Malawian Catherine Chaima and other African finalists will on Thursday (September 3) pitch their businesses for the chance to win £25,000 (K25 million) as the 2020 Africa Prize for Engineering Innovation in South Africa where UK Minister for Africa, James Duddridge will speak at the online event.
This is the first time that a Malawian has been shortlisted among the top 15, for her invention of an anti-bacterial soap made from natural agricultural waste and local ingredients using traditional knowledge.
The Africa Prize, founded by the Royal Academy of Engineering (delivery partner of the Global Challenges Research Fund), awards support to ambitious African innovators developing engineering solutions to local challenges.
For the past eight months, 15 entrepreneurs from Ghana, Kenya, Malawi, South Africa and Uganda have undertaken intensive training and mentoring from international business leaders and experts.
Acting UK High Commissioner to Malawi, David Beer, is quoted as saying in a statement made available to Nyasa Times that the Africa Prize is one of UK Government’s initiatives to support innovators across Africa.
“Scalable engineering solutions developed by ambitious African innovators who understand better the local challenges are key to achieving meaningful sustainable development.
“This is Africa’s biggest prize dedicated to engineering innovation, and is yet again up for grabs as applications for 2021 are now open. I encourage Malawians to apply,” he said.
Daughter to farming parents, Chaima grew up in rural Malawi, where groundnuts, cassava, banana and rice are popular crops.
Cassava peels and groundnut shells, however, pile up around farms as they are not seen as powerful composting material.
While banana leaves have many applications, the sheer volume of waste produced by this crop means mounds of dry leaves pile up.
As a chemical engineering student, Chaima focuses on re-purposing waste. During her final year, she turned her attention to the hidden properties of these agricultural by-products.
When she discovered that the leaves, shells and peels her parents threw away could be used to produce potassium hydroxide, the idea of Cathel soaps was born.
Cathel is an anti-bacterial soap created from natural agricultural waste and local ingredients using traditional knowledge.
Cathel soap — named after Catherine and her co-founder Ethel — also uses alternative anti-bacterial ingredients.
Several commercial soaps in Malawi rely on Triclosan, which not only kills harmful bacteria, but also bacteria required to maintain healthy skin.
For Cathel, the pair relied on traditional knowledge to identify natural ingredients such as Moringa, which has anti-bacterial properties.
Chaima hopes that the process she uses to make the soaps could establish an industry for agricultural waste to become a valuable commodity in Malawi.
