Soda-Lime Glass from 100% Recycled Glass-Forming Materials

Abstract

A glass food and beverage container constructed of 100 wt. % recycled glass-forming materials selected from the group consisting of post-industrial cullet, post-consumer cullet, and a combination thereof.

1 . A glass food and beverage container constructed of 100 wt. % recycled glass-forming materials selected from the group consisting of post-industrial cullet, post-consumer cullet, and a combination thereof. 
     
     
         2 . The container set forth in  claim 1  wherein the glass-forming materials include substantially no virgin raw materials. 
     
     
         3 . A glass container comprising:
 a soda-lime glass wall that provides the container with a body, a circumferentially-closed base at one end of the body, and a mouth at another end of the body opposite the circumferentially-closed base, the soda-lime glass wall having a glass composition that includes a main oxide content of about 60-75 wt. % SiO 2 , about 10-18 wt. % Na 2 O, and about 5-15 wt. % CaO, and wherein the main oxide content of the glass composition of the soda-lime glass wall is derived only from cullet.   
     
     
         4 . The glass container set forth in  claim 3 , wherein the main oxide content of the glass composition of the soda-lime glass wall is derived from pre-sorted cullet that comprises 40-50 wt. % green glass, 40-50 wt. % flint glass, 5-15 wt. % amber glass, 0-2 wt. % blue glass and other colored glass, and less than 250 grams/ton of opal glass 40-50 wt. % green glass. 
     
     
         5 . A glass container comprising:
 a soda-lime glass wall that provides the container with a body, a circumferentially-closed base at one end of the body, and a mouth at another end of the body opposite the circumferentially-closed base, the soda-lime glass wall having a glass composition that includes a main oxide content of about 60-75 wt. % SiO 2 , about 10-18 wt. % Na 2 O, and about 5-15 wt. % CaO, and wherein the main oxide content of the glass composition of the soda-lime glass wall is derived only from cullet.   
     
     
         6 . The glass container set forth in  claim 5 , wherein the main oxide content of the glass composition of the soda-lime glass wall is derived from pre-sorted cullet that comprises 40-50 wt. % green glass, 40-50 wt. % flint glass, 5-15 wt. % amber glass, 0-2 wt. % blue glass and other colored glass, and less than 250 grams/ton of opal glass 40-50 wt. % green glass.
