Environmental and economic value of waste plastics

The average service life of home appliances is 10 to 15 years.
The average number of TV sets that need to be scrapped per year is more than 5 million sets, the average number of washing machines is 5 million sets per year, and the number of refrigerators is about 4 million sets per year.
Therefore, China will eliminate more than 15 million sets of waste every year.

.
In recent years, the replacement of electronic communication equipment such as computers, mobile phones, VCDs, DVDs, records, and CDs has accelerated, and the number of scrapped items has risen sharply every year, which has brought serious environmental problems
.

Plastic is an important part of household appliances, and the annual amount of renewable plastic produced is at least 150,000 tons.
If you take into account the amount of renewable plastic in scrapped electronic communication equipment, the figure is about more than 200,000 tons
.
The main components of these recycled plastics are polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), ABS, etc.
, which are of great recycling value; while some thermosetting plastics, foamed polyurethane, and glass fiber reinforced plastics are Relatively difficult to recycle
.

Reasonable disposal of recycled plastics in the recycling process of waste household appliances is one of the important links
.
The types of plastics used in different household appliances are not the same.
The same product uses different types of plastics due to different manufacturers.
Sometimes the same type of plastics uses different additives, functional masterbatches or formulas.
Recycling has caused certain difficulties, which must be taken seriously, and strive to achieve effective recycling, so as to reduce environmental pressure and energy waste as much as possible
.

The consumption of plastic accessories for electronic and electrical appliances has reached more than 1 million tons
.
As such products gradually enter a large number of end-of-life periods, they have become an important source of waste plastics
.

Recycled plastics are different forms of plastic that exist according to their value for recycling after their useful life, and almost all thermoplastics have recycling value
.

Recycled plastics are produced during the production of synthetic resins, during the production and processing of plastic products and semi-finished products, during the logistics of plastics and after use by consumers
.
Generally, those produced during synthesis and processing are called pre-consumer plastics; those produced after circulation, consumption, and use are called post-consumer plastics
.
Pre-consumer plastics have a small amount of production, stable quality, and high recycling value.
Generally, they are properly disposed of during the production process and can be completely reused
.
What we call recycled plastic generally refers to recyclable plastic products that lose their use value after consumption and can be recycled
.
After recycling, concentration, classification, and scientific and reasonable disposal of plastics, plastics can obtain renewable value and realize recycling
.

The waste plastic industry, or the industry chain, is closely related to all fields of the existing economic field, and is interdependent, co-existing, and developing relatively synchronously
.

The global recycling system is an inevitable part of the ecological chain of people's daily life and economic life.
If any link is destroyed, it will touch or destroy the ecological balance and progress
.

China is inseparable from the waste plastic industry, and it is also inseparable from the thousands of people who still stick to the waste plastic industry!
