The University of the Free State (UFS) Wool Wise Community Project was recognised for its innovative use of wool, receiving accolades at the OVK Innovation Competition held in conjunction with the Karoo Winter Wool Festival in Middelburg from 13–16 June 2024.According to Carien Vorster, project manager from the Department of Sustainable Food Systems and Development, participants were tasked with crafting practical items from wool. Their creativity shone through in their design of a lampshade, earning them second place. Doretha Jacobs, a lecturer in the Department of Sustainable Food Systems and Development, focused on making felt from Dorper fibre, noting that while Dorper sheep are primarily bred for meat, they sought to repurpose fibres that would otherwise be discarded.

The team achieved third place with their cushion, featuring a front made entirely of merino wool felt and a back crafted from upholstery fabric. “Each cushion contains a 100% duck feather inner, and their uniqueness lies in the hand-dyed wool and hand-placed designs on each felt piece,” explains Vorster.

Other notable entries from different teams included a duvet inner, shoe insoles, and oven gloves. The top prize went to a hand-felted coat.

Community project empowers local women in wool craft

The UFS Wool Wise Community Project originated as a spin-off from the Regional Universities Forum for Capacity Building (Ruforum) project, initiated in 2019 by the UFS Department for Sustainable Food Systems and Development.

According to Vorster, the Ruforum project encompasses various components such as research, farmer support, and community development, with a particular emphasis on community upliftment programmes. "Since 2019, we have conducted numerous wool workshops and training sessions where local women have participated to learn about wool processing," she explains.

"From these events, we identified women who are now integral to our programme. Their skills range from sewing, felt making, and hand embroidery, to knitting."

The project features eight women who create diverse products from scratch: Elizabeth Mnwana, Emily Segame, Georgina Collins, Maserame Sebonyane, Nelly Olayi, Sarah Lenong, Sophia Mekhoe, and Ntabiseng Ndabeni.

She emphasises that the project also manufactures conference bags for various events and stands as one of UFS's most successful community initiatives. "Ultimately, this project has the potential to become self-sustaining, with proceeds supporting the salaries of the eight women," Vorster concludes.

Competition boosts visibility and market reach

Participating in initiatives like the OVK Innovation Competition motivates them to stay current and benchmark their efforts against other businesses or individuals involved in felt product creation.

"Winning a competition can also significantly uplift team morale," remarks Vorster.

"Securing second and third place in this competition translates to increased visibility and marketing opportunities for us. This is crucial as we aim to expand our market reach and establish a sustainable income stream for the project," she concludes.

Carbon dioxide makes for more aromatic decaffeinated coffee

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way.

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night.

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants.

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
