Sometimes, a problem is obvious, everyone sees it, but nothing happens until someone decides to do something useful about it. Methods are herein provided for recovering heavy hydrocarbons from plastic materials and/or geo-formation. In one solution set, PVC waste materials are emulsified by an amine solvent in an aqueous phase, thereby extracting heavier hydrocarbons from the primary structure of PVC into the amine aqueous phase; followed by de-emulsifying the extracted heavier hydrocarbons by separating and recovering the amine solvent, and then separating the de-emulsified heavier hydrocarbons from the aqueous phase by a hydrophobic membrane.

The present invention concerns a method for the selection and separation of polymers originating from urban and/or industrial plastic waste to obtain plastic materials for recycling which comprises a first step of supplying a mixture of polymers composed of flakes of polymers having dimensions ranging from 6 to 100 mm; a step of identification by means of near-infrared (NIR) spectroscopy of the flakes of coloured and white plastic material and the flakes of black plastic material and subsequent separation from one other; several consecutive steps of identification by means of NIR spectroscopy of the different types of polymer from the coloured and white plastic material and subsequent separation of said polymer types.

A carbon fiber recycling method utilizes a carbon fiber recycling device for recycling carbon fiber from a carbon fiber polymer composite by using a microwave. The carbon fiber recycling device has a cavity and at least one microwave supplying unit. The carbon fiber recycling method adjusts the microwave supplying unit to change the angle between the long axis direction of the cavity and the electric field direction, and to make the long axis direction of the carbon fiber parallel to the electric field direction. By radiating the microwave on the carbon fiber polymer composite, energy of the microwave is quickly absorbed by the carbon fiber to quickly increase a temperature of the carbon fiber, and the carbon fiber polymer composite is effectively and quickly decomposed to remove most polymer matrix of the carbon fiber polymer composite, so as to achieve the objective of recycling the carbon fiber indeed.

Chemical recycling facilities for processing mixed plastic waste 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 generation/energy production 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.

Quantities of plastic solids derived from mixed plastic waste are provided. The quantities can comprise polyolefins and/or polyethylene terephthalate and can be co-located with other quantities of plastic solids. The quantities of solids plastics can comprise particulate plastic solids that are suitable for use as feedstocks to various chemical recycling processes.

The embodiments discussed herein are related to a steam peeling device for an automobile tinting film comprising: a steam tarpaulin in the form of a rectangular oval; a wire frame sleeve seam part in which an outer seam part of the steam tarpaulin is rolled, folded and sewn at regular intervals; and a steam jack formed by fusion on one side of the middle of the steam tarpaulin; and a steam peeling device body in which a wire frame band having a certain length is inserted into the wire frame sleeve seam part, and a banding adjusting pinial formed at the end thereof are cross-pulled out to the upper edge slit in the middle part of the welding end of the steam tarpaulin wire frame sleeve seam part, the improvement of which includes: a wire frame banding module that is rivet assembled on both surfaces of the steam tarpaulin in contact with a slit in the middle part of the upper side border of the wire frame sleeve seam part, a wire frame sleeve stainless pipe in which a banding hole is cut and formed in the middle; a wire frame banding top plate having a length and a constant width standard of the wire frame sleeve stainless pipe, which is assembled in the front part of the steam tarpaulin of a portion where both ends of the wire frame band 4 intersect and protrude on both sides of the banding hole of the wire frame sleeve stainless pipe via the inside of the wire frame sleeve seam part; a pair of tapered slit fitting members that is integrally protruded and formed at the standard intervals of the banding holes on both sides of the upper border of the wire frame banding top plate; a U-shaped groove that is formed in a back face border of the upper side end of the tapered slit fitting member and a back face border on the lower side of the wire frame slit top plate; a pair of gripping parts that are formed to protrude at a predetermined interval to the right and left in the middle part of the front face of the wire frame banding top plate; a wire frame fixing groove that is formed in the vicinity of the wire frame banding top plate inside the pair of gripping parts; a cover plate which is a rectangular member having a standard corresponding to the back face part of the wire frame banding top plate; and a plurality of rivet holes that are penetrated opposite to each other in the wire frame banding top plate and the cover plate. The steam peeling device of the present invention solves the problem of the conventional case that the wire frame banding is loosened during the steam peeling operation, the steam tarpaulin is separated, or a part of the steam is released, and thereby solves the trouble of resetting the wire frame banding during operation, thereby l
