Profiting from Recycled Junk Mail

Junk mail is advertising of one sort or another that arrives in your postal mailbox along with the mail you really want or need. It's impossible to eliminate all of it. They're ugly and a waste of ink and paper and we toss them in the trash at the first chance (some 4 million tons, nearly half of which is never opened). Even if you recycle there are still enormous environmental costs in terms of ink, energy to produce, deliver and recycle the paper.
