Ubuntu is a word we all know and, to some extent, relate to. Prof Francis Nyamnjoh aimed to delve and explore this African philosophy when he presented the 2019 Africa Day Memorial Lecture with the topic Ubuntuism and Africa: Actualised, Misappropriated, Endangered and Reappraised. 

The memorial lecture is hosted annually by the Centre for Gender and Africa Studies (CGAS) at the University of the Free State (UFS) to coincide with Africa Month celebrations. Prof Nyamnjoh holds a PhD from the University of Leicester in the UK. He is currently a professor of social anthropology at the University of Cape Town and has been a scholar in sociology, anthropology and communication science at universities in Cameroon and Botswana. The lecture took place on 22 May 2019 in the Equitas Auditorium on the UFS Bloemfontein Campus.

“When I saw the topic I thought this was very contemporary. We at the university decided to include the Ubuntu principle in our learning and teaching strategy,” said Dr Engela van Staden, Vice-Rector: Academic. 

Ubuntu as a binding factor for interconnectedness 

We live a world in which we cannot stand alone as the principle of Ubuntu tells us that we are who we are because of our interconnectedness with other people. “It is important to recognise that you stand on others to be tall,” said Prof Nyamnjoh. 

“We are the product of ongoing conversations on interconnectedness."

“I have argued that, in the spirit of Ubuntu, Africans, their identities and mobilities are part and parcel of the experience of being human in a world on the move. And their contributions are needed in today’s world more than ever. 

“I have broached the context of globalisation and histories of unequal encounters that have shaped relations in Africa and beyond under global capitalism."

“Even as it is increasingly seriously tested by opportunism, Ubuntuism, sometimes a reality and sometimes an ideal, brings hope and redemption, and offers a feasible framework for participatory and inclusive emancipatory social change,” said Prof Nyamnjoh.

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.
