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. China has stipulated the standards for automobile scrapping, and cars in one of the following cases should be scrapped.
Talking about the production of automobile plastic waste
(1) Accumulated mileage
Mini truck (including off-road type) and special truck for mining operation: 30X10^4km;
Heavy and medium-duty trucks (including off-road type): 40X10^4km;
Various passenger cars (including off-road type) and cars: 50X10^4km;
Other vehicles: 45X10^4km
(2) years of use
Mini-loading vehicles (including off-road type), trucks with trailers, special trucks for mining operations and various types of taxis: 8 years;
Tourist passenger cars and more than nine non-operating passenger cars: 10 years;
Non-operating passenger vehicles (including cars and off-road vehicles) of nine seats (including nine seats): 15 years.
(3) The vehicle is seriously damaged or the technical condition is inferior and cannot be repaired.
(4) The model is eliminated, no accessory source.
(5) The fuel consumption exceeds 15% of the factory standard.
(6) Failure to meet the requirements of the safety standards for Motor vehicle operation.
(7) After repairing and adjusting or adopting exhaust pollution control, it still exceeds national emission standards.
It can be seen that the scrap rate of the vehicle is quite considerable. For example, according to the average service life of the vehicle for 10 years, the scrap amount of the vehicle is about 10% of the possession. According to the world's car ownership of about 700 million vehicles, this is a huge amount.
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.
