NOVELTY - Waste material processing method, where the refuse is fermented at generation sites by treatment apparatus (1) by stirring with prefermented refuse, is new. The fermented refuse is transported to secondary concentration processing plant (2) where the refuse are concentrated and accommodated in pallets. The pallets are stored in three-dimensional shelf.    USE - For processing waste materials such as organic refuse from home, restaurant.    ADVANTAGE - Reduces collection cost of refuse as it is directly collected from each generation sites. Eliminates generation of rotten smell and environmental pollution. Enables performing reliable fermentation to produce stable compost without incineration, using the multistory shelf for composting effectively.    DETAILED DESCRIPTION - Waste material processing method, where the refuse is fermented at generation sites by treatment apparatus (1) by stirring with prefermented refuse, is new. Primary fermentation processing apparatus (1) is arranged at each generation site of organic refuse. The refuse is added to the existing fermented refuse in the decomposition tank and fermented by stirring. The fermented contents are collected and transported to a remote secondary concentration plant (2). Contents of suitable amount are left in the fermentation tank for fermenting the refuse for next cycle. Ejection mechanisms are arranged in each tank for discharging the contents to movable container for transportation, when the amount exceeds fixed volume in each tank. In secondary concentration plant, the contents are added at proper ratio with few additional unprocessed wastes fed through a set of hoppers which classify and feed the waste. The contents are stirred and collected at pallets, after specified period. The pallets whose contents are not completely fermented, are taken out and stored in a multistory shelf for composting.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of waste disposal system. (Drawing contains non-English language text).    Treatment apparatus (1)    Concentration processing tank (2).
