Generally, bio-wastes have high moisture. However, they have high caloric values if they are dried. Composting is one of the traditional recycling methods for them. It uses aerobic biological reactions. The high temperature that results from self-heat generation and the aeration for oxygen supply make the product dryer than the original. This phenomenon shows that effective drying can be achieved if this process is controlled well. However, it is not easy to find optimum operational conditions, because this process is very complicated with many environmental and operational factors. In this research, a simulation program that describes this process was developed. By comparing simulated results with the results of drying experiments, the validity of the simulation program is discussed.
