Abstract

A system and method for processing solid waste disposal includes a hydrolyzer (80) and a injection assembly (30) for transferring waste to the hydrolyzer (80). The injection assembly (30) includes a sleeve (40), in which waste is compressed with a ram (37), and a movable gate (52), which opens to allow the compressed waste (68) to exit the sleeve (40) and enter the hydrolyzer (80). The hydrolyzer (80) includes a pressure vessel (84), a rotating shaft (108) contained within the vessel (84), and agitates attached to the shaft for moving and processing the material through the hydrolyzer (80).

Description

FIELD OF THE INVENTION

[0001] The present invention relates to solid waste disposal, and, more particularly, to apparatuses, systems, and methods for transforming solid waste into useful products, including a reusable, treatable, or readily degradable material. BACKGROUND OF THE INVENTION

[0002] Solid waste disposal can generally be defined as the disposal of normally solid or semi-solid materials, resulting from human and animal activities, which are useless, unwanted, or hazardous. “Solid waste” generally comprises, “garbage,” including decomposable wastes from food; “rubbish” including combustible decomposable wastes, such as paper, wood, and cloth, or non-combustible decomposable wastes, such as metal, glass, and ceramics; “ashes” including the residue of the combustion of solid fuels; “large wastes” including demolition and construction debris and trees; dead animals; “sewage treatment solids” including the material retained on sewage-treatment screens, settled solids, and biom...

Embodiment Construction

[0066] The present invention relates to solid waste disposal and includes apparatuses, systems, and methods for transforming solid waste into useful material.

[0067] Embodiment of the apparatuses of the present invention, which may be combined to create an embodiment of a system for transforming solid waste into useful material, may comprise the following: apparatuses to reduce the particle size of the waste (e.g., hammer mills, grinders, shredders); apparatuses to quickly remove objects which cannot be processed by the particle size reducing apparatuses (e.g., a hinged hopper assembly); apparatuses to remove metal (e.g., magnetic separators); apparatuses to separate components of the waste based on weight or size; apparatuses for transferring preprocessed waste material (e.g., a material injection assembly); apparatuses for decomposing the waste material (e.g., a hydrolyzer); apparatuses for transferring material from a hydrolyzer (e.g., a processed material handling apparatus); an...
