To prevent production of odors and to decrease the fermenting period when compost is produced by preparing a fermenting box in such a manner that at least the side faces of the box comprise layers of packing material having air permeability and heat keeping effect or heat insulating effect.
This fermenting box for org. waste consists of a fiber layer 1 and a lath net 2, and the box has an upper face 6a of a deodorizer in the lower part of the box and a lower face 6b of a deodorizer on the upper part of the box. The fiber state of the fiber layer 1 is not limited and a felt is preferable considering its higher air permeability, heat keeping and heat insulating properties. In this case, a felt having about 5mm thickness like a carpet is preferably used. By using a felt, lots of air is included which has a function to keep or insulate heat and maintains the air permeability. Thus, decrease in temp. in the compost can be prevented so that fermentation can be accelerated not only in the vertical direction in the center part but near the side faces. By using advantages of a stand-type fermenting method with little generation of odor with this constitution, the fermenting period can be reduced.
