In the DRC, the mining of cobalt is wreaking havoc in the country. It is home to more than half the world’s reserve, and could have been a large source of income. Instead, its mining is done by children (an estimated more than 300,000) and the proceeds fuel the ongoing conflicts. Cobalt is used in for instance electric cars, and as the demand increases, it will affect the DRC more and more. An alternative material would enable buyers to put pressure on the mines and to stop buying cobalt from war lords.
