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.

Plant scientist, Prof Zakkie Pretorius, contributes to food security with his research
2014-08-26

 
Many plant pathologists spend entire careers trying to outwit microbes, in particular those that cause diseases of economically important plants. In some cases control measures are simple and successful. In others, disease management remains an ongoing battle. 

Prof Zakkie Pretorius, Professor in the Department of Plant Sciences, works on a group of wheat diseases known as rusts. The name is derived from the powdery and brown appearance of these fungi.

Over the course of history wheat rusts have undergone what are notoriously known as boom and bust cycles. During boom periods the disease is controlled by means of heritable resistance in a variety, resulting in good yields. This resistance, though, is more often than not busted by the appearance of new rust strains with novel parasitic abilities. For resistance to remain durable, complex combinations of effective genes and chromosome regions have to be added in a single wheat variety.

In recent years, Prof Pretorius has focused on identifying and characterising resistance sources that have the potential to endure the onslaught of new rust races. His group has made great progress in the control of stripe rust – where several chromosome regions conditioning effective resistance have been identified.

Dr Renée Prins of CenGen and an affiliated UFS staff member, developed molecular markers for these resistance sources. These are now routinely applied in wheat breeding programmes in South Africa. In addition, Prof Pretorius collaborates with several countries to transfer newly discovered stem rust resistance genes to wheat, and in characterising effective sources of resistance in existing wheat collections.

His work is closely supported by research conducted by UFS colleagues, students and other partners on the genetics of the various wheat rust pathogens. These studies aim to answer questions about:
• the origin and relatedness of rust races,
• their highly successful parasitic ability, and
• their adaptation in different environments.

The UFS wheat rust programme adds significantly to the development of resistant varieties and thus more sustainable production of this important crop.
