A team of exceptional students from the University of the Free State (UFS) has claimed victory in the prestigious SDG Challenge South Africa, a global competition that unites students and organisations to address the United Nations Sustainable Development Goals (UNSDGs). This remarkable achievement not only underscores the skill and dedication of UFS students but also reinforces their commitment to forging a more sustainable and equitable world.

The group of students from different disciplines within the Faculty of Natural and Agricultural Sciences (NAS), came up with an interdisciplinary and forward-thinking approach which contributed significantly to their victory. The team members, including Pieter Bruwer, Dr Anathi Makamane, Dr Brandon van Rooyen (all from Sustainable Food Systems and Development), Daniel Naudé (Department of Agriculture Economics), as well as Dr Yolandi Schoeman (a postdoctoral fellow in the Centre for Environmental Management (CEM) from the Faculty of Natural and Agricultural Sciences, each brought their unique expertise to the challenge.

Prof Jan Willem Swanepoel, Associate Professor in the Department of Sustainable Food Systems and Development within the Faculty of Natural and Agricultural Sciences, provided invaluable mentorship to the team. The students were also supported by Robyn Mellett from OMI Solutions.

Dr Schoeman says the SDG Challenge, designed to confront global challenges, connects students and organisations from across the globe, fostering collaboration towards achieving the UNSDGs, which encompass critical issues such as climate change and the reduction of global inequalities. Teams from South African universities, including the University of Cape Town, Stellenbosch University, and the University of KwaZulu-Natal, partnered with leading companies to address specific challenges tied to their corporate missions.

Develop a waste management strategy

Team UFS joined forces with Ivanhoe Mines, a prominent mining company operating in the Democratic Republic of Congo to develop a waste management strategy for the Kamoa-Kakula Copper Complex. This endeavour was laden with complexities due to the limited waste management options available in the area. The challenge was not just about managing multiple waste streams from the mining complex, but also about addressing socioeconomic and biodiversity challenges stemming from the burgeoning population in the region, which led to a range of environmental concerns.

“In response, the UFS team innovatively conceived ÉcoFlotille, a solution that not only tackled essential waste management issues but also promoted biodiversity net gain. The plan extended its reach to support local agribusinesses and small and micro-enterprises through the repurposing and reuse of waste materials, while presenting a unique biofinancing opportunity. The EcoFlotille solution represents a distinctive aspect of their triumphant journey.

“ÉcoFlotille not only aligns with the SDGs but also plays a crucial role in realising the vision of the Kunming-Montreal Global Biodiversity Framework, which emphasises the conservation and sustainable use of biodiversity. Additionally, it aligns with the goals of Agenda 2063 for Africa, striving to advance the continent’s development objectives and create a prosperous and harmonious future for the region,” says Dr Schoeman. 

The scalability of ÉcoFlotille across Africa holds great promise. Its innovative waste management approach and biofinancing potential could serve as a model for addressing similar challenges in diverse regions of the continent. This opens up opportunities for wider adoption and positive impacts throughout Africa.

Creating a more sustainable and equitable world

The SDG Challenge South Africa is an integral part of Soapbox’s global mission to mobilise university students and organisations in working collaboratively toward the UNSDG. These goals aim to address the world’s most pressing challenges, requiring collective efforts to achieve sustainable economic growth, environmental sustainability, and social inclusion by 2030.

The UFS’s remarkable success in the SDG Challenge not only highlights the university’s dedication to fostering global citizenship and sustainability but also underscores the remarkable potential of its students in driving positive change in Africa and the world.

According to Dr Schoeman, the UFS team’s victory in the SDG Challenge stands as a testament to their unwavering commitment to creating a more sustainable and equitable world. Their innovative solution, ÉcoFlotille, serves as a beacon of hope, illustrating how the vigour and ingenuity of the younger generation can propel us closer to realising the UNSDG by 2030, effectively ticking all 17 SDG boxes.

Solving a real-world problem

Prof Swanepoel says the SDG Challenge is a global competition that unites students and organisations to address the UNSDGs. These goals encompass some of the most pressing challenges facing our world today, such as climate change, poverty, and inequality.

According to him, by participating in the SDG Challenge, the UFS students had the opportunity to apply their knowledge and skills to solve a real-world problem experienced by one of the biggest mining houses in the world. They gained valuable experience in collaborating with the private sector.

“I am immensely proud of the students' achievement in the prestigious Soapbox SDG Challenge South Africa. Their interdisciplinary approach and forward-thinking mindset are a testament to the calibre of education and mentorship they receive at the UFS,” Prof Swanepoel says. 

“Furthermore, I am confident that the skills and experience gained through the SDG Challenge will help the students to make a positive impact on the world. They are the next generation of leaders who will be responsible for addressing the complex social and environmental challenges Africa face. I also believe that coming out as victors in this competition would open more doors for them and the university in the private sector.”

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.
