The construction of plastic closed loop is urgent

- Jun 18, 2019-

The development trend of the industry requires the electronic and electrical enterprises to pay attention to the easy cycle design of plastic parts, so as to be easy to disassemble, sort and sort.

It is required that disassembling enterprises reasonably plan the technological process and classify the disassembled plastic parts.

It requires recycling enterprises to clean and separate efficiently to ensure the purity of recycled plastic particles, which can be easily used in the processing of electronic and electrical plastic parts.


In 2018, more than 10 million tons of plastics for household appliances and modified plastics will be used. The construction of closed-loop of plastics for electronics and electrical appliances will greatly improve the recycling ratio of the industry and the application level of recycled plastics.


More than 25% of the waste plastics of mixed electronic appliances cannot be sorted


According to statistics, more than 10 million tons of plastics were used in household appliances in China in 2018, of which ABS, HIPS, PP, PC&search_type=1"style="color:#3f89f7;

Target ="_blank"title="ABS/PC">ABS/PC, AS, PC, PA, POM, PET and reinforced PBT plastics are commonly used.


According to the current technology of household appliances disassembly, most of them are manually disassembled, and some are simply disassembled and most of them are crushed to separate metal, plastic and other materials. Generally, the separation of waste household appliances and plastics will use a combination of multiple separation methods, such as density separation, electrostatic separation, color separation and photoelectric separation.

Even a variety of sorting methods, there are more than 25% of mixed plastic waste appliances can not be sorted.

According to the consumption of 10 million tons of electronics and electrical appliances in 2018, more than 2.5 million tons of mixed plastics were discarded into the environment or incinerated, causing serious waste of resources.


For this reason, the plastic recycling chapter of China synthetic resin association proposed that the design specification of easily recycled plastics for household appliances should be compiled, so as to design easily recycled plastics from the source of household appliance enterprises, improve the recycling rate, reduce the dependence of recycling on high-tech equipment and investment, and improve the overall social efficiency.


Second, the home appliance dismantling industry is facing larger scale integration and further improvement of the fund system


The national development and reform commission, the ministry of ecology and environment, and the ministry of commerce jointly issued the "implementation plan for promoting the upgrading of key consumer goods and the smooth recycling of resources (2019-2020)," which stressed that the regulations on the elimination of old products should be strictly implemented, and efforts should be made to improve the recycling and dismantling system of waste products.

We will push forward the reform of funds for disposing of discarded electrical and electronic products, and actively defuse business pressure on dismantling enterprises.

We will accelerate the establishment of information security management standards for used electronic products, establish a supervision mechanism for remanufacturing enterprises and products, and constantly improve the utilization level of used product resources.


This is after the introduction of the fund system, the state explicitly put forward in the official document "promote the reform of waste electrical and electronic products disposal fund", release an important signal!

The dismantling industry is a major positive.


For disassembly enterprises, the specification and process management of plastic parts disassembly is a good time to practice internal skills.


3. The national standard for reprocessing plastics will be issued soon, which requires that the rohs-related limit requirements be met, which may have a substantial impact on the factories that export recycled plastics for electronic appliances to China.


There are different requirements for the content of heavy metals and other hazardous substances in global electronic and electrical appliances, including strict requirements in Europe and Japan, different requirements in the United States, and basically no clear requirements in Africa and southeast Asia. Recycled plastics from waste plastics of electronic and electrical appliances may exceed the standard due to the presence of a large number of flame retardants.


The national standard for reprocessing plastics will be issued soon, which requires that the rohs-related limit requirements be met, which may have a substantial impact on the factories that export recycled plastics for electronic appliances to China.


Iv. With the completion of the Basel convention revision, the global waste industry will undergo a new round of changes, and the global supply may continue to decline


The Basel convention amendment, which will come into force in 2021, will have a substantial impact on the global waste trade and the supply of recycled materials. The global supply of recycled materials is likely to continue to decline, especially ABS, hips, PP and other types of waste plastics derived from household appliances. Domestic recycled materials derived from electric waste will be welcomed.

It is more feasible for disassembling enterprises to enter regenerative granulation industry.
