> we can use landfills as mineral mines when that becomes economically viable. Is economics really the primary obstacle standing in the way of "mining" landfills? I've never been to one, but just trying to imagine it, I'd would be a hell of a lot more worried about diseases, toxins, and all the other awful stuff that ends up in landfills one way or another and that would stand in the way of separating the materials you want effectively/efficiently/cleanly/etc... the economics seem like the last concern.
