Abstract
The primary thrust of this research was to design and construct a small scale laboratory reactor for the study of composting. The system was to be capable of simulating all aspects of a full scale composting environment as well as controlling all parameters of interest to the composting process. A secondary objective was to develop a kinetic equation, with a temperature dependent rate constant, to describe the rate of decomposition of volatile solids. All experiments were conducted using a simulated MSW formula provided by Procter and Gamble to maintain a consistent substrate. The duration of experiments was ten to fourteen days. Results indicate that the system is capable of reproducing the conditions found in a full scale composting system. Qualitative characteristics such as temperature profiles, conduction heat losses, and the progression of the composting reaction resemble those of large scale composting operations. For the model, some success was obtained by using a third order rate equation with respect to volatile solids, however, a better understanding of the metabolic processes which occur are required to adequately describe the variabilities found within the compost reactor.
