An apparatus is provided that receives waste and generates electrical power or thermal energy with minimal NOx emissions. A gasifier is provided that receives the waste and air to produce fuel gas for delivery to a fluidly coupled reformer. The reformer receives the fuel gas, recycled flue gas, and air to auto-thermally produce a reformed fuel gas and destroy fuel gas pollutants at a first temperature without a catalyst. A burner is fluidly coupled to the reformer and receives recycled flue gas and air to oxidize the reformed fuel gas at a second temperature that prevents nitrogen oxide formation, the second temperature being lower than the first temperature. A quench chamber is fluidly coupled to the burner and receives flue gas from the burner for quenching with recycled flue gas. A heat recovery system is fluidly coupled to the reformer, burner, and quench chamber to extract usable energy.

Provided is a method for efficiently recovering pulp fibers with a high degree of safety and without detriment to the performance of the pulp fibers, from used absorbent articles such as disposable diapers containing pulp fibers and a super absorbent polymer. This method comprises: a step for extracting a mixture of pulp fibers, super absorbent polymer and water from used absorbent articles; a step of using a pair of electrodes to apply a voltage to the mixture of pulp fibers, super absorbent polymer and water to deactivate the super absorbent polymer; and a step for separating pulp fibers from the mixture of pulp fibers, deactivated super polymer and water.

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.

The present invention relates generally to the field of waste processing. The method comprises separating waste into at least two parts, comprising: (i) mainly food waste (fines) and (ii) mainly paper and other recyclable material (overs). The overs are pulped and washed to obtain a cellulose-rich biomass and the fines are optionally processed separately to recover a cellulose-rich biomass and the cellulose-rich biomass from both the fines and the overs may be combined.

Clean, safe, and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various waste sources into a Clean Fuel Gas, Char, and Biochar are provided. The process further converts the Clean Fuel Gas into both a purified hydrogen source for green ammonia production and natural gas. The methods process waste sources to effectively separate, neutralize and/or destroy halogens and other hazardous components to provide a Clean Fuel Gas, Char and/or Biochar, which can then further be processed to extract and purify hydrogen for green ammonia production from the Clean Fuel Gas and thereby provide natural gas. The Clean Fuel Gas is a natural and renewable natural gas as it is continually produced and further available for use to provide energy and new products.

A recycling apparatus is composed of a high-pressure water generating device, generating high-pressure water, and a jet nozzle that is connected to the high-pressure water generating device and spouts the high-pressure water toward a solar panel. The jet nozzle spouts the high-pressure water toward a back surface of the solar panel to remove a layer of the solar panel until a cover glass included in the solar panel.

A method of recycling a solar cell module includes an enclosing layer that encloses a solar cell therein, a light-receiving surface layer laminated on one surface of the enclosing layer, and a back sheet laminated on the other surface of the enclosing layer, the method including: a first removing step of mechanically removing the back sheet; a second removing step of mechanically removing from a side on which the back sheet is removed the entire solar cell and the enclosing layer to such a depth that a part of the enclosing layer having a predetermined thickness remains on the light-receiving surface layer, after the first removing step; and a third removing step of removing the part of the enclosing layer remaining on the light-receiving surface layer by immersion in a solution that causes swelling of the enclosing layer, after the second removing step, thereby improving an overall efficiency.

A process for treating waste from a pithead power plant and sequestrating carbon dioxide discharged therefrom is provided. A mixed material of solid waste from the power plant, cement and a mixing liquid is filled into a depleted coal mine and compacted. A hydrating liquid is then injected into the filler after compaction to cause hydration. After that, carbon dioxide discharged from the power plant is injected to mineralize the carbon dioxide, thereby achieving carbon dioxide sequestration and reinforcement of the depleted coal mine. The invention utilizes abundant basic oxides present in the solid waste, and the fact that calcium hydroxide and tobermorite present in the hydrated cement chemically react with the injected carbon dioxide to produce stable carbonates in solid, and thus simultaneously achieves carbon dioxide sequestration, treatment of solid waste, and reinforcement of a depleted coal mine.

The invention relates to a method and system for obtaining a liquid fuel from waste from plastic or polymer material, which, according to its structure of steps and devices, allows lower energy use with respect to the disclosure in the prior art. In addition, by means of the method and system, the load of plastic and polymer waste in the environment, mainly waste that may be destined for landfill, is reduced. Thus, in addition to waste material being reduced, energy is recovered at highly favourable cost, as a result of the layout of electric heating elements for delivering the energy or heat needed to correctly transform the waste material, in short processing periods and with the adaptability of being able to be formed from moveable, transportable systems, even large industrial installations.

The present invention provides a solar panel recycling system includes: a frame dismantling machine for disassembling the outer frame of a solar panel; a crushing machine for placing the solar panel without the outer frame on the conveyor belt of the crushing machine, wherein the crushing machine includes a sensing unit for sensing the thickness of the glass on the solar panel; and a control unit for controlling the speed of the conveyor belt based on the thickness of the glass and simultaneously controlling the crushing unit to crush the glass on the solar panel, so as to achieve the effect of the separation between the glass and the solar cell module.
