Abstract
A closed incubation system was developed for laboratory simulation of composting conditions at the interior of a large compost pile. A conductive heat flux control system (CHFC) was used to adjust the temperature of the internal wall to that of the compost center and compensate for heat loss. Insulated small vessels (400 cu cm) controlled by the CHFC system were compared with similar vessels maintained at 30 deg C (mesophilic) and 55 C (thermophilic), and with large vessels (10 000 cu cm) with and without the CHFC. The CHFC has particular utility in research requiring expensive chemicals or hazardous substances.
