Michael Munger, at EconLib, analyses the 'logic' behind recycling. Sample:
"There is a simple test for determining whether something is a resource (something valuable) or just garbage (something you want to dispose of at the lowest possible cost, including costs to the environment). If someone will pay you for the item, it's a resource. Or, if you can use the item to make something else people want, and do it at lower price or higher quality than you could without that item, then the item is also a resource. But if you have to pay someone to take the item away, or if other things made with that item cost more or have lower quality, then the item is garbage.
If yard waste were a resource, then trucks would drive up and down streets in your neighborhood, bidding up the price of your bagged grass clippings. That doesn't happen. Ipso facto, yard waste is garbage. No amount of wishful thinking, or worship of nature as a goddess, can change this basic calculus."
