Under complete mixing conditions, aerobic decomposition of mixed organic waste materials has been maintained continuously in the thermophilic phase in a 55-gal rotating drum. Temperatures ranged between 53 and 70 C. Raw material was added daily or every second day in amounts up to 18 lb per 100 lb of decomposing material. The weight of material removed ranged between 42 and 60% of the raw material added. Factors influencing the operation of the composting unit were studied in detail.
