I have no idea how much e-waste results from a phone. How many materials are mined to make the metals? How much energy was needed to manufacture the chips?

At first glance yeah, a phone has much less e-waste than a laser printer. Is this true though? Yeah, the laser printer takes up more space in a landfill. But what about everything that went into making the phone, and the waste resulting from these processes? Maybe the lithium ion battery alone is considered much worse waste than anything in the printer.

I have no idea. It would be interesting to see something that attempts to tally these things.
