Abstract: A new method for preparation of organic compost by incorporating zeolite into excretions from domestic animals. In the method, zeolite of about 10 to 30% relative to the total weight of excretions is homogeneously mixed and then piled for a predetermined period so that the water content of a surface portion of the pile of the mixture decreases to about 25% by weight or less, and the average water content of the entire pile decreases to about 55% by weight or less. The piled mixture is then supplied to a fermentation vessel in which it is scooped and turned over such that a high water content portion inside the low water content surface portion is divided into small masses and the low water content surface portion is divided into fine powders, so that the fine powders are spread around the small masses to thereby achieve effective aerobic fermentation in the vessel.

Abstract: An apparatus for producing well-fermented compost by achieving an aerobic fermentation of organic wastes, excretion, etc. The apparatus comprises a fermentation vessel of a rectangular configuration, a device for feeding slurry-like organic wastes within the base compost which has been piled in the vessel and for stirring the base compost and the slurry-like organic wastes, and a device for gathering an upper portion of the predetermined thickness of the fermented compost and for carrying the gathered compost out of the vessel. These devices are movably positioned on the top of the vessel.
