Abstract

Green glass content of mixed color glass cullet is selectively decolorized by using copper oxide and is used as an input component in a conventional glass production process. To determine how much copper oxide to add, the weight percent of green glass in the provided glass cullet supply is determined and an effective amount of copper oxide to, at least partially, decolorize the green glass is determined wherein an effective amount is determined using a non-linear inverse prediction model between the weight percent of green glass or chromium and/or iron content and the copper oxide. The amount of copper oxide is thus non-linearly adjusted for increasing levels of green glass in the glass batch. To compensate for the darkening of the glass by the additional copper oxide, the redox of the glass may be made slightly less reducing as the amount of chrome and copper is increased.
