Student graduation

We are proud to offer our congratulations to Phumelele Motha for graduating from her Chemical Engineering degree at the University of Pretoria.


While she was with Cwenga, she worked in the laboratory verifying and investigating a hydrometallurgy project, recovering valuable metals from a waste stream. The use of ion exchange resins to reduce waste and recycle materials is a key area of research for Cwenga.

Paper to be published in International Sugar Journal

We are pleased that our paper written in connection with Tongaat Sugar, for the SASTA 2018 conference, will be published in the International Sugar Journal.

The paper, which details the ion exchange resin trial, covers both technical and commercial business sectors. Re-evaluating the status quo, and reducing commercial risk, in a method that was as low production risk as possible.

The publication in such a prestigious journal has been a very satisfactory conclusion to a long and intensive process, guiding the resin trial to a successful close.

COPESSA and Cwenga

I am taking away COPESSA’s vision of creating a safe and secure environment with me to my community and I promise to use this vision to build my own community. It is always nice to work with well envisioned people with positive energy that radiated in me.
