Abstract: A disposal method and disposal system for sharply reducing the residue and enhancing the sustainability and stability of disposal in disposal of organic waste are provided. The matter inside the solid phase decomposer is transported to a liquid phase decomposer I and is decomposed by land microorganisms at a solid phase decomposer III. The highly viscous products built up at that time are transported to the liquid phase decomposer I where they are dissolved in water and converted to sludge by aqueous microorganisms. The newly introduced organic waste is washed at the liquid phase decomposer I, transported together with the produced sludge to the solid phase decomposer III, and again decomposed by land microorganisms. For the transport of the matter inside the solid phase decomposer to the liquid phase decomposer I and the transport of the organic waste to the solid phase decomposer III, a solid/liquid circulator II having a twin screw structure is used.

Abstract: Method and apparatus for biologically oxidizing organic matter. Finely powdered organic matter is suplied into the top end of an upright, high reaction vessel (1). The vessel (1) has been filled up substantially completely by small balls, on the surfaces of which the matter to be oxidized is present in thin layers. By means of a conveyor (6) outside the vessel, the balls are transferred uppwards, whereby the balls in the reaction vessel (1) flow downwrds. Oxidizing air is blown uppwrds against the flow of balls, whereby in the upper section of the vessel, drying takes place in the first instance and then is formed an oxidizing zone automatically by microbial activity in a section, wherein the best oxidizing conditions are prevailing. Exhaust air is cleaned by means of ionic cleaners (14) and singlet oxygen generators (27) and oxidized matter is recovered from the bottom end of the reaction vessel.

Abstract: A U-shaped flexible tray for a compost bin having a rear wall, a front wall and a floor. The ends of the front and rear walls are releasably attached to upstanding mounting posts. Organic material is deposited into the bin and aerated, thereby forming compost. A tarp cover protects the compost from wind and rain.

Abstract: Initially, putrescent waste is deposited on a surface of a disposal volume which is partially composed of putrescent waste. A living system bio-converts at least a portion of the putrescent waste in the disposal volume, transforming the putrescent waste into waste residue.

A device for continuous bio-conversion of putrescent waste comprises a disposal track having lateral side walls and floor for containing the disposal volume. An excavation gap is associated with at least one of the lateral side walls for excavating waste material from the disposal volume. The excavation gap is positioned substantially below the living system so waste can be excavated simultaneously with bio-conversion.
