This technical note describes how to design a composting system and arrive at the essential end-products. A composting system is a means of turning garbage, animal manure, other organic wastes, and, in some cases, excreta into compost. Designing a composting system involves determining the method of composting, selecting a location, deciding on the configuration of the system, and determining the labor and tools needed to operate the system.
