A method for preparing cellulose dope from textile waste including cellulose fibers in a mass percentage of more than 50%. The method includes shredding the textile waste in order to obtain a first mixture of shredded fibers and residues, separating at least a portion of the non-cellulosic components from the first mixture in order to obtain a second mixture in which the mass percentage of cellulose fibers is greater than the mass percentage of cellulose fibers in the first mixture, filtering the second mixture in order to recover a solid phase including the cellulose fibers, dissolving the cellulose fibers of the solid phase so as to obtain a cellulose dope including undissolved particles, and filtering the cellulose dope in order to obtain a cellulose dope that is separated from the undissolved particles.

The present description relates to press extractors for processing municipal solid waste or source separated organics, and can have large perforations for separation of a wet fraction from a liquid depleted fraction. The extractor can also be operated based on a target plug thickness of the liquid-depleted plug left over in the perforated chamber after compression. The extractors can facilitate good organics extraction yields, and lower operating pressures, among other benefits.

The present disclosure refers to a method of electrochemical conversion of organic waste to organic acid and hydrogen, comprising the steps of: (i) subjecting organic waste to ball milling under alkaline or acidic conditions to obtain pre-treated organic waste; (ii) introducing the pre-treated organic waste to a first compartment of an electrochemical cell, wherein the electrochemical cell comprises: the first compartment containing a nickel-based anode, a second compartment containing a cathode, and an electrolyte; and (iii) applying an electrical potential between the anode and the cathode, thereby producing organic acid at the anode, and hydrogen at the cathode. The present disclosure also refers to an organic acid or hydrogen produced from the method disclosed herein.

The current invention relates to a system for disassembling garments that are at least partially assembled with heat sensitive yarn, glues and/or heat-demountable rivets. The system comprises at least one heating chamber in connection with means for providing heated air of a temperature of 100 C. or more or superheated steam to the heating chamber. Said heating chamber having at least one opening through which clothing can enter said heating chamber wherein said system further comprises a rotating drum section, wherein said drum section is located within said heating chamber or configured to be moved in and out said heating chamber. A method of using the system is also disclosed. The system and method provide an energy efficient, non-destructive means by which textile elements of garments can be recovered for further use.

The present invention relates to an apparatus (1) for use in cellulose hydrolysis. The apparatus (1) comprises a channel (10) for guiding a stream of cellulose-containing waste in a flow direction (FD); one or more cylinder(s) (20) arranged to rotate around an axis (A), such that, when rotated, one or more side surfaces (21) of said cylinder(s) (20) exhibit a linear velocity vector orthogonal to said axis (A); and one or more complementary surfaces that face said side surfaces (21), such that, when the cylinder(s) (20) are rotated, the side surfaces (21) and complementary surfaces cooperate in grinding the waste. The present invention further proposes a respective method for cellulose hydrolysis.

The present invention provides a system for thermal remediation and/or the processing of a feed materials like contaminated materials, waste polymeric materials, waste paper products, waste wood and biomass. The system comprises at least one thermal screw conveyor provided in a housing under pressure, a first plug screw conveyor in a housing in communication with an inlet of thermal screw conveyor housing and a second plug screw conveyor in a housing in communication with an outlet of thermal screw conveyor housing. The thermal housing is configured to heat the feed material to form one or more vaporized products and a solid residue, wherein one or more vaporized products are removed through the one or more vapor ports provided in the pressure housing, and the solid residue is discharged from an outlet of the second seal-housing.

The present invention relates to an apparatus for manufacturing recycled carbon fibers and, more specifically, to an apparatus for manufacturing recycled carbon fibers using induction heat generation by high-frequency electromagnetic radiation of carbon fibers in carbon fiber mixed waste, and a method for manufacturing recycled carbon fibers using the same.

A new method for storing CO.sub.2 in the form of naturally bound carbon over a long period of time. More specifically, a method for storing organic material in bogs to reduce CO.sub.2 in the atmosphere. The method, includes the steps of providing organic material, mixing the organic material with water to form a pumpable slurry, pumping the slurry into a bog through one or more pipes, monitoring the bog and taking measures if required to maintain its conservation capabilities.

The present invention relates to a method for digesting biodegradable packaging waste and an apparatus thereof. Specifically, the present invention relates to a method of treating biodegradable packaging waste prior to subjecting the biodegradable packaging waste to a biological valorisation process and an apparatus thereof. The apparatus includes a tank for receiving the biodegradable packaging waste therein, the tank comprises a top portion and a bottom portion below the top portion, an air supply module adapted to supply air into the tank, a microbe injector adapted to inject mesophilic microbe into the tank, such that the tank is adapted to receive the biodegradable packaging waste, air and mesophilic microbe therein, wherein the biodegradable packaging waste is subjected to mesophilic aerobic digestion prior to conveying the biodegradable packaging waste from the tank to a biological valorisation system to subject the biodegradable packaging waste to the biological valorisation process.

A method and system for composting shoes allows shoes to be degraded alongside the composting of compostable material during operation of a single composting vessel. The system includes one or more containers that separate the shoes from the compostable material during operation of the composting vessel. The shoes are subject to multiple runs of the composting vessel. During each run of the composting vessel a new batch of compostable material is composted alongside the shoes.
