Global Social Innovation Indaba
Panel discussion during the 2024 Global Social Innovation Indaba held at the University of the Free State, Bloemfontein Campus.

Insightful, thought-provoking and inspiring: These were some of the words used to describe the 2024 Global Social Innovation Indaba, which took place at the Centenary Complex on the University of the Free State’s (UFS’s) Bloemfontein Campus from 30 September to 2 October 2024.

The three-day conference was hosted by the global Social Innovation Exchange (SIX) in collaboration with the UFS, under the theme ‘People Powered Change’. The conference brought together leaders and innovators from South Africa and several other countries, including Louise Pulford, CEO of SIX; Markus Lux, Senior Vice-President at Robert Bosch Stiftung, and Desmond D’Sa from the South Durban Community Environment Alliance (SDCEA), among others.

In her opening address, Acting UFS Vice-Chancellor and Principal Prof Anthea Rhoda welcomed the guests and described the conference as an opportunity to “deliberate, debate, and dissect ideas around the all-important topic of harnessing people-powered change in order to build successful societies”.

Powering social change

As part of the conference guests engaged in a series of panel discussions and activities, and attended presentations on various topics.

D’Sa was one of the first speakers, delivering a keynote address titled ‘An activist guide to people-powered change’. He referred to moments throughout his career in which he has actively worked towards change in his community and beyond, and highlighted some of the work the SDCEA continues to do. Guests were also treated to a spoken word performance by Napo Masheane, Artistic Director at the Performing Arts Centre of the Free State (PACOFS).

Advocate Tembeka Ngcukaitobi touched on several points in his talk, such as what the law meant or means to indigenous people. He explored this by referring back to the colonialist era. Ngcukaitobi, who described law as the most ubiquitous and most stable concept that European settlers brought, indicated that it was brought in two faces: the face of justice, and the face of violence. Therefore, he said, “… the future of law that has been most enduring is the ability of the law to transform itself from violence to justice.”

Guests said they regarded the presentations and dialogues as insightful, and also highlighted their appreciation for being able to interact with the campus itself. This sentiment in large part stemmed from the attendees being split into smaller groups and taken to see different parts of the campus. They also got to see an exhibition exploring the role of art in social justice at the Department of Fine Arts.

Lessons from the conference

The last day featured a panel discussion titled ‘Challenging power dynamics and redefining global exchange’, which included an engagement session with the audience. Guests were able to reflect on the information they had acquired at the conference and challenged themselves to continue working towards change and innovation.

“What I learnt from these three days is that since we all want to do the right thing, we all know what the job that needs to be done is,” said Michael Ngigi, CEO of Thinkplace Africa. “As such, we need to be bold in going for that, and really push back on the status quo that is formed by the places we represent.”

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.
