Excellent start for Kovsies and Mamburu
Khomotso Mamburu (right on photo) has been the star for the Kovsies in their first two matches of the Varsity Netball Series.

The Kovsie netball team – Khomotso Mamburu in particular – has had an excellent start to Varsity Netball 2018. Mamburu, who plays goal defence and wing defence, became the first Kovsie player in the history of the series to bag two Player of the Match awards consecutively.

The Kovsies won both their opening matches with ease. Their big win over the defending champions, Tuks, by 68-43 in August, was the biggest defeat the Pretoria students have ever suffered in the competition. 

The Kovsie netball team, who are the two-time champions of 2013 and 2014, also earned a bonus-point victory in August when they drubbed the University of Johannesburg by 69-29. The Kovsies are now joint first on the log.

They faced the Vaal University of Technology in the Callie Human Centre this past Sunday, followed by a meeting against the University of the Western Cape on Monday afternoon.

Khomotso, an LLB Law student who was voted Player of the Varsity Series last year, has received three Player of the Match awards, which is just one less than the Kovsie record of four held by Karla Pretorius, playing for the team from 2013 to 2015. 

Meanwhile Karla, a postgraduate student, is making huge strides overseas. Her club, Sunshine Coast Lightning, won the Australian league for a second consecutive year on Sunday. She was named in the Team of the Tournament as goal defence. Karla finished the tournament with 50 incepts, which were the most in the tournament.

UFS research could light up South African homes
2016-01-21

Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology, is using her research to provide solutions to the energy crises in South Africa.

A young researcher at the university is searching for the solution to South Africa’s energy and electricity problems from a rather unlikely source: cow dung.

“Cow dung could help us power South Africa,” explains Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology.

Reitumetse’s research is trying to understand how the bacteria works that is responsible for producing biogas.

“Biogas can be used for cooking, heating, lighting and powering generators and turbines to make electricity. The remaining liquid effluent can fertilise crops, as it is high in nitrogen, phosphorus and potassium.”

By using cow dung and food waste to produce biogas, we will be able to lower greenhouse gases.

Biogas is produced in a digester - an oxygen-free space in which bacteria break down or digest organic material fed into the system. This process naturally produces biogas, which is mainly a mixture of methane and carbon dioxide.

“Many countries, such as Germany and the United States, have begun generating electricity from cow dung and food waste, through a process known as biogas production. In South Africa, a number of industries, including waste-water treatment facilities and farms, have caught on to this technology, using it to generate heat and to power machines.”

Until recently the world has relied heavily on electricity derived from fossil fuels such as coal, natural gas and oil. Once these fuels have been extracted from underground reservoirs, they are treated or cleaned, transported to power plants and transformed into the electricity that will reach your house. Fossil fuels are considered a ‘dirty’ energy source which gives off greenhouse gases when burned. Those gases are the major contributing factor to climate change.

“We know very little about the interaction of the bacteria inside the biogas digester. To use biogas as a sustainable fuel source, we need to understand and describe the bacteria population and growth dynamics inside the digester to produce biogas optimally. Currently we are testing a variety of feedstock, including bran, maize and molasses, for biogas production potential, as well as optimising the conditions leading to maximum biogas production. We are also exploring the potential to use the effluent as fertiliser on local farms. The ultimate goal is to have biogas systems that will supply our university with clean energy.”
