NOVELTY - The processing system of organic waste has a water vapor supply unit to supply saturated water vapor of high heat in a container, a pressure-regulation unit (10) to control the pressure in the container by a shut-off valve and a stirring unit to stir the through-in waste material within the container. The stirring unit is provided with a shaft (7) which penetrates inside of the container. The waste material is stirred, thermally decomposed, carbonized and processed in a container by controlling the temperature at 230degrees C or more and pressure of 3 MPa.    USE - Processing system of organic waste is used for processing industrial waste such as excrements of sludge, waste plastics, wastepaper, wood chip, model-system solid unwanted material, animal-and-plant residue, dead-body of animal, rotten fishery products, agricultural products, meat, livestock farming waste material and infectivity of organic waste, and general waste such as domestic waste, classified organic refuse and foodstuffs residue, for producing fertilizer, feed and powder-or-pellet-form supplementary fuel for producing incinerated ash used as structural material (all claimed).    ADVANTAGE - The system enables efficient and economical processing of organic waste, without generating toxic substance such as dioxin.    DETAILED DESCRIPTION - The processing system of organic waste has a water vapor supply unit to supply saturated water vapor of high heat in a container, a pressure-regulation unit to control the pressure in the container by a shut-off valve and a stirring unit to stir through-in waste material within the container. The stirring unit is provided with a shaft which penetrates inside of the container. The waste material is stirred, thermally decomposed, carbonized and processed in a container by controlling the temperature at 230degrees C or more and pressure of 3 MPa. The pressure in the container is adjusted below atmospheric pressure to maintain the processed waste material in dried condition, and the processed waste material is discharged. The discharged process waste material is classified. The waste material is hydrolyzed, thermally decomposed, carbonized and processed by stirring the organic waste in hot and high pressure environment in a pressure-resistant container (1) of double-wall structure.
