PROCESS FOR CLEANING DIRTY POST-CONSUMER WASTE GLASS

摘要

A method is provided to clean glass mixed with non-glass undifferentiated trash. In the method, the glass pieces are kept as large as possible to thereby minimize the amount of surface area that needs to be cleaned. The glass pieces are cleaned without washing the glass pieces with water or a surfactant during the cleaning process. The non-glass contaminants are liberated from the glass by drying and abrasion, and then removed from the glass by screening and density separation.
