Prof Johan Coetzee, Head of the Department of Economics and Finance at the University of the Free State (UFS), has been named the recipient of the Fiat Lux Award – the highest honour bestowed by St Andrew’s School in Bloemfontein. 

The award, presented at the annual St Andrews Speech Day awards ceremony on Thursday 16 October, recognises Old Andreans (alumni of the school) who have made exceptional contributions to society through professional excellence and personal integrity.

 

A journey of values, excellence, and lifelong connection

Previous recipients of the Fiat Lux Award include notable figures such as former Nedcor CEO Richard Laubscher, palaeoanthropologist, Apartheid activist, and three-time Nobel Prize nominee Prof Phillip Tobias, former President of the American Chamber of Commerce in South Africa Roger Crawford, and Carte Blanche Executive Producer George Mazarakis.

Prof Coetzee, who matriculated from St Andrew’s in 1995, describes the recognition as deeply humbling. “It is difficult to put into words what this means to me. As an Old Boy of St Andrew’s, it puts the seal of approval on the career path I chose – one that started in the corridors of that school 38 years ago,” he says.

He recalls that his school years shaped both his outlook and his work ethic. “The school taught me the importance of teamwork and resilience. It made me realise early on that life is not all rosy, and that one must maintain a balanced perspective – that is what sets St Andrew’s apart.”

For Prof Coetzee, this honour is not only a personal milestone but also a reflection of the close ties between the UFS and local schools of excellence. “It is extremely important for the UFS to maintain strong links with schools like St Andrew’s, which acts as a feeder for future students and athletes. It’s a win-win situation for both institutions,” he says.

He hopes that his recognition will inspire current learners at St Andrew’s to pursue their goals with perseverance. “I hope that this award awakens the drive in the current crop of pupils at Saints to realise that anything is possible – that your background or the setbacks you face do not define you. Also, and perhaps more importantly, that hard work and persistence does pay off.”

Prof Coetzee’s achievement reflects the UFS’ value of Excellence, exemplifying the university’s commitment to nurturing leaders who embody integrity, dedication, and a lifelong pursuit of learning.

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.
