100% e-waste, I'm sure. I also talked to a number of firms that will buy whatever you have, for pennies on the dollar, and then deal with it for you. Apparently things like memory chips can be unsoldered recycled pretty well.

This is another reason why I'm going with Dell these days, they have a program for recycling. Even if it isn't perfect, at least it is something...
