Municipal solid wastes in Korea have physical and chemical properties suitable for composting, but composting has had little practical use in solid waste disposal until now because of a lack of understanding of process control. For practical use of composting, process control must be capable of maintaining good product quality while large quantities are composted in a short period of time. Ventilation control to maintain optimum temperature(Temperature Feedback Aeration Method) is reported to be convenient to operate. The purpose of this study is to analyze process efficiency and optimum temperature in the temperature feedback aeration method for composting of municipal solid wastes. The results of this study show that degradation and drying of substrate in the temperature feedback aeration method are higher than those in the constant aeration method. And the optimum temperature range for composting of solid wastes appears to be $50{\sim}54^{\circ}C$.
