Paper to be published in International Sugar Journal

Sep 18 , 2018

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

Mar 29 , 2018

It has been a greatest honour to have worked with COPESSA which was introduced to me by Cwenga. Even though I was with the organisation for a very short period of time I am proud to say I have gained a wealth of knowledge and experience which I will treasure.

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.
