This invention provides a system or method that includes combustion of mixed content solid waste to produce flue gases and separation of carbon dioxide gas in the produced combustion flue gas from other gaseous constituents of the flue gas in an amount produced from the burning of plastic material contained in the mixed content solid waste. The separated carbon dioxide is sequestered in geologic formations, thereby providing environmentally sound disposal and elimination of plastic waste, in one consolidated process, free of the need for separation of plastic waste from other solid or the need to identify and separate the various forms and compositions of plastic waste material. The illustrative disposal of plastic waste hereby is generally free of emission into the atmosphere of carbon dioxide gas. The invention includes a fee-generation process applied to customers, which can quantified and generated in association with the application of the system or method.

The embodiments described relate to an expeditionary solid waste disposal system configured to improve logistics and enable it to be readily deployed. The two-stage gasification/oxidation process takes place in a dual chambered device that resembles and functions as a shipping container. Incinerators or other waste conversion devices are commonly containerized by loading the equipment into a standard or modified shipping container. This apparatus is designed as a waste conversion unit that integrates all of the necessary features required to be an ISO-certified shipping container within its structural design such that the waste conversion system and shipping container are one and the same. With correct set-up by 2 persons aided by forklift the system can be configured and operational in a matter of hours.

A power-generation system having a combined heat and power plant and a fermentation plant has an electrolysis plant, which is connected by lines to both the combined heat and power plant and to the fermentation plant. This arrangement enables a method in which heat from a combined heat and power plant can be used for a fermentation plant and additionally heat from an electrolysis plant can be used for the fermentation plant, whilst the oxygen from the electrolysis plant is used for the combined heat and power plant.

A nonflammable burner includes a can with holes in its sidewalls and bottom. Hollow legs are coupled to the bottom of the can. Each hollow leg has an open end in fluid communication with an interior of the can with perforations in each hollow leg providing fluid communication with an interior of the hollow leg such that each hollow leg provides fluid communication between an ambient environment and the interior of the can. A tray is positioned on a ground surface and engages with the hollow legs wherein the bottom of the can is spaced apart from the tray. Open-ended conduits extend between the sidewalls of the can to provide a fluid flow path there through. Each conduit admits the ambient environment therein, and includes perforations for providing fluid communication between the fluid flow path and the interior of the can.

Example embodiments of the present invention relate generally to medical waste management and more specifically to a method and apparatus for carbonization of waste material using convective heat from the metallic inner surface of a waste treatment chamber and superheated nitrogen gas.

The invention relates to an apparatus which comprises a pyrolytic plasma reactor (1) with: a conical head (8), on which are mounted: inlets (2, 3, 4); a first plasma torch (6); and first gas outlet (5); a cylindrical reaction chamber (9), under the head (8), and which comprises: a side wall (11) with a refractory covering (12); and a bottom (16), o with a decreasing cross-section, for receiving lavas; a base (10), for supporting the head (8) and the reaction chamber (9); and discharge means in the reaction chamber (9) and/or in the base (10) for discharging the lavas. By keeping the first torch (6) lit, the method comprises directing solid, liquid and gaseous hazardous waste towards the central portion of the plasma jet from the first torch (6), with no contact between the various types of hazardous waste. The dissociation conditions are improved by the invention.

A rotary cascading bed combustion system for converting waste product into energy includes a rotary cascading bed combustor boiler including a rotating cylinder surrounding a combustion chamber; the rotating cylinder being structured and disposed for cascading the fuel to facilitate the mixing of air and solids, wherein the rotational speed of the rotating cylinder is selectively varied based on the amount of fuel, airflow and combustion properties; wherein combusting waste is mixed with sorbents and cycled through a plurality of combustion zones to produce controlled heat for generating steam; wherein the steam is routed to a turbine; and wherein if carbon burnout is not complete it will be recycled back into the combustion chamber.

An aspect of the present disclosure relates to a thermite bag, which may be used for the disposal of hazardous material. The thermite bag includes a sealable exterior pouch, a sealable interior pouch receivable within the exterior pouch, a thermite charge receivable within the sealable interior pouch and an igniter wire contacting thermite within the thermite charge. The thermite bag also includes a power supply electrically coupled to the ignitor wire and a trigger electrically coupled to the ignitor wire and power supply. In addition, the thermite bag includes a vent including a filter, wherein the vent is coupled to the sealable exterior pouch.

Materials recycling processes that include a combustion stage can operate very efficiently, but can produce exhaust gases that are high in carbon monoxide and the like. We describe a treatment unit which comprises a chamber for receiving the material, a heat source for (preferably) heat-treating the material and for initiating combustion, and a gas outlet from the chamber, which allows the gas that is exhausted via the outlet to be supplied to the air inlet of an associated boiler unit, with the air inlet and a separate fuel inlet feeding a burner for combusting fuel from the fuel inlet in air from the air inlet in order to heat a transfer fluid. In this way, the unburnt elements of the gas expelled from the chamber are included in the combustion process of the boiler unit and fully combusted. A corresponding method is also disclosed.
