A recycling method is applied to a solar cell module which includes a cover glass, an electric cell layer, and a sealing material which closely adheres the cover glass and the electric cell layer. The recycling method includes heating an interface between the cover glass and the sealing material to a prescribed temperature range; and applying a force from a side surface of the solar cell module to the sealing material with the interface maintained at the prescribed temperature range, to peel off the sealing material and the electric cell layer from the interface thereof.

A waste treatment system 100 for performing a hydrothermal treatment of wastes includes a hydrothermal treatment device 10 for performing the hydrothermal treatment by bringing steam into contact with the wastes, a storage facility 8, 9 for storing a fuel produced from a reactant of the hydrothermal treatment, and a heat recovery steam generator 18 for generating the steam to be supplied to the hydrothermal treatment device 10. The heat recovery steam generator 18 is configured to generate the steam by using a combustion energy generated by combustion of the fuel stored in the storage facility 8, 9.

An automated and controlled system, method and devices perform carbon capture and sequestration, stabilization of alkaline solid wastes, and a phenomenological method for automatically conducting carbonation reaction using the integrated system under specific reaction parameters.

The following describes a reconfigurable set of industrial processing techniques which, when appropriately combined, enable zero-emissions reforming, utilizing a wide range of conventional and unconventional feedstocks. Hydrocarbons, harvested or refuse biomass, as well as assorted byproducts and wastes are reformed through tightly integrated processing. The system is designed to incorporate alternative energy sources such as renewables or nuclear for high-density energy utilization and storage. Central to the processing methodology is a novel molten salt electrochemical reactor designed as a modular system for high-throughput carbochlorination and resource recovery. Such a configuration drastically reduces or eliminates waste while improving efficiency and realizing vast new economic incentives.

Pulp fiber containing little ash is effectively recovered from a used sanitary product containing the pulp fiber and a polymer absorbent. The method according to the present invention comprises: a step for treating the used sanitary product with an ozone-containing gas and thus decomposing and removing at least a portion of the polymer absorbent in the used sanitary product; and a step for stirring the used sanitary product, that has been treated with the ozone-containing gas, in water or an aqueous solution containing an antiseptic and thus decomposing the used sanitary product into constituents. If required, the method may further comprise a step for separating the pulp fiber from the decomposition product obtained by the decomposition step.

A method is provided for thermally processing waste to produce steam and generate energy while minimizing air pollutants in a staged thermal reactor. The method includes gasifying the waste to convert the waste to a fuel gas and a substantially carbon free, inert, granulated, sintered mineral ash and reforming the fuel gas auto-thermally to minimize creation of nitrogen oxide when the fuel gas is combusted. The method further includes burning the reformed fuel gas to minimize creation of nitrogen oxide in a flame region of a fuel gas burner and recirculating cooled flue gas to control oxygen content and temperature during the reforming operation and the burning operation. In one example, reforming the fuel gas converts non-molecular nitrogen species into molecular nitrogen in an auto-thermal non-catalytic reformer unit by decomposition reactions promoted by a prevailing reducing gas atmosphere.

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.
