The inaugural ‘Sanlam and Santam Economist of the Year’ competition gala, held on 18 October 2024 at the University of the Free State (UFS) Bloemfontein Campus, has been hailed as a significant opportunity for growth. Hosted by the Department of Economics and Finance in the Faculty of Economic and Management Sciences (EMS), in collaboration with Sanlam and Santam, the event celebrated the exceptional talents of young economists.

The gala brought together representatives from Sanlam and Santam, faculty members, the top 10 competition finalists, and the department’s leading academic performers from each year group. Jaco Geldenhuys, Senior Business Manager at Sanlam, commended the participants for their dedication, noting: ’Today, we not only recognise your academic excellence but also the potential, positive impact you will have in the world.’’

Prof Johan Coetzee, Chairperson of the Department of Economics and Finance, echoed this sentiment, emphasising that the competition aims to equip graduates to become global citizens who can solve problems, think critically, and communicate effectively in a constantly changing world.

What transpired during the event

The top 10 finalists presented their analysis in a 6-minute presentation before a panel of economists from the department, demonstrating their understanding of the macroeconomic environment, the methods they used to predict key macroeconomic indicators, and the lessons they gained from the process. After these presentations, the top three finalists were chosen and were required to respond to questions from the panel, determining the overall winner.

The top three included Tricia Khoza, who secured third place, Mokai Malope, who earned second place; and Reatile Seekoei, who was named the 2024 ‘Sanlam and Santam Economist of the Year.

All three finalists expressed their gratitude for the opportunity. Seekoei shared: “Competitions like this are invaluable because they prepare us for the working world. We have gained several graduate attributes we were introduced to at the start of our academic journey.’’

In addition to recognising the top three finalists, the department also awarded certificates to its top academic achievers, ranging from first-year undergraduate students to master's candidates.

Paving the way for the future

For many of the participants, the competition provided an invaluable glimpse into the professional world, offering them a chance to apply their classroom learning to real-world economic challenges. Geldenhuys encouraged the young economists to use their knowledge to challenge inequality, promote fairness, and drive innovation and sustainable growth.

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.
