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.
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.
Plastic waste is a big problem. Turning it into new plastic sounds like the obvious solution, but that's trickier than you think. Now two young entrepreneurs are trying a new kind of recycling that could do the job.
