A device for wholly treating urban and rural mixed household refuse at low temperature on site is provided. The device includes a vibration sieving and crushing system, a magnetic separator, conveyor belts, a magnetic pulse mineralization reactor and a tail gas purifying device. By using the device, urban and rural mixed household refuse is continuously fed; the mixed household refuse is sieved by the vibrating sieve according to viscosity, weight and size; nonferrous metal is sieved through a magnetic field; and organic substances are conveyed to the magnetic pulse mineralization mixed household refuse treatment device for terminal treatment. So, efficient reduction and harmlessness of the organic substances in the mixed household refuse are realized, and the pollution of organic wastes on the environment is effectively eliminated.

Various embodiments of the present disclosure can include at least one of a method, apparatus and system for the efficient melting of a feedstock to at least one of a molten and vitrified state to be used in a manufacturing system comprised of: a melter to which the feedstock is provided; and a heat recovery system configured to capture exhaust waste heat produced by the melter, wherein the heat recovery system transfers an energy recovered from the exhaust waste heat to pre-heat the feedstock provided to the melter.

Provided herein are composite materials comprising at least 70 wt. % thermally consolidated recovered paper and plastic fragments and less than 5,000 ng water-soluble endotoxin per gram of composite materials, as well as methods of preparing said composite materials and methods of sanitizing recovered waste materials.

An apparatus for hardening waste resin is disclosed herein. The apparatus includes a container for holding the waste resin, the container having an outlet. The apparatus may also have a container pivot about which the container may rotate to a tilt position that allows waste resin to flow out of the outlet under the force of gravity, over a comb with a plurality of teeth. The teeth are constructed to separate the waste resin into waste resin droplets under the force of gravity. A conveyor surface is positioned below the comb to receive the waste resin droplets, and the conveyor surface moves as it receives the waste resin droplets. A plurality of UV lights is positioned to illuminate the conveyor surface and cause the waste resin droplets thereon to harden. The conveyor surface may be removable.

The present invention relates generally to methods for the preparation of nickel-based alloys using waste materials, and more particularly to the preparation of nickel-based alloys using spent batteries.

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.

A method for manufacturing a recyclable article from municipal solid waste (MSW) without addition of binders is disclosed. The method includes aspects of processing, a proportionate quantity of biodegradable waste and non-biodegradable waste to form a mixture. The processed mixture is loaded into a mould placed in a melter (9). The processed mixture is subsequently melted in the melter (9) at a pre-determined temperature and pre-determined pressure, where the non-biodegradable waste circumscribes and form a bond with the biodegradable waste during melting. The melted mixture is compressed in a compression moulding device (10) at a pressure ranging from 0.1 Kg/cm.sup.2 to 3.0 Kg/cm.sup.2. Further, the compression of the melted mixture is carried out under supply of a coolant for solidifying and forming the article.
