Pulling valuable metals from e-waste makes financial sense

Electronic waste -- including discarded televisions, computers and mobile phones -- is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it's been unclear whether it's reasonable from an economic viewpoint. Now researchers report that recovering gold, copper and other metals from e-waste is cheaper than obtaining these metals from mines.
