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.”

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
