Abstract:
A method and device for converting municipal waste into energy. This method involves heating the waste in multiple sections of a chamber to produce syngas and biochar. The syngas is removed with a vacuum pump and the biochar advances to the next section and is heated to a higher temperature to release more syngas. All of the collected syngas is then transferred to a bio-reactor that removes dangerous carbon monoxide from the syngas mixture by combining the syngas with hydrogen, causing the carbon monoxide to react with the hydrogen and produce methane and water. The resulting syngas can then be used for electricity production or stored as dimethyl ether.
Abstract:
Provided is a sampling method of recycled raw material, the method including: a process (S3) of primarily crushing recycled raw material; a process (S4 to S7) of separating primarily crushed raw material into three components, “scrap iron”, “scrap aluminum”, and “recycled raw material component other than scrap iron and scrap aluminum” and performing primary sample reductions of the three components; a process (S8 to S10) of secondarily crushing “the recycled raw material component other than scrap iron and scrap aluminum”, which is subjected to the primary sample reduction, and performing a secondary sample reduction of “recycled raw material component other than scrap iron and scrap aluminum” which is secondarily crushed; and a mixing process (S12) of mixing “scrap iron” and “scrap aluminum” with “the recycled raw material component other than scrap iron and scrap aluminum” which is subjected to the secondary sample reduction.
Abstract:
An object of the present invention is to provide a method for recovering a rare earth element from a workpiece containing at least a rare earth element and an iron group element, which can be put into practical use as a low-cost, simple recycling system. The method of the present invention as a means for resolution is characterized by including at least a step of separating a rare earth element in the form of an oxide from an iron group element by subjecting a workpiece to an oxidation treatment, then turning the treatment environment into an environment where carbon is present, and subjecting the oxidation-treated workpiece to a heat treatment at a temperature of 1150° C. or more.
Abstract:
A method for disposing of solid refinery waste is disclosed. The method includes removing solid waste constituents from inside a refinery tank using excavating machinery, delumping the solid waste constituents, and conveying the delumped solid waste constituents into a mobile tank. The method further includes transporting the delumped solid waste constituents in the mobile tank to a burning facility, adding at least one diluent, mixing, and pumping from the mobile tank a flowable mixture of refinery waste and the at least one diluent at the burning facility.
Abstract:
Without limitation, the disclosure provides processes for (a) dissolving biomass in ionic liquids, (b) deconstructing cellulose, hemicellulose and/or lignin into derivatives including fermentable sugars, (c) separating the biomass derivatives from the ionic liquid, and (d) converting the biomass derivatives to useful fuels or chemicals, either dissolved within or separated from the ionic liquid. It should be understood that processes described herein can be used in isolation or in combination with each other.
Abstract:
A water absorbing material contains paper powder obtained by separating gypsum from a gypsum board as its raw material. The weight ratio of the gypsum adhering to the paper powder with respect to the paper powder is 5% or less.
Abstract:
The present invention aims to provide recycled fibers having a low dirt content and excellent appearance and strength properties derived from sanitary products. Recycled fibers having a superabsorbent polymer (SAP) content of less than 10% obtained by subjecting a sanitary product containing a cellulose pulp to a recycling process per se have good appearance, and moldings prepared by using the recycled fibers also have excellent appearance and strength properties. Further, the recycled fibers preferably have a dirt area fraction of 50,000 mm2/m2 or less when determined by a staining assay using cobalt (II) chloride hexahydrate, and a Canadian standard freeness of 600 ml or more.

Abstract:
A separation device includes a first shredding unit, a first separation unit, and a first ridge. The first shredding unit shreds a processing target containing a first material and a second material. The first separation unit rotates a first tubular portion in a state in which the processing target shredded by the first shredding unit is accommodated therein, thereby separating the second material passing through first holes from the processing target. The first ridge is provided on an inner circumferential surface of the first tubular portion, and extends in a direction in which the central axis of the first tubular portion extends.
Abstract:
A device for removing a set of springs from a mattress box spring including a mattress box spring support, a pushing block support frame secured to the mattress box spring support, a pushing block supported by the pushing block support frame adjacent to the mattress box spring support, a cylinder for extending the pushing block over a mattress box spring positioned on the mattress box spring support belt, wherein the cylinder is operable to extend the pushing block transversely over the mattress box spring to separate springs attached to a frame of the mattress box spring from the frame, and wherein a plurality of forks extend in front of the pushing block transversely to the mattress box spring support for helping to prevent the springs from folding underneath a bottom of the pushing block when the pushing block is extended over the mattress box spring to separate the springs from the frame.
Abstract:
A burning-free and non-cyanide method for recycling waste printed circuit board is provided, comprising the following steps: desoldering to separate lead and tin; crashing and electrostatic selecting to respectively extract stibium, aluminum, copper, nickel, silver, gold, platinum and palladium. The method can realize the maximization of recycling of valuable metal resources, can thoroughly separate the metal lead and tin for recycling, and meanwhile increase the recycling rate of the metal palladium.
