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.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
