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.

Abstract: A concrete tile and method of making a concrete tile are described. The tile is made by the process of (i) creating a concrete mixture including Portland cement, preferably a pozzolanic glass powder from post-consumer recycled glass which is used as a partial replacement for the Portland cement, and an aggregate, (ii) forming the mixture under vibration and compaction in an elongate mold form having a height, a depth and a width, (iii) curing the molded concrete block, and (iv) cutting the cured block parallel to its height and depth, and transverse to its width to form tiles sliced from the block, with first and second parallel faces and a thickness extending between the faces. The tiles are cut to a thickness of between ¼ and ¾ inch. The resulting tile is uniform in material properties throughout its construction, and is particularly suitable for use on walls and floors.

Abstract: A clean dry white glass powder useful as a substitute for Portland cement in concrete, in paints, and for other known uses for glass powder produced conventionally can be produced from unsorted post-consumer waste glass, including a substantial fraction of non-glass items, by employing glass pulverizing equipment to reduce waste glass to small fragments, allowing removal of trash, employing a multistep washing process to clean the glass fragments, in the preferred embodiment using aggregate cleaning equipment, drying the fragments, preferably using fluidized bed techniques, and grinding the glass to a desired particle size, preferably using a ball mill, in combination with an air classification step to produce a bright white glass powder of uniform particle size.

Abstract: A system and method for handling recyclable materials and products manufactured therefrom is provided. The method includes receiving recyclable material extracted from post consumer and post industrial sources at a manufacturing facility, acquiring information associated with the recyclable material received at the manufacturing facility, such as properties and certification(s) relating thereto, and storing the acquired information in a database for subsequent access. The recycling method may also include manufacturing a product at the manufacturing facility from the recyclable material, generating product information associated with the product such as properties and certification(s) relating thereto, and storing the product information in the database. The product may then be shipped with the product information and certification information stored in a tangible medium to provide quality certified “green” recycled products for use in building construction.

Abstract: A solid surface material suitable for use as a countertop contains a resin and a filler which includes clean dry glass powder produced from unsorted post-consumer waste glass, including a substantial fraction of non-glass items. The powdered glass is used as at least a portion of the filler and/or gelling agent in lieu of or in addition to other fillers and gelling agents known in the art.
