Abstract: A method of processing cathode ray tube (CRT) glass with waste glass into a pozzolanic mixture includes, receiving CRT glass aggregate, pulverizing the CRT glass aggregate forming an intermediate CRT glass product, fine grinding the intermediate CRT glass product into a powder, receiving waste glass, pulverizing the waste glass forming an intermediate waste glass product, fine grinding the intermediate waste glass product into a waste glass powder, and combining the waste glass powder with the CRT glass powder by weight or volume to form the pozzolanic mixture. The pozzolanic mixture may be used in place of Portland cement in a cementitious mixture. Also, a leaded portion of the CRT glass may be used in the cementitious mixture to act as a radiation barrier.

Abstract: A method is provided to clean glass mixed with non-glass undifferentiated trash. In the method, 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.

Abstract: 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.

Abstract: A method of making an alkali glass powder includes obtaining down chute waste fiberglass (DCWF) and post-consumer waste glass (PCWG), processing the DCWF into a DCWF particulate form, combining the DCWF and PCWG at a ratio of PCWG to DCWF, and co-grinding the combined DCWF particulate form and the PCWG into a DCWF-PCWG powder having an alkali content based on the ratio of PCWG to DCWF.
