Dozens of global manufacturers found themselves on the defense when Amnesty International reported that the cobalt in some of their batteries was dug up by Congolese miners and children under inhumane conditions, reports The Wall Street Journal (Sept. 13, 2018). Many of the companies said they would audit their suppliers and send teams to Congo to fix the problem. But at a Chemaf-owned cobalt mine in Kolwezi, Congolese workers could be seen descending underground without helmets, shoes or safety equipment. The mine’s owner is part of the global cobalt supply chain for companies including Apple and VW.
Miners there were using picks, shovels and bare hands to unearth rocks rich with the metal. Water sometimes rushes into holes and drowns miners, and an earth mover buried one alive last year. “Of course, people die,” said the mine’s owner’s CEO. “This is really shitty work.” He called the miners “barbarians” and said Chemaf had resisted giving them safety equipment because they would sell it. “I don’t care about supply-chain problems,” he added. “That’s a problem for Apple and Samsung.”
Global demand is soaring for cobalt, which is used to conduct heat in lithium-ion batteries in products from smartphones to electric vehicles. Cobalt prices have more than doubled since 2016, putting Congo in the spotlight. It isn’t easy for global manufacturers to trace cobalt’s source in Congo, because it passes through multiple companies and countries. Some mining operations mix industrially produced and hand-dug cobalt. Samsung says it is aware some of the cobalt it gets from Chemaf is produced by the miners. If companies stopped buying it, said Samsung, it would put people out of work.
Amnesty recently applauded Apple’s moves to weed out child labor from its supply chain, saying it is “the industry leader when it comes to responsible cobalt sourcing.” Amnesty said VW hadn’t addressed whether certain companies in its supply chain received cobalt from Congo. Its report added: “Some of the richest and most powerful companies are still making excuses for not investigating their supply chains.”
Classroom discussion questions:
- Why is this a complex OM issue?
- Why is cobalt so important to supply chains?
