NatureMill Automatic Composter

Indoor compost without the odor

After a year of stinking up his kitchen, Russ Cohn finally figured out how to turn trash into fertilizer without the rotting stench. His NatureMill pumps fresh air into a basket that rotates organic waste at evenly timed intervals while maintaining a temperature of 140ºF. The heat, air and agitation destroy the compost-munching microbes responsible for emitting stinky methane. The machine is about the size of a small garbage pail, so it won’t hog space in your kitchen, and it accepts up to four pounds of organic waste a day, delivering a batch of high-nitrogen compost every two weeks—perfect for small urban gardens and flower beds. $300; naturemill.com
