NounSingular plastic Plural uncountable plastic (uncountable)
From Wiktionary under the GNU Free Documentation License. A plastic material is any of a wide range of synthetic or semi-synthetic organic amorphous solids used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance and/or reduce costs. Monomers of plastic are either natural or synthetic organic compounds. The word plastic is derived from the Greek πλαστικός (plastikos) meaning capable of being shaped or molded, from πλαστός (plastos) meaning molded. It refers to their malleability, or plasticity during manufacture, that allows them to be cast, pressed, or extruded into a variety of shapes—such as films, fibers, plates, tubes, bottles, boxes, and much more. The common word plastic should not be confused with the technical adjective plastic, which is applied to any material which undergoes a permanent change of shape (plastic deformation) when strained beyond a certain point. Aluminum which is stamped or forged, for instance, exhibits plasticity in this sense, but is not plastic in the common sense; in contrast, in their finished forms, some plastics will break before deforming and therefore are not plastic in the technical sense. There are two types of plastics: thermoplastics and thermosetting polymers. Thermoplastics will soften and melt if enough heat is applied; examples are polyethylene, polystyrene, polyvinyl chloride and polytetrafluoroethylene (PTFE). Thermosets can melt and take shape once; after they have solidified, they stay solid. From Wikipedia under the

Having worked in a recycling plant, I can tell you something. The PET or polyester drink bottles are bailed and shipped to the plant. all other plastics must be sorted pretty much by hand. It was done in a large building with people and conveyors. Sometimes it is mixed with metal which has to be removed. Then it goes through a shredder and is blown through pipes that has magnets to catch some of the metals. It is perfectly dried then goes into a screw extruder, heated forces through dies. Some for fiber some for plastic pellets which are sent to off for molding. Ir the fiber is chopped up into staple for rugs and other products.
