Lithium-ion battery recycling with Cwenga Lib

20240514_091520_resized_1.jpg

Cwenga Lib has developed a Lithium-ion battery recycling process over the last 2 years that utilised food grade and environmentally friendly reagents at ambient temperature to reduce the electrical energy inputs that are associated with costly pyrometallurgical processed. The intention is to recover and separate the metals within the batteries to a quality where they can re-enter the market as raw materials thus completing the circular economy.

Congratulations to Mantsha Emeldah Mathibela, our Laboratory Technician, who received a National Diploma In Analytical Chemistry  from the Tshwane University Of Technology . Mantsha is pursuing an Advanced Diploma In Analytical Chemistry at the moment.

She is currently working on a project, focused on  the removal of nitrates from water using Ion Exchange resin where the effect of functional groups in anion exchange resin are investigated. Mantsha is passionate about her work and looks forward to working on more projects. The dreams is to  obtain her PhD in chemistry someday. 

Student graduation

A very enthusiastic well done to Lesego Siwela, who graduated from the University of Pretoria last month with her Batchelor of Engineering (metallurgical) degree.

Although it has been an interesting challenge to mentor a student throughout lockdown, she has done admirably. Lesego worked on an incredibly varied set of projects, bouncing from hydrometallurgy (copper and gold recovery and cobalt leaching) to food processing (colour removal from sugar and inversion of glucose syrup) to development of analytical methods for our internal laboratory.

Cwenga granted essential services status

Cwenga Technologies has been granted essential services status by CIPC as a supplier into the food production and water purification industries. This means that during the COVID-19 South African lockdown, we are able to continue all our functions. 

While most of what we do can be achieved remotely, it is a relief that we can continue to support our customers throughout this time in whatever capacity is necessary.
