Three composting techniques

Multiple-bin, large-scale composting
If you have loads of material to compost on a regular basis (and a strong way with a shovel), consider a multiple-bin system. This involves a large, lidded, rectangular bin divided into three compartments, each 1 to 1.2 metres square.

Wood is the most common material with wire mesh used for the interior walls to enhance air circulation. For easy access, the front panels should be either hinged or made so the slats can be removed individually as needed. Fresh material goes in the first bin; after it partially breaks down and shrinks, it is turned into the second bin; after shrinking further, it is turned into the third bin to finish off. This continuous process results in a nice steady supply of compost.
