E-waste is an interesting problem because of the mix of rare and toxic materials. A New Zealand startup is actually turning to biology for a solution. Using microscopic organisms they are able to more safely retreive the precious metals from discarded electronics. Via Business Insider:
Electronics are chock-full of gold, but getting it out is so difficult that most of it goes to waste.A New Zealand startup has found a way to extract gold from old circuit boards using inexpensive chemicals and microbes that absorb precious metals. The founders hope it will reinvent how the world deals with e-waste.
