Shredding discs can make plastic pellets
The whole body of waste CDs is a treasure
The whole body of waste CDs is a treasureThe finished disc is composed of base material and metal coating
.
Waste discs are treasures all over the body, from the base material to the metal coating can be recycled

The CD Recycling Center of America in Salem, New Hampshire, where used records are shipped in bundles every day, and then made into polycarbonate plastic pellets (PC), which are finally used to make cars, homes Durable items such as building materials and glasses
.
As the largest destination country for waste plastics in developed countries, China has restricted the import of cardboard and most plastics since 2018, making polycarbonate plastic pellets made from CDs recycled by CD recycling centers in the United States nowhere to be sold
.
As a result, some domestic organizations, such as GreenDisk, provide drop boxes for discarded CDs and other outdated technology
.
Globally, recycling CDs is not currently a significant environmental priority, said Judith Enck, a former U.

domesticAt present, the domestic disposal methods for waste CD-ROMs are mainly landfill and incineration
.
Simple incineration of waste discs will easily produce carcinogenic substances - dioxins, causing air pollution.
At the same time, dioxins are very stable and have a high melting point.
They are extremely insoluble in water and can be dissolved in most organic solvents.
It is a colorless and odorless fat-soluble substance, so it is very easy to accumulate in the living body and is harmful to the human body
.
Today's worldwide oil crisis has made the prices of polycarbonate petrochemicals continue to rise.
Such a simple disposal method is obviously a great waste of resources
.
Under the background of China's rapid economic development, the problem of waste optical discs has become increasingly prominent.
Reasonable recycling and resource utilization of waste optical discs are of great significance for saving raw materials and protecting the environment
