Use less water and save more
Don't think twice about being water-wise

“Lift up the handle as soon as you flush. Don’t use the whole five litres at a go,” says Dr Cindé Greyling, who reckons we could save 25% of the water we flush down the toilet. Dr Greyling, who completed her PhD in Disaster Management at the University of the Free State (UFS), has spent years studying ways to shape the drought dialogue. Her voice is one that deserves our attention as citizens of this province.

Over the past five years the Free State has been experiencing heightened stress levels on reservoirs and dams due to the drought conditions induced by climate change. Since 2013 the issue has been worsening instead of improving.

Feasible water-conservation strategies
Students and staff members are advised to apply the same principle in the bathroom and kitchen alike by not letting the tap run while rinsing coffee cups. You could save a litre or two a day by (depending on how much coffee you drink and the number of cups rinsed) by quitting this bad habit. According to Dr Greyling, litter on campus is a secondary way of wasting water which many are unaware of. Litter blocks the drains and water which could have otherwise been recycled is lost in the process.

What do fellow Kovsies say?
Unamandla Mdlotshana, a third-year Actuarial Science student proposed eco-friendly adjustments that could potentially save litres of water on our campuses. He believes that using bottles to collect drinking water from taps, installing more water dispensers, and introducing hand sanitisers in bathrooms could drastically minimise water usage.

In Tebogo Chabangu’s view, taking shorter showers, turning off the tap while brushing your teeth, and making sure taps are properly closed are some of the ways we could be water-wise. For the Anthropology honours student being water conscious means changing habits on a daily basis.

Join us as we spread the message of reversing the effects of the drought by saving water prior to the Rector’s engagement with students at 11:30 on 08 March 2018 at the Albert Wessels Auditorium on the Bloemfontein campus.

Using sugar to make the world a sweeter place

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.
