Dr Martin Mandew believes that the devastating impact of the pandemic will be felt for quite some time.

It is not easy to discern the silver in the lining of the pandemic cloud that we have been living under over the past twelve months. I hazard to say that for those at the bottom of the socio-economic heap, those whose daily life is nothing but a gut-wrenching struggle to scrape together a semblance of a meal, talk of silver linings is foreign to their experience. The pandemic has shown just how low leaders can sink when elected public officials steal and redirect food parcels – meant for the poor and destitute – for their own personal consumption, for those close to them through family ties, through friendship and through political affiliation, or sell it for personal financial gain. The intended relief measures, designed to be non-partisan, are used instead to promote the socio-political divisions that already exist in the community. The unspoken mantra seems to be: If you look like me, if you think like me, if you believe like me, if you speak like me, if your political beliefs are like mine, only then can you expect me to do the public good for you and for your benefit that I have been elected to do, even though I get paid for carrying out this very important task. Talk of unity is rich in such an environment.

Nation-building
The devastating impact of the pandemic will be felt for quite some time. In the next twelve months we must, despite the enormous challenges ahead, re-imagine and craft a future of unity, where personal, political, ethnic, racial, gender, economic, and other differences will not stunt and sabotage efforts of socio-economic renewal. This Human Rights Month is a stark reminder for us to go back to our foundations as a South African nation. It is a time to press the reset button in the agenda of nation-building. Nation-building is not achieved through a fiat, a ‘let-it-be-so’ declaration. While taking the necessary steps to rebuild a battered economy, nation-building also entails making the necessary investments in social support to alleviate the impact of the pandemic on the most vulnerable in society, while also ensuring that the white-collared hyenas are kept at bay. The right to health care, food, water, and social security is enshrined in the Constitution.  

The future
Nation-building also entails making bold investments in education, taking care that as budgets are re-organised, re-prioritised and reduced, the education sector is not made a casualty of austerity measures. We must not falter to build our nation on a solid foundation of education, ensuring that we make the right investments and the required interventions in this very critical sector. There are components in the sector that are weak and glaringly under-resourced, such as early childhood development, as well as post-school technical and artisanal training. We need to strengthen these as part of building a firm foundation for our fledgling nation. This is a very important asurance for the future of our nation. Only an educated nation is best equipped to confront the challenges that lie ahead, such as those that the COVID-19 pandemic has thrust upon us. The right to education is enshrined in the Constitution.

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.
