A fairly depressing topic, I admit that it hasn't really crossed my mind with what happens to old technology once it's thrown away until recently even though I'm surrounded by the stuff everyday. A lot of old tech ends up in landfill and as you're probably aware plastics and metals don't really degrade, at least when we throw away food it's going to rot and breakdown but throwing away a mobile phone is going to remain in the earth for a very long time not to mention the toxic chemicals it would release overtime. I've thrown away batteries away before in general waste bins and haven't really thought about the consequences of doing so. The point of this thread is to hopefully raise awareness of e-waste, search for local recycle centres and dispose the stuff properly. Here's a video I've found to give you a brief overview, here's more information from ifixit.
