The Kovsie ACT programme encourages the evolution of UFS students to form internationally competitive graduates who embody sustainable energy knowledge and skills to contribute to the development of the global environment.

Be a part of the evolution and livestream this year’s University of the Free State (UFS) Kovsie ACT Eco-vehicle race on 15 May 2021.

What’s in it for you? Get exposed to an informative but exciting event that will assess the technology and logic behind sustainable energy sources and how this will influence the future global society.

According to Karen Scheepers, Head of the University of the Free State (UFS) Kovsie Act office, the quest for sustainable resources remains one of the top-five challenges facing the global population of today. This challenge – together with issues pertaining to food insecurity, water, waste and toxins, and the widening gap between rich and poor – poses new questions to the kind of graduates that universities produce, she added.  She further highlighted the importance of innovative critical thinking that responds to day-to-day issues experienced by society in a global context.

Therefore, the UFS has initiated an eco-vehicle project to help students develop the necessary graduate attributes to specifically address issues of sustainable resources. The aim of the eco-vehicle project is to implement, within the context of a higher education institution, a new innovative skills development solution to the challenge of sustainable resources, and to evaluate the efficacy and impact of this programme in a rigorous way. 

Through this programme, senior undergraduate students worked together in teams through a mediated learning programme to build scale-model electric vehicles and mini solar charging stations – powered by solar energy (or batteries charged through solar energy).  This experience will steer them towards finding solutions and creating awareness around 21st century issues, and adapting to the development of technology and globalisation, essentially producing an interdisciplinary experience for UFS students.

Kovsie ACT eco-vehicle skills programme

According to the Kovsie ACT team, the eco-vehicle skills programme helps students understand how their decisions and actions affect the environment, and further implores them to build on their knowledge and skills in order to address and combat complex environmental issues, while taking sufficient action to maintain its healthy state and secure it for the future. 

The skills development programme culminates in a race-day event where sustainable energy skills are put to the test. 
A certificate endorsed by the UFS and donor partner merSETA will be issued to students who have participated and who have been successfully trained and developed in the eco-vehicle skills programme, giving them a head start to the working world.

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.
