Hosting the South African Circular Agriculture Initiative (SACAI) – an initiative of the Department of Science, Technology and Innovation’s (DSTI) – will help position the Green Futures Hub at the University of the Free State (UFS) as a leader in circularity in agriculture.

The UFS Green Futures Hub was selected to host the SACAI from 1 January 2025-31 March 2026. The funding received will be used to conduct workshops with stakeholders to develop a strategy to strengthen South Africa’s science, technology, and innovation for a circular economy in the agriculture sector.

The SACAI, under the leadership of Prof Wayne Truter, Research Professor at the UFS Centre for Mineral Biogeochemistry, and Executive Management of the UFS Green Futures Hub, aims to advance the principles of the circular economy and modernise agriculture in line with the South African government's aspirations. These goals are outlined in the Science, Technology, and Innovation (STI) Decadal Plan (2022-2032) and the Circular Economy STI Strategy.

 

Elevating the UFS’ visibility

The UFS Green Future Hub is a virtual platform in the Faculty of Natural and Agricultural Sciences (NAS), to facilitate integration and leverage capabilities to facilitate third stream funding and industry collaboration. It provides an interface and support structure for researchers to engage with funders and partners through the Hub.

Prof Truter says it is a great honour and privilege to have been awarded this initiative. “The funding that comes with SACAI will elevate our visibility in agriculture in the country and will help position Green Futures Hub as a leader in circularity in agriculture. A key objective of SACAI is to leverage science, technology, and innovation to enhance the value of the national system of innovation (NSI) within the agriculture sector. 

“The initiative will align with the priorities set out in the Circular Economy STI Strategy (2024-2034), focusing on resource efficiency, regenerative agriculture, sustainable agro-processing, and biorefinery development in South Africa. Through collaborations with other public research institutions, the hub will drive STI implementation in these critical areas,” says Prof Truter.

 

Objectives of SACAI 

The objective of SACAI is to give effect to the (i) circular economy, and (ii) modernising agriculture, aspirations of the South African government. The SACAI aims to advance the principles of the circular economy and modernise agriculture in line with the South African government’s aspirations. 

Simultaneously, Prof Truter explains, the objectives of the SACAI align with the vision of the UFS Green Futures Hub to be a global leader in advancing the understanding and application of sustainable practices for life with land and water, in developing contexts. By leveraging the latest advancements in research, technology, and innovation, the hub aims to create a thriving future where communities harmonise with natural and agricultural environments, ensuring the well-being of current and future generations, which has a particular focus on modernising agriculture and capacity development. 

Through STI, the SACAI will support the South African agriculture sector to adopt, scale and accelerate circular practices and technology. The SACAI will act through a hub-and-spoke model, to build and strengthen a national system of innovation, and associated capability, and will establish and strengthen strategic regional and international STI partnerships, to directly support industry and other sector stakeholders, serving as a facilitator of relevant research and related outputs.

 

UFS’ Vision 130 

“A South African Circular Agricultural Initiative perfectly aligns with our research-led, student-centred, and regionally engaged university by driving innovation and knowledge production in sustainable agriculture. This initiative will enable the university to contribute to development and social justice by advancing circular farming practices that reduce waste, optimise resources, and promote environmental sustainability, particularly in rural areas. 

“This fosters greater food security and resilience, benefiting marginalised communities, and addressing social inequalities within the agricultural sector. By involving our students, this initiative will directly support the student-centred approach, offering hands-on learning experiences that equip graduates with cutting-edge skills in circular economy principles,” says Prof Truter. 

The university’s Vision 130 focus on diversity, inclusion, and equity is reflected in the initiative’s emphasis on sharing knowledge and resources equitably, ensuring maximum societal impact and advancing a more just and sustainable agricultural system across South Africa.

Prof Vasu Reddy, UFS Deputy Vice-Chancellor: Research and Internationalisation, says: “This accolade speaks volumes of the calibre of our scholars and the recognition of our expertise in the agricultural domain. The UFS is exceptionally proud of Prof Truter’s drive, initiatives, vision and foresight. Under his leadership, we will augment and inflect even further our standing and position in the circular economy of agriculture. Reddy added: “We will not simply be the heartland but the growing soul and substance of what agriculture might become through research, implementation and impact. We are watching this space with deep curiosity.”

Researcher takes home gold at international Famelab competition

Recently, University of the Free State (UFS) Centre for Environmental Management master’s student, Tshiamo Legoale, was announced the FameLab International champion at the Cheltenham Science Festival in the United Kingdom. She is probing methods to use wheat as a gold hyper-accumulator – or, as she puts it, “grow gold from wheat”. The young researcher made South Africa proud by winning both the audience’s and the judges’ vote.

Coming back home a hero
“Winning was a surprise to me, because all 31 contestants had wonderful research. They all had really good presentations. I’m very grateful for all the support that I received from home. Social media showed me a lot of love and support. When I felt unconfident, they gave me ‘likes’ and that boosted my confidence a bit,” said Legoale about her win.

As South Africa celebrates Youth Month in June, Tshiamo represents hope for thousands of young South Africans to overcome difficult circumstances and follow careers in science.

The human impact is crucial, because Legoale’s win is not only scientific. It is also social and political. As a young female scientist in South Africa, she represented one of three African countries making it to the finals of FameLab, which has grown to one of the largest science communication competitions internationally.

With this in mind, Legoale says it may, in the end, be necessary to balance the needs of communities with the desire to increase yield. “Are we looking to make a fortune or are we looking to put food on the table?” she asks. “These are all things we consider when we conduct such research.”

World-class research from Africa
In South Africa, an estimated 17.7 million tons of gold is wasted. “All this gold was mined out previously, but tiny amounts remain in the dumps,” Legoale explains.

Her research focuses on the uses of wheat as a gold hyper-accumulator, which essentially means wheat plants are used to harvest gold from mine dumps. Simply put, the wheat is planted in the dumps, where enzymes found in the roots react with the gold and the plant absorbs it. The gold is then absorbed by every part of the plant, except the seeds, which means the next harvest can be used for food if need be.

“South Africa's world-champion young scientist, Tshiamo, represents all that is good about this country – brilliant, bright, and set for a fine future. I'm so proud that British Council SA, together with our partners SAASTA and Jive Media Africa, can help her along the way. Huge congratulations to her from all of us – it is a big win for Africa on the world stage,” said Colm McGivern, British Council South Africa Country Director.

The research represents a win on multiple levels. First, there are the obvious potential socio-economic benefits: food production, job creation, and phytomining is more economical than other contemporary mining methods.

Then there is safety. It is a more environmentally friendly practice than methods like heap leaching, carbon-in-leach or carbon-in-pulp. It is also safer for miners themselves, who will not be exposed to dangerous chemicals like mercury, which has been responsible for a great deal of toxicity in mine dumps. And it is safer for those living in the surrounds.
