The NatureMill PRO is an indoor composter that turns your food scraps into rich, healthy compost in just a couple of weeks. You can convert up to 120 pounds of food waste a month into compost producing only a mild smell “similar to sourdough, mushrooms, or damp straw.” I’d presume that’s mostly when the food bin is open, since a carbon filter cleans the air vented by the built-in fan. You could also use the unit outdoors.
Three models are available: the NatureMill plus for $300; the NatureMill PRO with a foot pedal bin lever and steel chassis for $400; and the “Pet-friendly” NatureMill which can accept pet waste in addition to food waste.
Of course you could ditch the electricity use entirely to build an at-home worm composting box. And a starter batch of worms costs just $10.
