Siphilangenkosi Dlamini, a fourth-year Governance and Political Transformation student at the University of the Free State (UFS), has been selected as one of South Africa’s 100 Shining Stars for 2022 by Inside Education, in partnership with the National Youth Development Agency (NYDA).

“I was more surprised than anything, but also very honoured,” he said. Dlamini, who made it into the Civil Society and Youth category, was chosen from a pool of 800 applicants for his remarkable work with the Help a Student initiative, and his services as the former secretary of the Southern Africa Scout Youth Forum. Although he could not attend the award ceremony held in Johannesburg on 20 October 2022 in person, Dlamini did receive a certificate. “What we do a lot of the time isn’t for recognition and it’s not necessarily for awards; but getting recognised motivates and assures me that the work we are doing has an impact,” he expressed.

The Help a Student Initiative

In the early stages of the COVID-19 pandemic, Dlamini recognised a rise in food insecurity among his fellow students. This set him on a path to source funding for the establishment of the project.

The Help a Student initiative aimed to curb food insecurity through the provision of food parcels to UFS students who were in need. The project, which ran from 2020 until early 2021, managed to distribute food parcels to nearly 250 students per month. The initiative did not only assist students who were on campus. The selected applicants who were at home or off campus also received digital food vouchers, which allowed for the purchasing of food items at Pick n Pay and/or Shoprite.

“Food security is something that I am passionate about. I grew up in a community where it was a massive issue.

However, in the past I was not empowered enough to know how to solve it. Therefore, when the opportunity presented itself to do something about it, I took it with both hands,” Dlamini expressed.

Although the recognition was not expected, Dlamini maintains that such platforms are imperative, as “they demonstrate that young people are doing something to improve the country in the different capacities they are in”.

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.
