Devices facilitating recovery of polymers are disclosed. A crushing device (25) includes a housing (13) into which a paper diaper (D) containing polymers (P) in a water-absorbed state is thrown, and a crushing member (28) that is accommodated in the housing (13) and crushes the paper diaper (D). A moving speed of the crushing member (28) is 0.1 m/s or less.

A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

An irrecoverable-waste feeding and metering apparatus for feeding a waste separator, comprising:—a loading hopper having a mixing compartment and a discharge duct which extends between the mixing compartment and a discharge mouth thereof, for discharging material from the latter;—a central auger and two lateral augers; the central auger extending into the discharge duct and into the mixing compartment and the lateral augers are arranged inside the mixing compartment each on one side of the central auger;—a transfer device having a feed channel which has a loading portion and a feeding portion. The transfer device comprises two transfer augers extending from the loading portion along the feed channel and which each have a first helicoid. The first helicoid of a first transfer auger has a direction opposite to that of the first helicoid of the second transfer auger.

A panel and a method for manufacturing thereof where the panel includes a first layer comprising a first blend of paper fragments and plastic fragments; a second layer comprising a second blend of paper fragments and plastic fragments, wherein the paper fragments and plastic fragments of the second blend are coated with an adhesive; and a third layer comprising the first blend of paper fragments and plastic fragments, wherein the second layer is disposed between the first layer and the third layer, and wherein the first layer, the second layer, and the third layer are combined to form the panel using heat and pressure. In another embodiment, the paper fragments and plastic fragments of the first blend, not the second blend, are coated with an adhesive.

Chemical recycling facilities for processing mixed waste plastic are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy recovery facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

In one embodiment, a method for processing polymeric waste materials into one or more products included: pyrolyzing a solid polymeric waste material, wherein the pyrolyzing includes: heating the solid polymeric waste material in the absence of oxygen to a temperature of 725° F. to 850° F. for a duration of 15 to 90 minutes; and thermochemically converting, in response to the heating step, at least some of the solid polymeric waste material into a first liquid product; separating the first liquid product from residual solids; separating a vapor stream from the vessel; and condensing at least a portion of the vapor stream into a second liquid product.

A pyrolysis method and system are provided that may utilize a recycled plastic feedstock that comprises various types of waste plastics or a feedstock that comprises various types of waste plastics and at least one crude post-industrial liquid waste. The disclosed pyrolysis method and system may be configured to convert various types of waste plastics, including post-customer and post-industrial wastes, and/or crude post-industrial liquid wastes into useful pyrolysis oils.

The inventive biorefinery system and method accepts municipal solid waste, sewage sludges, and/or ag-wastes and processes it through three primary conversion unit operations to produce a variety of value-added products. In a preferred embodiment, the three primary conversion units are gasification, thermal depolymerization or torrefaction/pyrolysis, and biotreatment.

The invention relates to a method for the disposal of a composite material, in particular a composite material contaminated, for example, by radioactivity and containing fluorine impurities. The inventive method for the disposal of a component containing a composite material with a composite matrix and a technical fiber, is characterized in that the component is chemically gasified, wherein the composite material is technically completely decomposed into its basic components, wherein in a first step the composite matrix is dissolved and in a subsequent step the remaining starting materials and intermediate products are thermally decomposed and reacted with added process gases, wherein at least in the subsequent step a reactive gas is supplied and the subsequent step is conducted endothermically.

The reactor system comprises a reactor vessel with at least one inlet and a first and a second outlet, which reactor vessel is configured for depolymerisation of a condensation polymer and which first and second outlet are configured for removal of a first and a second part of a reaction mixture. The reactor system further comprises a heat exchanger downstream of the first outlet. Herein the second outlet is arranged at a lower position of the reactor vessel than the first outlet. The first outlet is configured for removal of the first part being a dispersion and/or solution comprising said condensation polymer and depolymerisation products thereof in a solvent. Said first part is led to the heat exchanger. The second outlet is configured for removal of the second part including agglomerates. The reactor system is used for depolymerisation of a condensation polymer.
