Basic Equipment
Turning Units
A turning unit looks like three holding units placed side by side. Each unit should be a cubic meter. Leave one side open or build a gate along one edge for easy access. Fill one bin at a time, using a mixture of high‐nitrogen and high‐carbon materials. For rapid composting, turn the contents into the empty adjoining bin every week or two, or each time the temperature begins to decline.
A pile that is kept "hot" like this should produce compost within a couple of months, although an additional period of curing is necessary before the compost is used for growing plants. The final bin provides the space needed for curing while a new batch of compost is started in the first bin.
