Some embodiments are directed to a process for the treatment of organic waste which couples in situ biostimulation to produce hydrolytic enzymes and hydrolysis of the refractory organic matter from waste using these enzymes with a view to energy recovery.

A method for separating different types of material layers of a composite component that has at least one material layer that is transparent for visible light and at least one further material layer, is provided, wherein the light from an external source falls through the at least one transparent material layer into the at least one further material layer and there is at least partially absorbed. With the help of at least one gas discharge lamp, the light-absorbing material layer is heated in less than one second to separate material layers of the composite component. A device that can be used for this method comprises at least one separation chamber and therein at least one gas discharge lamp suitable for irradiation.

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.

Biocarbon is presented as an alternative to synthetic carbon black. Master batches having biocarbon for usage in raw plastics and/or the production of composites. Biocarbon is mainly derived from plant biomass, but other sources can be used. A method of producing the master batch: (a) pyrolyzing processed biomass in an oxygen-starved environment to produced biocarbon; (b) comminuting the biocarbon in a reduced oxygen atmosphere; (c) cooling the comminuted biocarbon; (d) mixing the cooled comminuted biocarbon with a carrier resin, thereby producing the master batch.

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.

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.
