Abstract

An apparatus for waste recycling that is suitable for residence building level in both volume and rate of supply of waste with a waste disposal and treatment container having the following parts: waste eliminator comprising a thermally and acoustically insulating casing with odour insulating raw waste receiving space; all-purpose shredder and crusher; crushed and/or shredded waste conveyor; liquid waste purifier; gasification plasma reactor; gas conveyor and purifier; slag collector; re-hydration means for re-hydrating solid waste in the gasification plasma reactor; and safety means. Each one of these parts is organized in fluid communication with its neighbor parts.

Claims

1. A waste disposal and treatment container for processing incoming waste, comprising:

a housing, the following elements located within the housing;

a shredder comprising a grainer screw and diagonally upward positioned turbinate screw,

a liquid collection container located below the shredder;

a plasma reactor located at a distal end of the turbinate screw which is upward of the grainer screw; and

a single or plurality of breathing membranes in communication with the plasma reactor;

wherein the grainer screw is configured to crush, grind and transport incoming waste into solid waste and liquid waste,

wherein the turbinate screw configured to transport the solid waste from the grainer screw to the plasma reactor; and

wherein the liquid collection container is configured to collect the liquid waste after it has been crushed by the grainer screw.

2. The waste disposal and treatment container of claim 1, further comprising a gas purifier, the gas purifier in fluid communication with the reactor through a gas outlet, wherein the gas purifier is configured to trap and filter out airborne solid contaminants to produce a purified gas.

3. The waste disposal and treatment container of claim 2, further comprising an energy generator in communication with the gas purifier, the energy generator receiving the purified gas from the gas purifier, and producing energy from the purified gas.

4. The waste disposal and treatment container of claim 3, further comprising a bottom accumulator in communication with the shredder.

5. The waste disposal and treatment container of claim 4, wherein the plasma reactor includes three plasma torches at the bottom of the reactor, and wherein the plasma reactor decomposes the incoming solid waste.

6. The waste disposal and treatment container of claim 5, wherein the decomposed incoming solid waste creates a molten or vitreous slag that falls to the reactor floor and passes through a lower outlet to the bottom accumulator.

7. The waste disposal and treatment container of claim 6, wherein the bottom accumulator is filled with water.

8. The waste disposal and treatment container of claim 1, wherein the waste disposal and treatment container has an entrance directly above the shredder for insertion of the incoming waste into the waste disposal and treatment container.

9. The waste disposal and treatment container of claim 1, wherein the liquid waste in the liquid collection container is purified by separating organic from aqueous phases of the liquid waste.

13. The waste disposal and treatment container of claim 1, wherein the breathing membranes include a filter configured to eliminate or reduce entrance of undesirable by-products into the plasma reactor.

14. The waste disposal and treatment container of claim 1, wherein the breathing membranes are in connection to corresponding valves.

10. A waste disposal and treatment container for processing incoming waste, comprising:

a housing, the following elements located within the housing;

a shredder comprising a grainer screw and diagonally upward positioned turbinate screw,

a liquid collection container located below the shredder; and

a plasma reactor located at a distal end of the turbinate screw which is upward of the grainer screw;

wherein the grainer screw is configured to crush, grind and transport incoming waste into solid waste and liquid waste,

wherein the turbinate screw configured to transport the solid waste from the grainer screw to the plasma reactor; and

wherein the steam gas and/or water vapor enhances and improves the decomposition process of the solid waste into the slag material,

wherein the sensors are configured to measure humidity, temperature, pressure, and

wherein data from the sensors is sent to a control unit and are used to calculate the amount of steam gas and/or water vapor needed.

11. The waste disposal and treatment container of claim 10, wherein the reactor is connected to a steam gas source through a single or a plurality of steam gas pipes.

12. The waste disposal and treatment container of claim 10, further comprising sensors positioned inside the plasma reactor.

15. A waste disposal and treatment container for processing incoming waste, comprising:

a housing, the following elements located within the housing;

a shredder comprising a grainer screw and diagonally upward positioned turbinate screw,

a liquid collection container located below the shredder; and
