Prestige Lecture by Justice Albie Sachs

Invitation

Who actually wrote the Constitution?

The Dean of the Faculty of Law, Prof Serges Kamga, invites you to a Prestige Lecture which will be delivered by Emeritus Constitutional Court Justice Albie Sachs.

Date: 30 October 2024

Time: 17:30

Venue: Equitas Auditorium

RSVP: Before 20 October 2024 (RSVP here)


Albie Sachs is an activist, writer and former judge on the Constitutional Court of South Africa (1994 – 2009). He began practising as an advocate at the Cape Bar at the age of 21, defending people charged under the racial statutes and security laws of apartheid. After two spells of being detained in solitary confinement without trial, first for five months, then for three months, he went into exile in England, where he completed a PhD at Sussex University. In 1988, he lost his right arm and his sight in one eye when a bomb was placed in his car by South African security agents in Maputo, Mozambique. After the bombing, he devoted himself to the preparations for a new democratic constitution for South Africa. When he returned home from exile, he served as a member of the Constitutional Committee and the National Executive of the African National Congress until the first democratic elections in 1994.

Sachs is a Board member of the Constitution Hill Trust, which promotes constitutionalism and the rule of law. He has travelled to many countries sharing South African experiences that might help heal divided societies.

He is the author of several books, including The Jail Diary of Albie Sachs, Justice in South Africa, Sexism and the Law, Soft Vengeance of a Freedom Fighter and The Strange Alchemy of Life and Law. His latest books are We, the People: Insights of an activist judge (2016) and Oliver Tambo's Dream (2017). He received an honorary doctorate in Law from the UFS in 2022.

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.
