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.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
