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.”

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
