Recycling has become part of everyday life in many parts of the world, but that usually means recycling things like plastics, glass and paper. We often forget to recycle valuable materials that we actually really need, like metals. A new report from the UN says less than one third of the earth’s metals have a recycling rate more than 50%.

That creates a big–and ironic–problem: the green technology we want to invest in for the future depends on those materials, so if we don’t do a better job recycling them, we might not have enough to produce the clean energy we want. The metals used in semi-conductors, LED lights, hybrid car batteries or magnets in wind turbines are all precious materials that are disappearing fast.

The message from the European Environment Agency is clear: improve the recycling rates. So how can we do a better job recycling important metals? Tell us what you think!
