Abstract: It is well known that energy, in the form of heat, is released through microbial conversion of chemical species in a compost system. This heat energy is a major factor in the performance of the compost system and the effects of climate, especially subfreezing temperatures, may require engineering controls. This report reviews the literature on the effects of cold climates on composting. The suitability of current compost system designs for remediating explosives-contaminated soils in cold regions is discussed and a theoretical heat balance is performed. Results indicate that cold climate composting may be performed with appropriate controls; however, lack of operational data for analysis requires reliance on theoretical models that may be overly simplified. The complex relationships between physical parameters in compost systems are also discussed.
