Indonesia’s nickel business is booming. The metal is a key component in electric car batteries, but its success has a dark side: the country’s nickel mines and processing plants have a history of fatal accidents, with workers being run over by forklifts and burnt to death in smelter fires. 

Today on The Big Take Asia, host Janet Paskin speaks with Bloomberg Businessweek editor Matt Campbell about his investigation into the mines. He found that nickel sourced from these plants are present in the supply chain that feeds virtually every major seller of EVs, and is an indispensable part of the car industry’s green revolution.
