ABSTRACT:
In a stationary upright cylindrically shaped container, organic waste materials are passed downwardly from an upper inlet opening to a lower outlet opening. At the same time air is passed in counterflow upwardly through the downwardly flowing body of waste materials being converted into compost. The air supply means at the lower end of the container are divided into sector-shaped parts, and the compost is conveyed to the outlet opening from each of the sectors of the body so that the moisture content of the material leaving each sector can be checked. Air is introduced, in turn, into the lower end of each sector within the container. The amount of air introduced into each sector is regulated in accordance with the moisture content of the material discharged from that sector.
