This stainless compost bin by Kizmet Kare is perfect for holding all your organic matter, and keeping it out of the landfill, where it will produce methane, a potent greenhouse gas 30 times more powerful at heating our Earth than carbon dioxide.  Just layear your "green" organic matter with "brown" organic matter -- leaves, wood chips, old newspaper shreds -- add a little water, and "stir" once in a while.  The charcoal filter keeps any odors from escaping.
