Since LCD glasses are produced using relatively high purity raw materials to ensure display quality, they not only contain few impurities, but are also highly homogenous. These two characteristics of LCD glasses can offer a recycling possibility for their cullet as a raw material for some commercial glasses in terms of savings in raw material costs and energy. In this work, several batches, containing LCD glass cullet, for E-glass and glass wool were prepared and melted in the laboratory. Viscosity and liquidus temperature were determined for these glasses. In the case of E-glass, there was no serious change in both properties up to 25 wt% replacement of original glass by LCD cullet. Glass wool could accept LCD cullet up to 20 wt% of total glass. Since 2010, LCD glass cullet has been used in some E-glass production plants in Korea.
