Students play leading role to ensure food security

17 June 2020 | Story Dr WP Wahl

The Division of Student Affairs (DSA) prioritises innovation to meet the challenges of food insecurity and malnutrition among students. To this end, several student volunteers and student governance structures are collaborating with the DSA on various initiatives.

During 2019, various conversations were held about the possibility of creating a health-promoting food environment at the UFS where students and staff are well informed and empowered to take appropriate action regarding their food and nutritional needs. These conversations resulted in an institutional strategy to address the food environment at the UFS. Student representatives serve on a technical committee that directs the implementation of this strategy. In this regard, several initiatives have already been launched.

Students from residences and other student communities have planted vegetable gardens on the Bloemfontein Campus with the assistance of KovsieACT and the Faculty of Natural and Agricultural Sciences. Students and staff are already harvesting and distributing vegetables to needy students every week. Measurements were put in place to continue this during the COVID-19 period. The following vegetables were planted: spinach, cabbage, beetroot, broccoli, cauliflower, and carrots.

Food parcels, donated by Tiger Brands and Gift of the Givers, are continuously handed out by DSA staff and student volunteers. In this regard, 540 food parcels have already been handed out on the Bloemfontein Campus during the COVID-19 period alone. During the same time, 117 students received food parcels on the Qwaqwa Campus. The innovation of this food parcel project rests on the fact that business, NPOs, UFS students, and DSA staff are collaborating to address food insecurity and malnutrition.

More collaborative initiatives will be implemented over the next 12 months. The DSA staff and students are already working with the Department of Dietetics and Consumer Sciences to create information packages about the preparation of low-budget nutritious meals.

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.
