The worms eat the waste and excrete it as 'castings' - a fancy name for worm poo. It can go directly onto your pot plants or garden, or be made into home-made liquid fertiliser, simply by mixing it with water till it looks like weak tea.
A wormery is a self-contained composting system that retains most nutrients for reuse. The digestive system of the worm helps produce concentrated compost with about four times the plant nutrition of ordinary compost.
You'd be surprised how much waste worms can get through. In fact, even a small wormery can dispose of all the fruit and vegetable waste produced by a household of four. The worms compact the rubbish they eat, down to a tenth of its original volume.
