New facility enhances responsible waste management at UFS

Chemical waste_web copy — 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.

UFS student makes breakthrough in the application of nanorobots

2005-04-21

A student from the University of the Free State (UFS) has made a ground-breaking discovery in the field of microbiology by uncovering a series of new compounds that may in future be used to lubricate man-made nanorobots.

Mr Olihile Sebolai, a full-time student at the UFS’s Department of Microbial- Biochemical and Food Biotechnology, made this discovery while working on his M Sc-study on yeast.

With this discovery Mr Sebolai will also be awarded six prestigious prizes during this week’s autumn graduation ceremony at the UFS. This university has recognised this exceptional achievement as a build-up to the celebration of national Science and Technology week next month.

Mr Sebolai’s dissertation on the yeast genus Saccharomycopsis Schionning has been published in an accredited international journal of repute.

“Words cannot describe how excited I am. I never expected to receive such recognition for my studies. I am humbled by all of this,” said Mr Sebolai.

The Lipid Biotechnology Group at the UFS recently discovered that some yeasts produce their own water-propelled capsules in which they are transported. These capsules have different shapes and resemble among others miniature flying saucers, hats with razor sharp brims etc. “In order to function properly, parts of the capsules are oiled with prehistoric lubricants – lubricants that are produced by yeasts and that probably existed for many millions of years as yeasts developed,” said Mr Sebolai.

According to Mr Sebolai these capsules are so small that approximately 300 can be fitted into the full-stop at the end of a sentence and are therefore invisible to the naked eye.

“With my studies I discovered many new compounds that resemble these prehistoric lubricants. These lubricants may in future be used to lubricate man-made nanorobots and are similar in size compared to yeast capsules,” said Mr Sebolai. The nanorobots are used to perform tasks in places that are invisible to the naked eye and could one day be used, among others, to clean up human arteries.

Mr Sebolai has been interested in the subject of Micro technology since he was at RT Mokgopa High School in Thaba ‘Nchu. “I was specifically interested in the many possible applications the subject has – in the industry, as well as in medicine,” said Mr Sebolai.

His next goal is to successfully complete his Ph D-degree.

The prizes that will be awarded to Mr Sebolai this week include:

Best Magister student at the UFS (Senate medal and prize);

Best Magister student in the Faculty of Natural and Agricultural Science and Dean’s medal at the same faculty;

The Andries Brink – Sasol-prize for the best M Sc dissertation in Microbiology;

The JP van der Walt prize for best M Sc dissertation in yeast science;

The Chris Small prize for an outstanding Master’s dissertation; and

Honorary colours awarded by the UFS Student Representative Council
