Glass can be removed from municipal refuse as cullet for use in the manufacture of new glass containers. Among the four U.S. resource recovery plants designed for recovery of cullet, three will employ a froth flotation process and will produce a color-mixed cullet. Color-mixed cullet contains iron and chrome oxides used in coloring amber and green container glass. Limits to the use of color-mixed cullet are calculated based on reported concentrations of iron and chrome oxides in recovered cullet and on tolerances for these chemicals in container glass. The use of color-mixed cullet in flint (clear) container glass is limited primarily by the concentration of chrome oxide in the cullet. Approaches to expanding this limit and for monitoring chemical colorant levels in cullet are reviewed.
