Automotive plastic waste is a kind of plastic waste. It has the common feature of general plastic waste, that is, it is produced in the entire chain of resin production → special material production → molding processing → consumption (application) → scrapping (elimination). of. And scrapped vehicles are the main source of automotive plastic waste.
German Volkswagen has conducted research, a car with a total mass of 1150kg, which is roughly 540kg steel shaft, 130kg cast iron, 75kg forged parts, 80kg light metal, 120kg plastic, 90kg rubber, 50kg glass, 30kg paint (paint) and Others (mainly wood, fiberboard, leather goods, etc.). Plastics account for about 10.4%. In Western Europe, the amount of automotive plastic waste in 1995 was 888 kt, accounting for 5.5% of total plastic waste. The United States scraps about 11 million cars a year, producing 11,200 kt of steel, 800 kt of scrap iron, 3,500 kt of crushed residue, and 1,100 kt of plastic.
50-60 thermoplastics and thermosetting plastics are generally used in each automobile, mainly PP, PE, pvc, PU, ​​abs, PC, PPO, PBT, PTFE, SMC, and glass fiber reinforced polyester, polyamide, and the like. There are as many as 800-1000 plastic parts on the car, and the weight of one piece is about 5kg, and the light is only a few grams or even less than 1R.
However, unlike general plastic waste, automotive plastic waste is generated along with the scrapping of automobiles. As long as the measures are right, they can be disassembled, sorted, and recycled. The general plastic waste mainly comes from urban waste. The variety is complicated, the nature is different, and the pollution is serious. It must be collected, separated, cleaned, dried, crushed, granulated and densified to be recycled. It is difficult. To increase.
