The Department of Architecture at the University of the Free State (UFS) this year hosted the first entirely face-to-face Sophia Gray lecture since the COVID-19 pandemic.

Talking about Changing Landscapes, Practice and Pedagogy, Mpeti Morojele presented the Sophia Gray lecture – the biggest and most prestigious architectural lecture of its kind in South Africa – as the 33rd Sophia Gray laureate. 

Hailing from the mountain kingdom of Lesotho, Morojele established his design practice, the award-winning MMA Design Studio in Johannesburg, in 1995.

Local and international recognition

He is recognised for his work locally and internationally. Some of his projects include the South African Embassy in Addis Ababa, Ethiopia, the South African Embassy in Berlin, Germany, the Maropeng Cradle of Humankind World Heritage Site, as well as various Freedom Park projects, including Isivivane (the symbolic final resting place for South Africa’s fallen heroes), //hapo (telling the South African story of liberation and the triumph of the human spirit over three billion years), and Isikhumbuto (a place of remembrance, a gathering space at the top of a hill surrounded by the wall of names, sanctuary, gallery of leaders, and the Moshate).

His work engages the African landscape, incorporating indigenous knowledge and ritual to respond to and enhance the emerging African condition. 

Becoming conscious

In his presentation, Morojele explained his journey as an architect. As a student at UCT, he said he felt invisible because of the kind of architecture they were talking about; mostly architecture of the Western world. He elaborated on this point in his lecture, explaining about becoming conscious. 

“It took me back to the origins of humankind. I found it interesting to consider what the architecture at our origins was, and what the environment was in which we first became conscious of ourselves. It has been said that becoming conscious was the beginning of spirituality and art. The idea of origins interested me, and also how we as humans became conscious of ourselves and the space around us, until we achieve the state where we actually create these spaces for our own use,” he said.

As we evolved and became more conscious, we not only found objects, but placed objects in ways that commemorate our unity and spirituality, signifying society coming together to build something collectively. 

Symbiotic relationship with the environment

For Morojele, animism – the belief that inanimate objects have internal and distinct spiritual essences – also played a role in his designs. “It allows us to have a symbiotic relationship with our environment, as opposed to one where we exercise dominion over all things. Animism locates us in the environment as part of it rather than as outside observers of the environment.” 

The Kigutu International Academy, located on the Village Health Works Campus 100 km south of Bujumbura in Burundi and nestled in lush mountains overlooking the beautiful Lake Tanganyika, is an example of where he places humans close to the environment. Here he essentialises the architecture. This project, with its open spaces, also brought about the question of walls. Do they unite or do they divide?

Morojele remarked that architecture takes lessons from landscapes by giving shelter, security, and prospects of freedom. 

Re-establishing what it means to be human

His goal was to plant an idea in the minds of the architects who attended the lecture. Given where we are headed in the world, we need to re-establish what it means to be human; it is only when we recognised the humanity in all of us that we can begin to use architecture to unite societies. 

In order to do this, our focus needs to be less intellectual and more about how we as biological beings behave in environments; for example, do people feel alienated or do they belong in our spaces?

“These are the important things, I think, our architects need to talk about in the future,” he concluded his lecture.

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.
