Prof Motlalepula Matsabisa, a specialist in indigenous knowledge systems from the Department of Pharmacology at the University of the Free State (UFS), is part of a delegation with Prof Blade Nzimande, minister of Science, Technology, and Innovation (DSTI), to the Second Ministerial Belt and Road Science and Technology conference (BRT) in China. 

The conference is being held in Chengdu from 11-12 June 2025 and will gather representatives from state-level agencies, scientific academies, and innovation enterprises from countries involved in the Belt and Road Initiative, including members of the Association of Southeast Asian Nations (ASEAN) and the Shanghai Cooperation Organisation. The theme of the conference is “Together for Innovation, Development for All – Jointly Building a Scientific and Technological Innovation Community for the Belt and Road”. 

Prof Matsabisa, Research Director of the African Medicines Innovations and Technologies Development at the UFS, is the only person from a South African university to be invited by Prof Nzimande as part of this ministerial trip. Other members of the delegation include members from the minister’s department, CEOs and board members of agencies that report to the DSTI – namely Technology Innovation Agency (TIA), the National Science and Technology Forum (NSTF), Council for Scientific and Industrial Research (CSIR), National Advisory Council on Innovation, Human Sciences Research Council of South Africa, South African Council for Natural Scientific Professions, National Science and Technology Forum (NSTF), National Advisory Council on Innovation (NACI), South African National Space Agency and the National Research Foundation (NRF). 

As a guest professor at the Beijing University of Chinese Medicine (BUCM) in Beijing, Prof Matsabisa accompanied the delegation on a visit to the university where he has a longstanding relationship. The UFS has the only active university collaboration within the China-South African Science and Technology bilateral agreement.

 

Supporting around aspects of traditional medicine 

According to a statement on the South African government website, Prof Nzimande expressed the department’s intention to strengthen collaboration with the Beijing University and the Aerospace Research Institute of the Chinese Academy of Sciences, in the areas of indigenous knowledge systems and space science, respectively. The minister visited both the BUCM and the Aerospace Information Research Institute of the Chinese Academy of Sciences this week. 

“It is an honour to be part of the minister’s delegation given that I am the only person from a university amongst the agencies. The UFS is indeed very honoured to have been the only one identified to be in this ministerial trip. I am honoured to make connections with the decision-makers such as the chairperson of the board of TIA and the CEO of NSTF and all the other CEOs. It’s indeed an honour to share our work with people from NACI and the minister’s office at DSTI. This really could not have been a better opportune moment for me,” says Prof Matsabisa. 

According to him, he is there to support Prof Nzimande around aspects of traditional medicine as well as with his meeting with the Chinese Minister of Science and Technology during the signing of a letter of intent on traditional medicines including in the BRT conference where the minister will give a talk that will cover traditional medicines. Prof Matsabisa says he is looking forward to strengthening the relationships between the UFS and BUCM and China as well as sharing with the minister the joint projects and joint students from both institutions, hoping for continued support and funding.

“This trip has opened new opportunities. TIA has invited me and the UFS to be part of their new project on neurodegenerative diseases with Cuba. It was wonderful to hear that both the CEO and the chairperson of the board had already been briefed about me to be part of the project.

“It is also great to be present at the signing of the letter of intent on traditional medicine as it is important to know where the policies are heading.”

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.
