Title:
HIGH SPECIFIC GRAVITY PLASTIC SEPARATION METHOD FROM PLASTIC MIXTURE
Document Type and Number:
Japanese Patent JP2011031545
Kind Code:
A
Abstract:
To provide a method of carrying out the specific gravity separation of a high specific gravity plastic including the form of a film.
The method of carrying out the specific gravity separation of a plastic mixture in a liquid includes: the oxidation treatment process which performs the oxidation treatment of the plastic mixture in a gas or liquid; and the process degassing process which eliminates bubbles attached or included in the plastic mixture after the oxidation treatment process. The high specific gravity plastic is thereby separated from the waste plastic mixture in which the high specific gravity plastic including the form of a film has been mixed.
