TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The method involves using active oxygen supplying unit, and supplying the active oxygen by ventilation unit. The method involves setting predetermined time interval in the processing tank, and adding the organic waste into the processing tank. The method involves adding microorganism capable of producing superoxide dismutase (SOD), and aqueous solution, metal or metallic compound capable of supplying metal ion, where the metal ion produces Fenton's reaction. The method involves adding adjuvants chosen from copper, zinc and manganese to the processing tank. The method involves using magnetic field generation unit, and electron generation unit, where the active oxygen supplying unit makes ventilation path using the magnetic field generation unit, the electron generation unit emits electron to the ventilation path, and the ventilation path supplies air to the processing tank to produce a magnetic field. Preferred Microorganism: The microorganism capable of producing SOD is purple bacterium. Preferred Component: The support comprises chaff and/or wood chip material.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The microorganism activator is formed by using acid solvent containing one or more gelatinization suppressing agents chosen from acetic acid, ammonium acetate and ammonium chloride, adding magnesium aqueous solution and regulating pH using calcium hydroxide. Preferred Components: The metal ion is chosen from divalent iron ion, and monovalent copper ion. The silicon-containing material comprises magnesium or its compound. The silicon-containing solute comprises one or more substances chosen from intermediate product of cement, cement, blast furnace residue and coal ash. The solvent comprises diluted hydrochloric acid. The alkaline substance comprises calcium carbonate or lime. The silicon-containing solute is heat-processed at temperature below melting point of the silicon-containing material.
