Edward Kieswetter, newly appointed SARS Commissioner.
The Chairperson of the Council of the University of the Free State (UFS), Mr Willem Louw, extended a message of congratulations to Mr Edward Kieswetter on his appointment by President Cyril Ramaphosa this week as Commissioner of the South African Revenue Service (SARS).
Mr Kieswetter served as Deputy Chairperson of the UFS Council from 2008 to 2014 and was Visiting Professor at the university’s Business School until 2018.
“On behalf of the Council and the university community, I wish Mr Kieswetter well in his work as newly appointed SARS Commissioner. It is evident that the high-level selection panel made an exceptionally good choice for this crucial position. Mr Kieswetter’s vast experience as former SARS deputy commissioner, his subsequent track record of transformative leadership, and his experience in turning around a large institution will serve him well in this new role,” says Mr Louw.

Besides it mainly being used for sugar production, sugarcane has emerged as an important alternative for providing clean renewable energy. Dr Deepack Santchurn, who works in the sugarcane breeding department of the Mauritius Sugar Industry Research Institute (MSIRI), believes if he could contribute towards a more environment-friendly and renewable energy through the use of sugarcane biomass, he would consider himself having made a great leap towards a better world.
Sugarcane is mostly known and exploited for the sugar in its cane stem. According to Dr Santchurn it is not the only thing the crop does well. “Together with certain grasses, it is the finest living collector of sunlight energy and a producer of biomass in unit time. Sugarcane is now recognised worldwide as a potential renewable and environment-friendly bioenergy crop.”
Significantly more bioenergy can be produced from sugarcane if the production system is not focused on the production and recovery of sucrose alone but on the maximum use to the total above-ground biomass. Diversification within the sugarcane industry is of paramount importance.
He has been able to identify a few high biomass varieties that can be exploited industrially. One of the varieties is a commercial type with relatively high sugar and low fibre in the cane stem. Dr Santchurn explains: “Its sucrose content is about 0.5% less than the most cultivated commercial variety in Mauritius. Nevertheless, its sugar yield and above-ground biomass yield surpass those of the commercial varieties by more than 24%. The genetic gains compared to commercial varieties were around +50% for total biomass yield and +100% for fibre yield. Its cultivation is strictly related to bio-energy production and the extracted juice can be used as a feed-stock for ethanol and other high-value products.”
Dr Santchurn received his PhD at the UFS’s Department of Plant Sciences during the Winter Graduation Ceremonies in June this year. His study leader was Prof Maryke Labuschagne from the Department of Plant Sciences.
