An apparatus for plastic recycling machines   or decompstiong waste plastic is decomposed in a diluent such as hot oil through actions involving free readical precursors, such as polyvinyl chloride or polyurethane is achieved at low temperatures. The thermal decompostion (or pyrolysis) reaction is for about 1 hour at 375° C. annd usable products, such as distillate, coke and oil are recovered. Additonally the diluent my ber recycled within the apparatus. Waste plastics, that is synthetic polymer-containing substances, pose an environmental issue because of the problems associated with disposal: a large volume of non-biodegradable material. Because of the limits on landfill capacity, future recycling or decomposition is a necessity. Direct recycling back to the manufacture is not always feasible because such waste plastic is often mixed with respect to polymer type and separation is uneconomical. Economical considerations for processing waste plastic often require the use of the unseparated mixed waste plastic. Plastic recycling originated with the manufacture of synthetic thermoplastics. Rejected parts, trim, and flash from operations represented valuable materials that were ground and recycled with virgin material. This process was potentially repeated a number of times provided the percentage of regrinds remained low. As long as the plastic scrap generated by the industry was clean and uncontaminated with other plastics, reprocessing within the industry continued to expand, provided the price of virgin plastic remained high. After 1960 with a decrease in prices, profit margins for plastic scrap were squeezed, and disposal instead of reprocessing often occurred.

Plastic is one of the most used materials in today's world because of its properties as lightweight and durable material. Its popularity, however, is also its curse. We are using more plastic products than ever before and filling our landfills with plastic waste that does not biodegrade for centuries.plastic recycling line , however, is one of the easiest ways for you to be environmentally friendly, and recycling and lengthening the lifespan of plastic products are important for the health of our planet.Many everyday items are made of plastic and are easily recyclable in most recycling facilities. Most common recyclable plastic products are beverage bottles used for water, soda and juice, plastic bags and plastic containers that come with many food products. Just wash all the plastic items and then separate them based on their resin identification codes.

After 1970, plastic prices rose again due to OPEC raising the cost of petroleum feedstocks and recycling practices again increased. Interest increased not only in processes for reclaiming waste plastics, such as product evaluation for chemicals and fuels, but also in the necessary step of separation of plastics from other waste material. A review of this early history of plastics recycling is given by R. J. Ehrig in Plastics Recycling, Oxford University Press, N.Y., 1992, hereinafter referred to as Ehrig (1992). Some of the early operating plants for Waste plastic recycling   included a Department of Energy funded plant in LaPorte, Tex., which used a fluidized bed of sand and was designed for 17 million pounds per year of atactic polypropylene. It ran from 1980-82. In 1984 at Ebenhausen, Germany, a 20 million pound per year plant used molten salt with a fluidized bed reactor to process plastic wastes and tires.
