G20 - 2025
G20 delegates from member countries and other invited guests in attendance at the G20 Research and Innovation Working Group (RIWG) and G20 Initiative on Bioeconomy (GIB) meetings and other side events.

Against the backdrop of the upcoming G20 Summit to be hosted by South Africa in November 2025, the University of the Free State (UFS) – in partnership with the Department of Science, Technology and Innovation (DSTI) – held the G20 Research and Innovation Working Group (RIWG) and G20 Initiative on Bioeconomy (GIB) meetings on 23 and 24 February 2025.

In her opening address to G20 delegates from member countries, national and international knowledge partners, members of the Free State provincial government, and representatives of the DSTI, Prof Hester Klopper, Vice-Chancellor and Principal of the UFS, indicated, “It is an honour for the UFS to be among the few South African universities to host this essential Research and Innovation Working Group.” In addition, she highlighted that the deliberations and discussions set to take place during this important workshop can set in motion chains of events ultimately contributing to improved lives for everyone. These sentiments were also echoed by Prof Blade Nzimande, Minister of Science, Technology and Innovation, who underscored the importance and historic nature of the upcoming G20 Summit.

In his virtual address, Minister Nzimande explained that South Africa’s chosen theme for the G20 Summit – Solidarity, Equality and Sustainability – was inspired by the general complexity of our time, “in particular the transnational nature of these complexities, such as conflict, the displacement of people, poverty”, among other things. As such, he expressed that in this case, cooperation among nations is becoming increasingly essential.

As they concluded their addresses, Prof Nzimande and Prof Klopper, wished the delegates well in their deliberations. ‘’May your discussions be successful, and your goals be achieved. And may your time with us lead to a renewed experience of the value of innovation through connection, ‘’expressed Prof Klopper.

 

Contributing events

As part of the programme at these proceedings, several side events took place. These included panel discussions with indigenous knowledge holders such as Telle Hoeses, Chief Language Practitioner for Khoi and San Languages, along with experts of indigenous medicine. The conversation focused on indigenous knowledge systems (IKS) and some of the key concerns and progress that these knowledge holders have made in the space. In addition, these knowledge holders, many of whom are business owners who sell products made from indigenous medicines, also had the opportunity to exhibit their products. According to Dan du Toit, Deputy Director-General: International Cooperation and Resources at the DSTI, these panel discussions with young people, bioeconomy researchers, and indigenous knowledge holders were an opportunity to gain access to a diversity of voices, which would not normally find expression in formal meetings. “It is also an opportunity for our international guests to get insight into who we are as a country and what some of our concerns might be,” said Du Toit.

One of the highly anticipated side events on the programme was the joint G20 RIWG and GIB event titled ‘UNESCO Women and Girls in Science’, which took place on 25 February 2025. The event took the form of a round-table discussion, in an attempt to answer the question: Based on your experiences in various roles within higher education in South Africa, Africa, and globally, what are some key insights regarding the role of universities in closing the gender gap in STEM, specifically concerning professional development and creating supportive research environments where everyone, especially women, can thrive?

Prof Anthea Rhoda; Deputy Vice-Chancellor: Academic at the UFS, was one of the contributors in this session. In response to the question, Prof Rhoda highlighted, “Universities should also be spaces characterised by intellectual freedom and freedom of expression, where archaic ideas about male superiority and patriarchy can be openly confronted and contested, without fear of victimisation. She expressed that an active way in which the UFS has committed itself to a culture of diversity and inclusion is through Vision130.

As she was wrapping up her address, Prof Rhoda also highlighted, “To address areas of underrepresentation of women in senior academic and leadership positions within the university, a Working Group on Gender Parity in Academic Leadership was established, with the critical mandate to drive attitudinal shifts, advocate for changes where necessary, and highlight barriers to women’s advancement.”

 

The programme comes to an end

The last day of the programme was reserved for comments, reflections, and discussions on deliverables. As such, there were positive responses to the way the deliberations took place. In fact, Hoese, speaking in her capacity as an indigenous knowledge holder, said, “This was a good platform for us to make progress towards language recognition and officialisation.”

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.
