into a testament to student-led problem-solving. While the current iteration requires a Code 8 driver's licence to operate, its potential to revolutionise campus mobility is clear.

The conference's annual theme encourages participants to devise sustainable solutions to problems faced on campus, a challenge that the UFS GCI team has embraced with remarkable success.

The UFS' consistent triumph at the GCC is a testament to the dedication and sacrifice of its students, whose forward-thinking ideas continue to push the boundaries of what is possible in campus greening. "The students worked in a way that we never imagined," expressed Desiree Motsele, Residence Head within Housing and Residence Affairs. "The ideas that they come up with are truly inspiring."

By actively participating in this significant event, the UFS is not only strengthening its commitment to creating a green campus but also fostering a healthy learning and living environment. This continued dedication prioritises sustainability, advances energy efficiency, champions resource conservation, and promotes environmental stewardship, solidifying the UFS' position as a leader in sustainable practices within South African higher education.

The Director: Student Affairs, Zoleka Dotwana, said she would like to congratulate the students on yet another gold they won at the GCI 2025. “The effort, the hard work, the commitment you have shown, has once again raised our UFS flag high. I hope the experience and the graduate attributes you have learnt in preparing your project will go a long way in providing you with great opportunities when you leave our shores. It has been an awesome journey over the four years, one that we hold dear and that will remain in the history books of our campus. Thank you for flying our flag high - Only a Kovsie knows the feeling!' said an ecstatic Dotwana.

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.
