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.

Chemistry Department expands its international footprint
2015-10-14

Prof André Roodt

Prof André Roodt from the Department of Chemistry at the University of the Free State has returned from a research visit at the St Petersburg State University in Russia. The research he conducted at the St Petersburg State University is part of a bilateral collaboration agreement between the University of the Free State and St Petersburg State University.

As part of his visit to Russia (from 17 to 28 September 2015), Prof Roodt presented a seminar at St Petersburg State University, and a lecture at the conference titled: International conference on Organometallic and Coordination Chemistry: Achievements and Challenges.

One of the local Russian newspapers quoted Prof Roodt as “world-renowned expert in the study of chemical kinetics and mechanisms of chemical reactions”. His presentation: Are detailed reaction mechanisms really necessary in (applied) organometallic and coordination chemistry' attracted great interest from the St Petersburg chemists.

The bilateral agreement came to life a year ago when the St Petersburg State University chemists won a grant in a competition to create an international research group, the International Laboratory of Organometallic Chemistry. The Laboratory is headed by Prof Vadim Kukushkin of the St Petersburg State University.

In addition to the employees of St Petersburg University, the research group consists of researchers from Portugal, Finland, South Africa, and Azerbaijan. Together, these groups of scientists are working on the problem of non-reactive metal activation molecules. The main theme of the research laboratory is in the catalysis and activation of metal inert molecules which then undergo significant change, and become meaningful to people chemicals, such as drugs.

As part of this initiative, a bilateral collaboration agreement exists between the St Petersburg State University and the UFS (Russian Science Foundation grant 14-43-00017). Students from our university have visited and conducted research at the St Petersburg State University while some of their students visit and research reaction kinetics at the UFS.

Prof Roodt hosted Valeria Burianova, a student from the St Petersburg University. During her visit at the UFS, she learned about response kinetics. A UFS PhD student, Carla Pretorius, joined the group in Russia where she conducted research on the intermetallic rhodium-rhodium interactions for the formation of nano-wires and -plates, with applications in the micro-electronics industry, and a  potential for harvesting sun energy.

The UFS Department of Chemistry extended its international footprint further with three of its students, Mampotsu Tsosane, Petrus Mokolokolo, and Tom Kama, returning from Switzerland after a six-week research visit in the group of Prof Roger Alberto from the University of Zürich. In return, Prof Roodt hosted a Swiss PhD student, Angelo Frei from Zürich, and taught him more about reaction mechanisms.
