A press (10) for waste has a chamber that is enclosed in part by a sliding door (20). The door has an extrusion section (22) and an expulsion section (24). The extrusion section encloses the chamber while waste (18) is compressed in the chamber to extrude a wet fraction (32) of the waste. The expulsion section abuts the chamber when a remaining dry fraction (40) of the waste expelled. Preferably, the expulsion section is above the extrusion section. Various details of the door account for leakage of wet fraction waste between the chamber and the door.

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.

The present invention provides systems, apparatuses, and methods for the treatment of containerized waste, such as hazardous, radioactive and/or mixed waste. The apparatuses and methods employ a combination of thermal decomposition and specialized lances.

A dust solidification apparatus that prevents dust from scattering with a simple structure and that can accurately perform solidification of dust. A dust solidification apparatus comprising: an apparatus body; a hopper for storing dust D, the hopper being provided on the apparatus body; a forming member provided within the hopper, the forming member having a forming hole; and a pressurizing rod that is configured to freely advance and withdraw with respect to the forming hole, wherein the pressurizing rod advances into the forming hole to solidify dust loaded therein, thereby obtaining a solidified substance K, and openings of the forming hole are open within the hopper.

An apparatus for processing a waste battery is proposed. The apparatus includes a conveying unit having a conveying belt rotated by a plurality of rotating shafts which are rotated to convey the supplied waste battery in one direction, a pulverizer disposed on a position along a travelling direction of the conveying unit to pulverize the waste battery, a heater disposed on a downstream side of the pulverizer to heat dust formed by the pulverizer, a collector collecting the dust which passes through the pulverizer and the heater, a filter part filtering a pulverized material of the collector, a mixer supplying an additive to the dust discharged from a discharge pipe of the filter part, and a compressor compressing a mixture mixed in the mixer.

A method for treating and disposing of mercury—from mercury-contaminated waste—includes recovering high-purity mercury (e.g., greater than about 99.0 wt. % elemental Hg) from the mercury-contaminated waste. The high-purity mercury is converted to mercuric sulfide (HgS). The mercuric sulfide (HgS) is intermixed with a polymer-based material to form an encapsulated mercury material. The encapsulated mercury material is disposed within a sealed waste container. The sealed waste container is disposed of at a landfill site. Also disclosed is a mercury-including waste product that comprises pellets. The pellets comprise mercuric sulfide within a polymer material.
