Cwenga Lib has built a facility to recycle lithium-ion batteries that had previously been exported or dumped in landfills.
have become integral to everyday life, especially in South Africa, which, until March this year, had been subjected to severe load shedding.
Once collected, the batteries undergo shredding, which exposes the valuable metal-containing black mass at their core. From there, the black mass enters a proprietary hydrometallurgical process, where a blend of food-safe chemicals is used to leach out metals such as lithium, manganese, nickel and cobalt.
Cwenga Lib’s focus is on cobalt-containing batteries, also known as NMC batteries, but plans are under way to expand the process to handle all lithium-ion batteries, regardless of their chemical composition. This broader capability will be essential as the industry shifts towards new battery technologies with fewer cobalt components.
