I have a worm composting bin right in my kitchen. Most of our kitchen refuse goes in there, and three months later I get rich worm castings in return, which I use as fertilizer in my garden. I can't believe how much less gets thrown out in the trash (and off to the landfill) now. People can do this even in apartments, with a little rubbermaid tub under their sink, under the bed, or in a closet.
