Find out how to build your own worm farm. In Australia, over half of the household material that end up at the tip is organic waste, and when it is buried can lead to groundwater contamination and the production of greenhouse gases - environmentally unsound and also wasteful because through natural processes this organic matter can safely and easily be converted into soil-building humus.
