where does it all go?

I just don´t understand recycling; I mean, I can understand recycling glass and metal and paper but then why, when you buy it back, does it costs twice as much. Why do I want to spend twice the price of fresh new paper on old uneven grey paper? Doesn´t make sense does it? The biggest question I have is where does recycled toilet paper come from? I don´t want my toilet paper recycled! I want it to go away and disappear somewhere in a big pipe. I certainly don´t want to see it back on the store shelf! Was it mine? How do they recycle it? Is there a wet and dry section down there somewhere? concerned - katrin
