Title:
METHOD OF RECYCLING GLASSWARE AND APPARATUS FOR THE SAME
Document Type and Number:
Japanese Patent JP2007260566
Kind Code:
A
Abstract:

To provide a method of recycling glassware by which glass cullet with good quality sufficient to use the cullet as a raw material for glass can be recovered from glassware bearing an organic compound or a polymer compound and apparatus for the method.

Laminated cullet packed in a cartridge 12 is loaded to a glass melting furnace 50 and heated in a batch treatment manner with a high-temperature gas (hot air blow) at the glass softening point or higher (not lower than 700°C and not higher than 1,000°C, preferably not lower than 800°C and not higher than 900°C) for 1 to 8 minutes in the glass melting furnace 50. Accordingly, since the organic compound or polymer compound is thermally decomposed before the glass is softened, the glass cullet can be obtained efficiently. Further, the organic compound or polymer compound is completely removed, glass cullet with a quality high enough to use the cullet as a glass raw material can be obtained.
