Terracycle: ecology, profits, and worm poop

Last weekend, a friend was telling me enthusiastically about a Princeton University drop-out who is using worms to turn food waste into plant fertilizer. The company, Terracycle, also recycles spray-bottles to package its product. Oddly enough, today I got an email from a totally unconnected friend, also raving about this same company. Looks like this small firm has somehow passed the media "tipping point" and is getting quite a bit of attention.
