Thank you very much to Sora for finding this article for me on some good, old-fashioned Trashonomics.

“Making plant food from worm poop and packaging it in reused bottles, Tom Szaky created a truly beautiful business model. ”

“Worms, after all, do not charge for their labor, never take a day off, produce their body weight in waste every 24 hours, and–since they copulate while they eat–double their numbers every three months. They are also content to dine on stuff that might otherwise go into landfills. ”

And, of course, it has the word poop in it.
