Attaining his master’s degree cum laude, completing a PhD degree, and publishing in top academic journals, University of the Free State (UFS) academic, Dr Victor Gwande, has been an outstanding researcher throughout his career.

Adding to his list of notable achievements, the postdoctoral research fellow in the International Studies Group has just been awarded a fellowship at Princeton University, one of the top universities in the world. The US institution was recently ranked sixth in the Times Higher Education World University Rankings 2020.

As a fellow of the Institute for Advanced Study at Princeton, Dr Gwande will spend two weeks on the Ivy League university’s New Jersey campus in 2020. This will be followed by a weeklong session at one of two collaborating institutions in South Africa and the US, with continuous communication facilitated among selected scholars throughout a two-year period. 

Flying high the flag of the African academy
Dr Gwande believes the fellowship will expose him to new intellectual traditions and perspectives. “It will help me create international academic networks across continents, as I seek to put my name out there as an internationally recognised scholar.”

With his research interests in economic and business history of Southern Africa, Dr Gwande says he wishes to become “a great scholar of African economic history, flying high the flag of the African academy, as well as training and producing young scholars for the academy”.

Working with some of the world’s top minds at Princeton University, there will be much to focus on.

“I will be researching, writing, and presenting my research project in which I use the case study of the Anglo American Corporation to look at the histories of capitalism and to understand how monopoly capitalism shaped economic trajectories of Zimbabwe and the broader Southern African region.”

Longer-term plans include completing his monograph stemming from his PhD thesis.

There are many people to thank for his journey from the UFS to Princeton, and the scholar draws attention to some of those who have influenced him. 

“God and my family. But in my career, quite a number of people and institutions have really moulded me; the International Studies Group under Prof Ian Phimister has given me an environment to flourish in my young career.

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.
