If you are concerned about the environment but live in a city, have a small growing space or yard, or just don't feel like messing with large, outdoor compost bins like the compost strudel below, then bokashi composting might be the right method for you! 
Bokashi is a method of kitchen composting developed in Japan where the typical home is the size of a US bedroom and the typical kitchen could fit inside my shoe. Composting is facilitated by anaerobic microorganisms and takes place in a covered bucket under the sink.
I have been using this method off and on for several years. It cuts the amount of rubbish I need to cart to the street nearly in half, and eliminates nasty garbage odors.
