But back to glass recycling: Bottles and cans placed in the blue crates on the sidewalk are often picked up by resourceful homeless people, who roll through the streets with supermarket shopping carts packed to the brim and loaded with empties (Figure 1). They wheel the loot to the return machines located at some supermarkets and receive a few cents for each can or bottle. By the way, the amount of the refund depends on the state. In Michigan, oddly enough, you get a bit more than elsewhere. In an episode of the comedy show "Seinfeld," two of the characters try to drive a whole van full of recyclables from New York to Michigan because of this.
