UFS Green Campus Initiative Team

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.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
