To minimize the generation factors of food refuse odors by a method in which cultivation microorganisms are selected appropriately, inoculated onto a medium, association-cultivated, and charged into food refuse to decompose/ extinguish the refuse.

Aerobic and optional liquid active microorganisms as cultivation microorganisms are selected appropriately, inoculated onto a medium such as sterilized/dried saw dust, rice bran, peat, wood chips, and porous ceramic balls, and association-cultivated, and the produced bio-chips, with a lid 3 opened by a spring type holder 4, are charged with food refuse into a decomposition/ fermentation tank 18 from the food refuse inlet 1 of an extinction apparatus. Setting at a low/ordinary fermentation temperature of 25-35°C is made by a heating wire 29 engaged/fitted on the peripheral surface of the tank 18 and the bio-chips are agitated with the food refuse to decompose/extinguish the refuse. In this way, the fermentation offensive odors of the refuse can be minimized.
