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 to host one of three world summits on crystallography

Prof André Roodt from the Department of Chemistry at the University of the Free State (UFS), co-unveiled a special plaque in Poznan, Poland, as president of the European Crystallographic Association, to commemorate the Nobel prize winner Max von Laue at a special Laue Symposium organised by prof Mariusz Jaskolski from the A. Mickiewicz University in Poznan.

Max von Laue, who spent his early childhood in Poznan, was the first scientist to diffract X-rays with a crystal.

2014 has been declared by the United Nations as the International Year of Crystallography, and it was recently officially opened at the UNESCO headquarters in Paris, France, by the Secretary-General of the UN, Ban Ki-moon. The International Year of Crystallography celebrates the centennial of the work of Max von Laue and the father and son, William Henry and William Laurence Bragg.

As part of the celebrations, Prof Roodt, president of the European Crystallographic Association, one of the three regional affiliates (Americas, Europe and Africa; Asia and Australasia) of the International Union of Crystallography (IUCr), was invited by the president of the IUCr, Prof Gautam Desiraju, to host one of the three world summits, wherein crystallography is to showcase its achievements and strategise for the future.

The summit and conference will take place on the Bloemfontein Campus of the UFS from 12 to 17 October 2014 and is titled: 'Crystallography as vehicle to promote science in Africa and beyond.' It is an ambitious meeting wherein it is anticipated to bring the French-, English- and Arab-speaking nations of Africa together to strategise how science can be expanded, and to offer possibilities for this as nestled in crystallography. Young and established scientists, and politicians associated with science and science management, are the target audience to be brought together in Bloemfontein.

Dr Thomas Auf der Heyde, acting Director General of the South African Department of Science and Technology (DST), has committed some R500 000 for this effort, while the International Union of Crystallography provided R170 000.

“Crystals and crystallography form an integrated part of our daily lives, form bones and teeth, to medicines and viruses, new catalysts, jewellery, colour pigments, chocolates, electronics, batteries, metal blades in airplane turbines, panels for solar energy and many more. In spite of this, unfortunately, not many people know much about X-ray crystallography, although it is probably one of the greatest innovations of the twentieth century. Determining the structure of the DNA was one of the most significant scientific events of the 20th century. It has helped understand how genetic messages are being passed on between cells inside our body – everything from the way instructions are sent to proteins to fight infections, to how life is reproduced.

“At the UFS, crystallography finds application in Chemistry, Physics, Biology, Mathematics, Geology, Engineering and the Medical fields. Crystallography is used by the Curiosity Rover, analysing the substances and minerals on Mars!

“The UFS’s Departments of Chemistry and Physics, in particular, have advanced instruments and important research thrusts wherein X-ray crystallography has formed a central part for more than 40 years.

“Crystallography has produced some 28 Nobel prize winners over the past 100 years and continues to provide the means for fundamental and applied research,” said Prof Roodt.
