Described herein are methods of recycling polypropylene based personal protective equipment. The method may comprise the steps of: (a) conveying a feed of personal protective equipment; (b) cleaning at least a portion of the feed of personal protective equipment; (c) fragmenting the personal protective equipment into a plurality of fragments, the plurality of fragments comprising non-polypropylene fragments and polypropylene fragments; (d) separating at least a portion of the non-polypropylene fragments from the polypropylene fragments to produce a batch of polypropylene fragments; and (e) pelletizing the batch of polypropylene fragments to produce polypropylene pellets.

Methods of sequestering toxin particulates are described herein. In a primary processing chamber, a carbon source of toxin particulates may be combined with plasma from three plasma torches to form a first fluid mixture and vitrified toxin residue. Each torch may have a working gas including oxygen gas, water vapor, and carbon dioxide gas. The vitrified toxin residue is removed. The first fluid mixture may be cooled in a first heat exchange device to form a second fluid mixture. The second fluid mixture may contact a wet scrubber. The final product from the wet scrubber may be used as a fuel product.

Methods of making a fuel fluid are disclosed. A first working fluid and a second working fluid may be provided. The first working fluid may be exposed to a first high voltage electric field to produce a first fluid plasma, and the second working fluid may be exposed to a second high voltage electric field to produce a second fluid plasma. The first fluid plasma and the second fluid plasma may be contacted to form a fluid plasma mixture, which is transported to a heat exchange device. The fluid plasma mixture may be cooled to form a fuel fluid; and the fuel fluid may be collected.

A method for treatment of ash from incineration plants includes: collecting ash from an incinerator; feeding the collected ash and additional feed material to a gasification/vitrification reactor; vitrifying the ash and additional feed material in the gasification/vitrification reactor, to form a slag of molten material; allowing the slag to flow from the gasification/vitrification reactor and solidify outside the gasification/vitrification reactor; gasifying volatile components in the ash and the additional feed material; combusting syngas generated in the gasification/vitrification reactor in a secondary combustion zone in the gasification/vitrification reactor; and supplying products of the syngas combustion to the incinerator to augment the thermal environments of the incinerator. An apparatus used to practice the method is also provided.

A production method of carbon dioxide fixing sludge fine powder as a low-carbon binder. Water is added to residual concrete or returned concrete to form it into a slurry, gravel and sand are separated and removed therefrom, fine sand is separated and removed from the sludge water by a wet cyclone to obtain concentrated sludge water, and the concentrated sludge water is dehydrated to obtain a sludge cake. The sludge cake is put into a rotary drum, hot air and highly concentrated carbon dioxide are supplied into the rotary drum, the carbon dioxide is fixed and is crushed and dried to obtain carbon dioxide fixing sludge fine powder. Alternatively, the sludge cake is crushed and fractured to obtain sludge fine powder. This sludge fine powder is exposed to highly concentrated carbon dioxide to obtain carbon dioxide fixing sludge fine powder.

The present invention relates to a composite material, particularly a composite material for ceramic tiles, stone cladding, surface tops (e.g. worktops), and the like. The composite materials are typically derived from waste products. The composite materials of the present invention are formed from a glass component and a non-glass mineral component (e.g. ceramics and/or glaze). Generally the composite materials do not require any binders (especially synthetic binders) to hold the materials together. Therefore, the composite materials and products made therefrom are typically recyclable.

A method of and an arrangement for recycling mineral wool waste to mineral wool production includes at least one melting furnace for melting virgin mineral wool raw material, the melting furnace including an inlet for virgin mineral wool raw material and an outlet for molten mineral wool material, a production line connected to the outlet for molten mineral wool material for producing a mineral wool product from the molten mineral wool material. The production line includes a curing oven, a fluidized bed reactor including an exhaust gas duct, an inlet for predetermined primary fuel, an inlet for predetermined bed material, and an outlet for an ash material, the ash material including bottom ash discharged via a bottom outlet from the fluidized bed reactor or fly ash separated by a particle separator from exhaust gas in the exhaust gas duct or a mixture of the bottom ash and the fly ash.

In a first processing chamber, a feedstock may be combined with plasma from, for example, three plasma torches to form a first fluid mixture. Each torch may have a working gas including water vapor, oxygen, and carbon dioxide. The first fluid mixture may be cooled and may contact a first heat exchange device. The output fluid from the first heat exchange device may be separated into one or more components. A syngas may be derived from the one or more components and have a ratio of carbon monoxide to hydrogen of about 1:2. The syngas may be transferred to a catalyst bed to be converted into one or more fluid fuels.

Disclosed herein are systems and methods for a waste processing system. The system comprises a container preparation area wherein containers are prepared for in-container vitrification processes, a feed area where spent media, recycled waste, and one or more of glass frit, silica sand, or glass formers, are blended to form blended waste. The blended waste is metered into a prepared container from the container preparation area as electricity is applied to electrodes placed in the waste within the container, thereby creating heat sufficient to melt the contents of the container. This results in a container containing vitrified glass product with entrained contaminants. The system includes a container cooling area where the processed container may be cooled, and a container disposition area where the processed container may be surveyed, decontaminated, sealed, shielded, and/or prepared for storage.
