Brazil is one of the references in the world market of ceramic tiles, ranking second in production and consumption. Only in 2012 were produced 865.9 million square feet, for a total installed capacity of 1.004 million square meters. An important aspect of the ceramic industry in the global context, is the continuous technological development, the widespread use of ceramics in various applications and environments and the increasing incorporation of waste from other sectors, giving sustainability concepts in the industry. Brazil produces on average 980 000 tonnes of glass packaging a year and has about a recycling rate of 47%. This study aimed to present one more option to the use of waste glass, which is still poorly recycled in Brazil, analyzing the influence of the replacement of feldspar in a ceramic, for residue from glass bottles are not returnable to the market. We tested three different percentages of glass waste, but also the influence on the behavior of the residue the technological properties with variation of firing temperature. Previously, all materials used in this work were characterized by the techniques of X-ray fluorescence, X-ray diffraction, thermal analysis and particle size. After established formulations, manufacturing and burning the bodies of the test piece, checked the technological properties and microstructure of established formulations. The results indicate that the glass waste has the potential to be used as a flux alternative to replace feldspar in the production of ceramic tiles for different purposes, according to NBR 13817/1997.
