Title:
TREATMENT OF CHLORINE-CONTAINING PLASTIC SCRAP
Document Type and Number:
Japanese Patent JPH08290147
Kind Code:
A
Abstract:

PURPOSE: To provide a treating method capable of reutilizing by dechlorinating a shredder dust or the like without generating harmful chlorine compounds such as dioxin to convert an organic waste into fuel and further recovering the metallic portion as a source.

CONSTITUTION: In the treating method for converting a plastic scrap into fuel by carbonizing, the chlorine-containing plastic scrap is carbonized in the presence of metallic chips under a non-oxidizing atmosphere at 300-600°C. Chlorine contained in the plastic scrap is fixed in a residue to be separated from the carbonized gas by allowing the chlorine to react with the metallic chips to produce a metallic chloride nonvolatile at the carbonizing temp. and to recover the effluent and on the other hand, the water soluble metallic chloride is dissolved and removed by washing the carbonized residue and dechlorinated.
