(PhysOrg.com) -- Many people throw out organic food waste. When I do this, I feel vaguely guilty, knowing I should probably compost it for my backyard garden. However, last time we tried to compost, the neighbors got upset. Composting works well in rural neighborhoods, but in a subdivision, your friends tend to notice the smell. Which is why it's very exciting that a new gadget has been introduced: NatureMill is a robot that composts your food indoors.
