Ever consider setting up an indoor red wiggler bin? I've found that the time for finished compost is shortened. No odors, easy to maintain, and it creates thousands of pets. Hard to name them all, or really know who is who, but it works.
As a bonus it gets most kids real excited and most adults wondering about your sanity.
The worms are also good food for aquatics in the home.
