Seven Robots with Green Jobs

3.  Robot Composter for the Home

Back on earth, the workhorses of the robot world are the ones that collect and recycle waste, like the NatureMill food composting robot.  This one can mix, heat and aerate fresh scraps, automatically send them to a lower chamber to make room for more, and pop on a red light to signal that a fully composted load is ready – all without raising a stink.
