Turkey is the fifth biggest ceramic tile exporter in the world. Considering the expectation that the Turkish tile sector continues to expand, further studies both on the improvement and the development of tile formulations are necessary in order to make the producers advantaged in the world market while maintaining the capital and running costs at reasonably competitive levels as well. In addition to such studies, waste management in tile manufacturing has also recently become an important issue. Accordingly, the industrial use of wastes in the traditional ceramic industry has been intensively investigated in the recent years. This work describes part of a detailed research project carried out jointly on the possible re-use of muds (raw production waste) from glazing and pressing lines of a local tile company in the development of new wall and floor tile formulations. In order to achieve this, the waste material was firstly investigated in function of chemical and mineralogical compositions. Then, the particular focus was given to the presence of the waste material in increasing amounts on the thermal behaviour and physicomechanical properties of the re-formulated tile bodies. During the studies, SEM in combination with EDS, and thermal analysis techniques such as non-contact dilatometry were widely employed. The results indicated that it was possible to use the waste materials in the commercial tile production without deteriorating the relevant technological properties.
