NOVELTY - The system includes a crusher (2) that finely crushes the organic refuse (1) which has been categorized as fit for forming a high-quality compost, and a drying machine (3) that dries the crushed organic refuse, is installed in the organic refuse generation site. Some composters (5, 6) with which organic refuse conveyed from the drying machine is fermented and composted, are installed away from the refuse generation site.    USE - For producing high-quality compost from organic refuse ejected from restaurants, hotels, dining rooms.    ADVANTAGE - The processing burden of the organic refuse, in the refuse generation site, is reduced, since only a crusher and a drying machine with a comparatively simple operation, are provided in the organic refuse generation site, while installing the composters at a separate place. The installation can be made compact as compared to a case where organic refuse is composted directly, since dehydration and volume reduction of refuse, is attained by crushing and drying the organic refuse prior to the fermentation process. A heater for heating the compost in the fermentation-temperature control process, is made unnecessary, by using the exhaust gas of the incinerator. A compost suitable for being used as a fertilizer for horticultural application, is obtained since the amount of salt and pH are adjusted suitably.    DETAILED DESCRIPTION - The system includes a crusher (2) that finely crushes the organic refuse (1) which has been categorized as fit for forming a high-quality compost, and a drying machine (3) that dries the crushed organic refuse, is installed in the organic refuse generation site. Some composters (5, 6) with which organic refuse conveyed from the drying machine is fermented and composted, are installed away from the refuse generation site. An incinerator (4) which burns the inferior-quality organic refuse which is not fit for producing the high-quality compost, is installed at the center of the plant. The fermentation-temperature control of the composters is performed using the waste heat of the incinerator. The salt removal and pH adjustment of the compost are performed by blowing a pH regulator of high pH value, or salt-formation inhibitor, into the composer.
