Tinus Viljoen (second from the left) is responsible for waste management at the university. Here he is pictured at the new chemical waste facility on the western side of the Bloemfontein Campus. With him, on his left, is Nico Janse van Rensburg, Senior Director, University Estates; Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences; and on the far right is Benedict Mochesela, officer at University Estates.

A new chemical waste facility on the western side of the Bloemfontein Campus started functioning in July 2021 and will enhance the safe storage of hazardous materials on campus.

Since the safety of its staff and students are a key priority for the university, as stipulated in its strategic plan, a facility such as this plays an essential role in reducing any health risks and even the possibility of an explosion.

Tinus Viljoen, a Lecturer in the Department of Genetics, concurs that this facility makes the university a safer place because there are less toxic and flammable waste lying around in the labs. 

Besides his role as lecturer, he is responsible for waste management, including the collection of hazardous waste internally, classifying it, and arranging for it to be collected by accredited waste companies. 

A safer space

Waste previously stored in the Genetics Building is now kept at the new facility. Viljoen is of the opinion that this new space is safer because fewer students and staff have access to the western campus. “The chemical waste tends to smell, and on this part of the campus it is out of the way,” he says.

He also says that it helps to have a central place to store the waste, because of logistical reasons. “It makes the overall waste management easier.”

It is mainly inorganic and organic liquid/solid waste, contaminated glass, contaminated solids (e.g., filter paper and gloves), acid waste, and expired chemicals that are stored at the facility.

Adhering to legislation

He explains that he is notified by departments in the Faculty of Natural and Agricultural Sciences when they have waste to collect and that he then collects it on Fridays.

Viljoen continues: “The chemical waste is then classified according to the various waste streams and stored in large 210 l drums. When the drums are full, I contact an accredited hazardous waste company to remove, transport, and dispose of the various waste according to strict legislation, constituting the National Environmental Management Act (Act 107 of 1998), the National Environmental Management: Waste Act, 2008 (Act 59 of 2008), the Hazardous Substances Act (Act 5 of 1973), and the National Road Traffic Act, 93 of 1996 (NRTA).”

“The majority of the waste is transported to a hazardous landfill in Gauteng and the rest are incinerated,” he concludes.

Tiny microbes may solve large problems of water contamination, says Prof Esta van Heerden

Small solutions for big problems

According to Prof Esta van Heerden, professor in the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), this might hold some truth in current terms of water treatment strategies for waste and industrial effluents.

“There is little doubt in popular literature that eminent water crises are looming, not only with respect to the supply, but quality and effectiveness of various treatment options as well. The UFS’s Department of Microbial, Biochemical and Food Biotechnology is partnering with the Technology Innovation Agency to evaluate water treatment technologies that are applied worldwide and to extend these new or adapted options to innovative and interested clients in South Africa,” says Prof Van Heerden.

“The research focuses on using extreme microbes to tackle big contaminations and the results are amazing,” says Prof Van Heerden.

These microbes are fast becoming the stars on sites and developing these exciting systems allows for greener treatment options. It is fascinating that they can deal with metals, including chromium and uranium, cyanide, petroleum and diesel.

Of utmost importance is the development of a treatment for acid mine drainage.

“Interests have been overwhelming and thus far partners have allowed pilot scale development on their sites with very promising results. These initiatives are driven by responsible partners who strive to be innovative and develop sustainable technologies for good quality water that can be released in the environment,” Prof Van Heerden says.

The research group has set up a pipeline to serve the water communities’ needs. It provides an accessible toolkit for water analysis. A tailor-made treatment option is also developed and showcased in the laboratories. It has the added benefit that Geosyntec Consultants, USA, will ensure faster roll-out by sharing their vast experience on any related aspects.
