ABSTRACT:
Method and apparatus is disclosed for composting material such as refuse and preferably a mixture of refuse and sewage sludge. The material is piled in such a way that transverse tunnels are provided whereby natural air circulation is obtained into and through the material remains undisturbed during maturation, thereby allowing aerobic bacterial fermentation to progress efficiently and without interruption. Because higher stacks and consequent greater volumetric capacity thereof is attained, greater efficiency of space utilization. The apparatus involves core structures which temporarily support the material and form the tunnels or ventilation passages therein, the core structures being removed when the material becomes self-supporting.
