Electronic waste — including discarded televisions, computers and mobile phones — is one of the fastest-growing waste categories worldwide.
Researchers report that recovering gold, copper and other metals from e-waste is cheaper than obtaining these metals from mines.
About 50 million tons of e-waste will be discarded around the world in 2018. This type of waste contains a surprising amount of metal.
For example, a typical cathode-ray tube TV contains almost a pound of copper and more than half a pound of aluminum.
