Whether hard drives or electric motors, rare earth elements play a key role in a range of technologies. The metals mostly come from China. To ease dependence, researchers at the RWTH Aachen University are working on recycling the precious elements.
As the e-mobility drive gets stronger, it's already clear that there will soon be huge piles of discarded electric batteries. Some of the materials used to make them are clearly too precious to be thrown away, though.
This week on Eco Africa we visit a startup combating Senegal's slash and burn farming traditions, see how to turn scrap metal into art in Kenya and look into the possibilities of using hydrogen to fuel the world.
E-waste is a global problem, while the mining of fresh resources for electronics leaves devastation in its wake. And yet, the more cutting-edge our devices, the harder they are to recycle.
On this week's Eco Africa, we check out an eco-friendly twist on hair extensions in Kenya, turning recycled plastic into roads in South Africa and protecting lions in Tanzania.
