Meal in a Jar
Omar-Raphael Tabengwa quoted Maya Angelou who said: “I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.”
Lunch and learning were reconciled at Joe Solomon School in Heidedal as part of Africa Day celebrations which were spearheaded by the University of the Free State’s (UFS) International Student Association. As part of the second annual Meal in a Jar project, 190 learners received a hearty meal and stationery packs on 23 May 2019.

In addition to being served rice, mince and vegetables, the Grade four pupils also had the opportunity to learn a bit of basic German and Dutch. “We broadened their minds by introducing them to our foreign exchange students,” said Omar-Raphael Tabengwa, Student Representative Council (SRC): International Students.

Give and gain 

Not only did the exchange expose learners to knowledge about other African countries that exceeds the scope of their curriculum, hence decolonising education from a grassroots level. This also gave international students the opportunity to engage with the community beyond the institution.

More than just a meal

The Meal in a Jar project also promotes environmental sustainability and teaches pupils the value of reusing and recycling. According to Omar: “The jars can later be used for different purposes such as a stationery holder, washing powder container or coin collector, based on an individual’s need.” 

Embracing value of Uhuru

The Meal in a Jar project’s theme for this year was Uhuru, which means “freedom” in Swahili. These are the ideals that the UFS Walk to Uhuru team stands for, an initiative that the project endorses.
 
Much like the Meal in a Jar project, the UFS Walk to Uhuru initiative advocates the educational rights of the less privileged and is currently raising funds to aid access to higher education. As part of the first leg of the walk, the Uhuru team took a 350km expedition on foot to the Qwaqwa Campus in March. They are expected to summit Mount Kilimanjaro in mid-June in an attempt to make R1million for the 2020 academic year.

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.
