CD Material
Processing - De-metalizing each disc
At the
central collection point, or warehouse, incoming discs are
stored for processing in a wet chemical operation. Here the
discs are washed, completely de-metalized and dried, then fed onto
a conveyor belt for quality inspection to make sure that the
coating is completely removed and the disc is ready to be crushed
into small particles, ready to be sold or reused in an injection
molding process.

The demetalized discs are next granulated to produce a flaked
end-product, as shown here:
This
material might be called “recycled, Hi Grade Polycarbonate” or
Demetalized, Hi Clarity Polycarbonate.” Polycarbonates are among
the toughest and most flexible polymers known. They command the
highest prices in virgin form because the material is optically
clear and can be used in CD and DVD production.
Recycled polycarbonate resin, however, cannot be guaranteed as
optically clear, hence it cannot be used for discs, but it is
clear enough for sunglasses and can be colored for use in a
variety of applications, such as toys, machine parts, or any
product that needs a tough, almost unbreakable plastic which
conforms to the material specifications of polycarbonate.
Toymakers, for example, can replace brittle, breakable
polystyrene toys with the superior polycarbonate material that
this recycling stream generates. Protective freeway and
electronic sign covers and street light lenses are other
important uses. |
