The accelerated extraction of critical minerals such as lithium and cobalt is causing water insecurity and health risks, according to a report by the United Nations University Institute for Water, Environment and Health (UNU-INWEH), which refers to them as the “oil of the 21st century.” The high water consumption of mining operations limits access to water for other purposes such as agriculture, fishing, and human consumption. Furthermore, data from various regions in South Africa, Bolivia, and the Democratic Republic of the Congo reveal “widespread heavy metal contamination and exposure to toxic waste,” the report states. This leads to health problems including fetal malformations and chronic diseases, which disproportionately affect women and children.

In 2050, the total volume of waste electrical and electronic equipment in Europe will reach between 12.5 and 19 million tonnes, compared to 10.7 million tonnes – around 20 kilograms per person – in 2022, according to the report 2050 Critical Raw Materials Outlook for Waste Electrical and Electronic Equipment. Of this volume, only 54% was collected and treated correctly in 2022. Furthermore, of the one million metric tonnes of critical raw materials such as copper, aluminium and silicon present in this waste, less than half was successfully recovered, according to the report's estimates.
