摘要： A method and an apparatus is provided for aeration of organic material, wherein the organic material undergoes an aerobic composting process, such that air is caused to evenly penetrate the organic material. The organic material is first sealed in a vessel. Air is then delivered to the contents of the vessel such that an air pressure of from about 1 to about 1000 kPa above atmospheric pressure is maintained in the vessel. A pressure differential initially forms and is then allowed to equilibrate over a period of time, in which time air flows from areas of high pressure to areas of low pressure in the organic material thus ensuring that aeration is evenly distributed throughout the organic material.

摘要： An organic waste material treatment process comprising subjecting the organic waste material to conditions under which anaerobic digestion occurs followed by conditions under which aerobic composting occurs. Preferably, the organic waste material is pre-conditioned before anaerobic digestion by subjecting the organic waste material to aerobic composting conditions to facilitate a rise in temperature of the organic waste material. The treatment process is conducted in a single vessel, wherein air and water are evenly distributed to the contents of the vessel. A plurality of vessels may be interconnected, such that water may be extracted from one vessel, whose contents have undergone anaerobic digestion, then recirculated to an interconnected vessel to facilitate conditions for anaerobic digestion of the contents of the interconnected vessel.
