Abstract:
As the process generates some waste, the recycling market has been growing, as environmentally correct forms of disposal are needed. Given the above, it is essential to find ways to reuse waste, and an alternative would be incorporation into the ceramics industry. Thus, the objective of this work was the incorporation of a so-called combustible waste (jabuticaba peel) and a flux waste (packaging glass) in a ceramic mass, evaluating the properties of fired ceramics. The raw materials were evaluated by FRX. The raw materials were dried and sieved so that formulations could be made with different percentages of wastes, which were burned at temperatures of 750 and 850ºC with a rate of 3ºC/min and kept at the plate temperature for 180min. Afterwards, the following properties were evaluated: water absorption, linear shrinkage, and three-point bending stress. The thermal behavior of the formulations was evaluated by linear dilatometry. With the results obtained, it was observed that because it is a waste with a large amount of organic matter, the jabuticaba peel alone would harm the properties of ceramics, and should only be used in small quantities. When blands were made with the two wastes, even burning at lower temperatures, there was a significant improvement. With this, it is possible to conclude that the incorporation of the mixture of the two wastes in ceramics is a very advantageous alternative, both from the environmental point of view, for the disposal of these wastes, and for the ceramic industry, where in addition to improving the quality of the pieces, it has savings energy in the burning process
