NOVELTY - Composting of organic refuse ejected from home comprising adding oil (O) to compost raw material (CP) consisting of organic waste, and composting is started, where the fatty acid produced from oil receives beta-oxidation from carboxyl group side, and short intermediate material having 2 carbon atoms is produced, ammonia produced from raw material is neutralized with remaining intermediate material, and generation of ammonia smell is suppressed; where the generation of ammonia during compost operation is monitored, and additional dispersion of oil at raw material is performed, when generation of ammonia is sensed, is new.    USE - For composting organic waste such as organic refuse (claimed), ejected from home, industrial waste, and excrements of animals such as rabbit.    ADVANTAGE - The compost raw material is economically and reliably composted, and generation of ammonia smell is suppressed.    DETAILED DESCRIPTION - Composting of organic refuse ejected from home comprises adding an oil (O) of suitable amount to compost raw material (CP) mainly consisting of organic waste, such as an organic refuse, and composting is started. The fatty acid produced from oil receives beta-oxidation from carboxyl group side, and short intermediate material having 2 carbon atoms is produced. Ammonia produced from compost raw material is neutralized with remaining intermediate material, and generation of ammonia smell is suppressed. Generation of ammonia during compost operation is monitored. Additional dispersion of oil at compost raw material is carried out, when generation of ammonia is sensed. Therefore, compost method is enabled.    An INDEPENDENT CLAIM is included for compost apparatus (1), which has a treatment tank (11) integrated with device main portion, a stirring unit (2), which cuts back compost raw material in treatment tank by appropriate frequency, ventilation unit (3) for supplying oxygen at compost raw material in treatment tank, a substance-temperature measurement unit, an ammonia surveillance plane style (6), a dispersion unit (7) and a heater (74). The substance-temperature measurement unit measures temperature of compost raw material during processing. The style (6) monitors ammonia produced from compost raw material during processing. The unit (7) sprays oil at compost raw material. The heater heats oil.    DESCRIPTION OF DRAWING(S) - The figure shows the explanatory drawing of compost apparatus.
