BUAN Delegates
Botswana University of Agriculture and Natural Resources (BUAN) delegates that recently visited the University of the Free State to solidify a collaboration.

During an inspiring journey, a delegation from the University of the Free State (UFS) recently visited the Botswana University of Agriculture and Natural Resources (BUAN) with an ambitious goal: to solidify a collaboration that was sparked during the visit of BUAN’s Vice-Chancellor to the UFS and subsequent discussions in Namibia. The atmosphere was one of shared purpose and excitement as the UFS representatives, led by the Dean of the Faculty of Natural and Agricultural Sciences, the Vice-Dean: Agriculture, and the Vice-Dean: Postgraduate and Research, embarked on this significant academic endeavour.

This visit was not just a formal gesture, it was a step towards tangible, mutual benefits for students and staff of both institutions. The discussions between the UFS and the BUAN leadership, which centred around possibilities for student and staff exchanges and shared access to specialised equipment, pointed to the potential of creating a dynamic bridge between South African and Botswana academia. This partnership envisions collaborative supervision of postgraduate students, creating opportunities for intellectual growth that transcends borders. The two universities also explored joint funding applications and research avenues, with particular interest in BUAN’s innovative Meat Institute and AgroVolts solar panel project. Seeing the BUAN’s progress in renewable energy left the UFS team particularly impressed, reflecting the possibilities for sustainable development and resource-sharing that a partnership could yield.

During the discussions, the UFS delegation had a pivotal meeting with the BUAN’s Acting Deputy Vice-Chancellor: Academic and Research, Prof Samodimo Ngwako, who had previously visited the UFS. His familiarity with the UFS’ resources and vision made him an invaluable advocate for bridging the two institutions, highlighting how their strengths could complement each other. Prof Ngwako’s insights helped BUAN staff visualise the meaningful exchange of expertise and resources that could benefit both student bodies and contribute to third-stream income generation.

With the way forward clear, both the UFS and BUAN teams agreed on ‘quick steps’ to launch the collaboration – the swift signing of a Memorandum of Understanding (MoU), followed by the first exchange of students and staff, and the launch of co-supervised research projects. While specific timelines and milestones are to be confirmed post-MoU, both teams are keen on joint funding applications, especially in areas relevant to agricultural and natural resources both within Africa and beyond. This partnership, once formalised, is expected to solidify both universities as leading research hubs in agriculture and natural resources, advancing each institution’s standing on the continent.

Reflecting on the visit, the UFS delegation felt a deep sense of optimism. The collaboration between the UFS and the BUAN aligns seamlessly with the UFS’ broader vision for strengthening ties with African universities, showcasing a forward-thinking approach to partnerships. As the journey towards meaningful collaboration progresses, the shared enthusiasm witnessed at the BUAN serves as a hopeful reminder that academia – when united by common goals – can drive impactful change for students, faculty, and communities on both sides of the border.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
