NOVELTY - Moisture content contained in organic waste (1), such as livestock excrements and organic refuse is evaporated using hot air produced in hot air generation chamber. Curing fermentation of organic waste is then carried out. Odor gas produced during fermentation is collected and deodorized with a deodorant, and composting processing of organic waste is enabled. The deodorant having reduced deodorizing capability after deodorization of odor gas is burned, and resulting combustion heat is used as heat source for hot air required for preprocessing.    USE - Composting processing of organic waste e.g. organic refuse and livestock excrements.    ADVANTAGE - The composting processing of organic waste is economically carried out. The combustion waste is used effectively without discarding.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composting processing apparatus. The apparatus has a drying machine (2), a deodorizing tank (4), curing fermentation machine (3) and biomass hot blast generator (5). The drying machine carries out ventilation of organic waste in hot air, and evaporates moisture content of waste. The fermentation machine carries out curing fermentation of moisture-removed waste. The deodorizing tank collects odor gas produced during fermentation, and deodorizes with deodorant. The hot blast generator uses deodorant having reduced deodorizing capability after deodorization of waste, as biomass fuel.
