Recycling, plastic

This is the process of recovering scrap or waste plastics and reprocessing the material into useful products. It has been estimated that every tonne of plastics bottles recycled saves about 3.8 barrels of oil. Recycling is therefore seen as very eco-friendly. 

other plastics including acrylic, ABS, nylon, fibreglass and polycarbonate. 

Sheet plastics material may require to be fabricated, in which case sheets can be joined by welding. 

Local councils primarily target bottles and containers as they represent the largest usage and are easy to identify and separate, usually 1 and 2. 

If you look at the base of a plastics bottle or container, you will see a triangle containing a number together with letters identifying the type of plastics material. 

Bulk molding compounds (BMCs) are similar in composition to SMCs, with somewhat shorter fibers (V4 to V2 in), and perhaps less glass (15%) and more filler. They are produced in chunk form and compression molded like other thermosetting compounds.

Price swings, particularly in the PET and HDPE markets have contributed to a retrenchment in the U.S. plastics recycling industry in 1995—1997... 

These lower prices make it more difficult for recycled plastics to compete with virgin resins in the absence of legislation mandating plastics recycling.

A 20ft-high mini plant has been built at BP s refinery at Grangemouth, near Edinburgh, as an experiment by several leading European petrochemical companies to address the difficult issue of plastic recycling. The 7501/ y pilot plant accepts mixed plastics ground into pieces a maximum of 2cm across and passes them over hot sand which converts them into a gas. This is distilled back into plastic feedstock which can be fed back into the petroehemical plant to make fresh plastic. This process eould be replieated at many small plants, located at ehemieal works or even beside municipal waste tips.
