The present invention provides an apparatus for recycling composite material and a method for recycling composite material by using same, the apparatus including: a mixing tank in which pulverized products of fiber-reinforced waste plastic are dispersed and mixed in water together with a filler, thereby forming a composite material mixture; a fixing agent addition part for forming a recyclable material by supplying, to the composite material mixture, a fixing agent that aggregates the pulverized products of the fiber-reinforced waste plastic and the filler; and a filtering tank in which the recyclable material is supplied such that a recyclable composite sheet is formed.

Embodiments of the present invention may provide methods and systems for recycling asphalt shingles (1) perhaps in a chemical solution (2) to provide oil free recyclable fiberglass (6), oil free recyclable sand (7), and even recyclable oil (8). The present invention may provide a screened tubular rotating equipment (16) may be at least partially immersed (18) in a tank (17) of a chemical solution (2) to treat the asphalt shingles (1).

The invention relates to a process and an installation to produce a monovinylaromatic polymer (3) comprising post-consumer recycled polystyrene (PCR-PS) wherein the process comprises the steps of mixing the PCR-PS (5) and the monovinylaromatic monomer (7) within a dissolver (9) to dissolve the PCR-PS (5) in the monovinylaromatic monomer (7) so as to produce a polymerization mixture (13); and a step of filtering the polymerization mixture (13) that includes continuously redirecting at least a part of the stream of the filtered polymerization mixture (17) back to the dissolver (9) and mixing it with the polymerization mixture (13) so as to continuously reduce the content of insoluble material in the polymerization mixture (13) contained in the dissolver (9).

A method for recycling of packaging material is disclosed. The packaging material comprises a multilayer material (10) comprising a metal layer (30) and at least one polymer layer (20, 40). The method comprises placing the packaging material in a vat (310) comprising a separation fluid (330) to produce a mixture of metal shreds from the metal layer (30), plastic shreds from the polymer layer (20, 40) and residual components. The separation fluid comprises a mixture comprising a mixture of water, a short-chained carboxylic acid, phosphoric acid and an alkali metal hydroxide solution.

The present disclosure provides a process. In an embodiment, the process includes providing pellets of a regrind material. The regrind material is a post-consumer recycle multilayer film (PCR multilayer film) having at least three layers. The PCR multilayer film is composed of (i) a polyethylene layer, (ii) a polyamide layer, and (iii) a tie layer. The tie layer is composed of maleic anhydride grafted substantially linear ethylene polymer (MAH-g-SLEP) having a Mw/Mn from 1.5 to less than 3.5 and a melt index from 0.5 g/10 min to less than 25 g/10 min. The process includes extruding the pellets to form an extrudate, molding the extrudate, and forming, with the extrudate, a molded article having a surface. The surface of the molded article has a surface roughness value, Sa, less than 1000 nm and a root mean square roughness value, Sq, less than 1400 nm.

Method for production of articles and semi-finished products made of cellulose acetate, comprising the steps of recover-mg waste material consisting of cellulose acetate derived from previously made cellulose acetate articles and/or semi-finished products, distributing or positioning a mixture of at least one polymeric material inside a mould, heating and pressing the mixture inside the mould in order to form the articles or semi-finished products. The mixture is formed at least partially by the waste material consisting of cellulose acetate and the articles and/or semi-finished products may be subjected to a cooling and pressing step. The mixture is formed at least partially by fragments of cellulose acetate.

A waste treatment device for separating recyclable material from other waste comprising: —a first substantially cylindrical cavity inside which the waste to be treated is introduced; —a shaft, rotating about its axis, in the centre of the cylindrical cavity; —screening meshes which separate the cylindrical cavity from a second underlying cavity inside which waste material is collected; —hammers attached at a first end to the shaft so as to be able to rotate in a plane perpendicular to the axis of rotation of the shaft. The hammers are provided with a respective scraper terminating in an edge remaining directed in a direction substantially parallel to the axis of the rotating shaft and projecting longitudinally beyond the end of the hammer so as to pass at a nominal minimum distance from the screening mesh. A related mounting method for a waste treatment device is also disclosed.

An object of the instant application is to provide a process of recycling a bituminous product such as a waste bituminous membrane product optionally containing reinforcement layers comprising grinding and melting steps.

Process for feeding plastic material, e.g. a plastic waste, to a processor such as a thermochemical reactor, e.g. a pyrolysis reactor. The process comprises an optional shredder or disintegrator (1), a conveying system (2), a feed hopper (3) with a lock hopper or rotary valve, a melting tank (6) with an agitator (5) followed by a melt pump (7) for the delivery of molten plastic to the processor. The advantage of the current process includes the ability to supply a consistent, metered flow to the processor, independent of the recycled plastic's melt properties, or the form or particle size and distribution of the plastic material.

A machine and a method for treating cakes from additive manufacturing processes, wherein the cake contains residual powders and sintered pieces is disclosed. The machine includes a cylindrical vibrating body which is placed in a position above a vibratory finishing or tumbling or vibro-blasting machine and is separated from the vibratory finishing or tumbling or vibro-blasting machine by a remotely operable door and the cylindrical vibrating body obtains its vibration from the machine below. The machine includes means for destructuring the cake in order to obtain the separation of the non-sintered powder from the sintered pieces present in the cake and means for recovering the powder resulting from the destructuring of the cake.
