The article presents research on the possibility of using troublesome waste such as: sewage sludge, mineral fraction of municipal waste <10 mm, stabilizer after mechanical-biological processing (MBP), carbon waste, glass - as a flux in the production of new light ceramic materials. Clay was used as the basis of the material. In order to determine the possibility of using individual materials to produce a ceramic material, the oxide composition of individual components was examined using the XRF method. XRF analysis showed the presence of quartz and aluminosilicates in the materials, which makes it possible to use these wastes to produce new materials. Then the waste was ground in a ball mill and mixed in different proportions by adding water and three different materials were obtained. Material A: clay, sewage sludge, waste water, glass. Material B: clay, mineral fraction of waste <10 mm, flotation waste, glass. Material C: clay, stabilizer after mechanical-biological processing, post-mining waste, glass. The materials were subjected to strength and absorbability tests. The most stable was Material B. The highest variability of properties was observed in Material A. On the other hand, a high heterogeneity was observed in Material C. The bulk density for all materials was 658kg/m³ on average.
