A sealing system for isolating the environment inside a vitrification container from the outside environment comprises a vitrification container with a lid. The lid comprises two or more electrode seal assemblies through which two or more electrodes may be operatively positioned and extend down through the lid into the vitrification container. The electrodes may move axially up and down through the electrode seal assemblies or lock into place. The electrode seal assemblies each comprise a housing having two halves with recessed ring grooves. Sealing rings with a split may be placed into the grooves. Gas galleries may be machined or cast into the housing such that they are adjacent to the ring grooves. The gas galleries distribute gas onto the external faces of the sealing rings causing a change in pressure resulting in the sealing rings compressing onto the electrodes and forming a seal.

A recycling and fabrication appliance is provided. The recycling and fabrication appliance is generally configured to convert solid waste, solid materials and/or solid objects into a usable or reusable product. The recycling and fabrication appliance generally comprises a single unit with one or more inputs and one or more outputs. The unit may be a cuboid, or may be any appropriate shape, and may specifically be configured to recycle or repurpose solid waste, solid materials or solid objects into a reusable form at or near the point of consumption or disposal, such as a household or office. The components of the recycling and fabrication appliance may be housed within the unit and may enable the recycling and fabrication appliance to receive various solid waste pieces as an input and to produce a single usable output, referred to herein as a output object.

A canister for interim storage and subsequent consolidation of waste materials via hot pressing and comprising at least one ion exchange material. The canister is configured to house the ion exchange material after it is exchanged with a contaminating ion without releasing the contaminating ion and to consolidate waste materials via hot-isostatic pressing. A method comprising contacting a fluid waste with an ion exchange material.

An apparatus for forming a plastic article is disclosed, comprising at least one intake conveyor to receive a plurality of plastic material and transfer the plurality of plastic material to at least one shredder to shred the plurality of plastic material. At least one stage conveyor transfers plastic from the at least one shredder to at least one load conveyor to transfer shredded plastic to at least one weigh apparatus. At least one boiler system provides pressure and heat to at least one blocker cell to process the shredded plastic to a block or similar article. At least one offtake conveyor receives and expels the block.

A system for and method of, processing post-consumer and post-industrial waste streams, producing active ingredients for waste stream processing, processing aqueous waste streams, preparing and collecting a multi-purpose chemical precursor, removing phosphates, nitrates, heavy metals, and other contaminants from aqueous waste streams, collecting and processing a post-consumer and post-industrial product from aqueous waste streams, administering and positioning assets and processes associated with waste stream processing, and scheduling operations for sub-systems of the system.

The present invention provides systems, methods and devices for storing and/or disposing of hazardous waste material such as calcined material. In certain embodiments, the system comprises a filling nozzle having a valve body having a distal end and an outer surface, the outer surface proximate the distal end being configured to sealingly and removeably couple to an inner surface of a filling port of the container. In certain embodiments, the method comprises (a) coupling an outer surface of a filling nozzle with an inner surface of a filling port of a container to form a first seal (b) adding hazardous waste material into the container (c) decoupling the filling port from the filling nozzle and (d) inserting a fill plug into the filling port, the fill plug forming a second seal with the inner surface of the filling port, the second seal being distally spaced from at least a portion of the first seal with respect to the container.

An underground ventilated system for storing nuclear waste materials. The system includes a storage module having an outer shell defining an internal cavity and an inner shell. A majority of the height of the outer shell may be disposed below grade. The outer shell may include a hermetically sealed bottom. First and second canisters are positioned in lower and upper portions within the cavity respectively in vertically stacked relationship. A centering and spacing ring assembly is interspersed between the first and second canisters to transfer the weight of the upper second canister to the lower first canister. The assembly may include centering lugs which laterally restrain the first and second canisters in case of a seismic event. A natural convection driven ventilated air system cools the canisters to remove residual decay heat to the atmosphere. In one non-limiting embodiment, the shells are made of steel.
