Enactus Qwaqwa Campus
Owning Their Future – Enactus students on the Qwaqwa Campus.

Empowered by the Enactus platform, a group of students on the Qwaqwa Campus are planting seeds of lifelong goodness in the Qwaqwa community.

Enactus is an international non-profit organisation that equips students to improve the world through entrepreneurial action by providing a platform for teams of outstanding students to create community development projects that put communities at the centre of improving their own livelihoods.

The group of seven students, namely Salima van Schalkwyk, Lehlohonolo Mokoena, Tubatse Moloi, Jennifer Links, Boikanyo Madisha, Bonagani Makwakwa, and Vuyo Mbamba, who are all pursuing undergraduate degrees in various disciplines, form part of Enactus.

Van Schalkwyk, the team leader and second-year Bachelor of Community Development student, said being part of Enactus has enabled them to make a tangible difference in the community around them.

“[As a team], we always assumed we knew what people go through on a daily basis, but we were in for a surprise. Despite the beautiful mountainous views of Qwaqwa, the people are in pain, one that is a cycle. When we look at all that we have discovered, all that we have heard and seen, we are moved to give the people of Qwaqwa a hand in being lifted to the surface.”

Leaving footprints of greatness for future generations

The team is currently competing in various competitions that seek to bring about social change. In 2021, the team was selected by MTN ICT as part of the top 12 nominees countrywide, receiving funding to develop an app that will assist students with mental health challenges. Apart from developing the app, they are also working on 7 Seeds, an agricultural enterprise that seeks to address the agricultural difficulties of a farm they identified in Qwaqwa.

Van Schalkwyk said they will be participating in the Enactus National Competition on 14 July 2022 and are gunning for the Enactus World Cup that will take place in Puerto Rico in October this year.

“Our vision as Enactus students is to create a better, more sustainable world for future generations. In the current economic situation our country is in, we believe that social entrepreneurship is the key to economic development and empowerment. Through Enactus, we hope to inspire many more students to submerge themselves in entrepreneurial activities. We live to leave footprints that lead to greatness for future generations,” she said.

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.
