Recycling and dismantling of scrapped cars in China

2020-09-15

Genbrug og demontering af udrangerede biler i Kina håndteres hovedsageligt af specialiserede skrotbiler til genbrug og demontering. Ud over genanvendelse af skrotbiler er demontering, brikettering og skrotstålsforarbejdning alle afsluttet i demonteringsfirmaerne. De demonterede gamle dele fortsætter med at cirkulere og sælge, og karrosseribriketterne og det primære forarbejdede stålskrot sælges til stålvirksomheder.

Scrap cars are generally purchased directly from car owners by scrap car recycling and dismantling companies, mainly through the business personnel of the scrap car recycling companies to provide services to the car owners, including the agency for the cancellation of vehicles to obtain the source of scrap cars. A very small amount of waste cars are directly handed over to waste car recycling companies by car owners, which is similar to the situation in my country. The price is negotiated between the buyer and the seller. The average price of each scrap car is about RMB 330. There is no geographical restriction on the purchase of scrap cars. Competition among recycling companies is fierce. How to receive enough scrap cars is the company's most important task for survival. Therefore, all companies regard the methods and methods of collecting vehicles as trade secrets. After the scrap car company recycles the scrap car, it will issue a "Car Recycling Certificate" to the car owner, and the car owner will go to the relevant vehicle management agency to go through the car cancellation procedures based on the certificate. The license plate was destroyed on the spot by the waste car recycling company.

After the scrap car recycling and dismantling company acquires scrap cars, it first disassembles and collects hazardous wastes such as air conditioners, batteries, and waste engine oil, and takes measures to dispose of them separately according to environmental protection requirements; then disassembles the old parts that can be used In the end, stockpiling, sales, and dismantling of old parts are basically not inspected and processed. During the transaction, the quality and value of the parts are judged based on the experience of the buyer and the seller, and the price is negotiated. Currently, relevant laws in South Korea prohibit the circulation and reuse of engines, steering gears, and braking systems. However, in the two scrap car dismantling companies we visited, these three parts were dismantled for export or domestic sales. This is the place where South Korea’s current scrapped car recycling supervision is weak. Used parts are mainly sold to Southeast Asia, The Middle East and other regions are said to have also been sold to my country's Anhui Province (in fact, it should be said that it is smuggling). After dismantling the car seats containing non-metallic materials, they are incinerated in a waste car recycling company. Disassemble the remaining body and press it into pieces at the scrap car company. Scrap car blocks are generally sold to steel companies for recycling, and some are sliced and broken by scrap car companies before being sold.

At dømme ud fra besøg på stedet er ledelsen af ​​koreanske skrotede bilafviklingsfirmaer ret kaotisk, og overtrædelser af regler er almindelige. Dette er meget forskelligt fra situationen i Japan.

Brikettering af skrotbiler bruges hovedsageligt i skrotbilgenbrugsfirmaer, jern- og stålvirksomheder eller professionelle metalskæringsanlæg til at skære, knuse og sortere. Metal smash leveres til skrotmetal applikationsvirksomheder, som indeholder mange urenheder. Hvis det leveres til stålværker til stålfremstilling, er det nødvendigt med yderligere sortering og forarbejdning. Andet ubrugeligt affald bruges til forbrænding eller deponering.

Beregnet efter vægt udgør genbrug af dele og komponenter 20-25% af affaldsbilens vægt, og vægten af ​​de ødelagte genstande tegner sig for 75-80%, hvoraf 75% er metalstrimler, og de resterende 25 % (plast, glas osv.) deponeres eller brændes.
