A bathtub, outside, close to kitchen on a wooden frame with enough room underneath for a 10 litre container under the plug hole. Tiger worms (available commercially) convert food scraps and garden waste into worm casts. When it rains (or during a drought, when you pour water on it), the container fills with rich, almost odourless liquid fertiliser, which you pour on your garden. You're converting solid waste, which is largely cellulose, into liquid fertiliser. Even finely crushed egg shells are consumed. Read Worms Eat My Garbage by Mary Appelhof. So far we've disposed of hundreds of kg of solid waste like this and the tub isn't full.
