Abstract
A rational strategy for composting is developed based on the interacting factors of microbial heat generation, temperature, ventilation, and vaporization of water. Because the heat generation results from decomposition of organic material, its rate should be maximized. Implementation is by means of an interactive ventilation control system to remove heat as needed to prevent a temperature increase to activity–limiting levels. The threshold to limitation is approximately 60°C. Since heat generation drives vaporization, the material dries as composting progresses. In contrast, current processes typically operate at 80°C; consequently, waste is decomposed slowly and little water is vaporized.
