	The incorporation of pore-forming agents in brick manufacturing contributes to reducing the consumption of natural resources while improving the properties of the material, including lowering its density and thus improving its thermal insulation properties. In this study, agro-waste (corn stalk digestate – CSD) and sanitary ceramic waste (SCW) were used as additives for the production of ceramic bricks. The bricks were produced by varying the amount of D (2, 4 wt%) and C (30, 40 wt%), which were fired at 1150 °C. In addition to the microstructure test, the water absorptivity, porosity, thermal conductivity coefficient λ, compressive and flexural strength, Young's Modulus, frost resistance, salt resistance and microstructural properties were determined. The highest absorptivity and porosity were obtained on the samples with the highest amount of D4C40 waste, which was 41.7 % and 78 % higher than the absorptivity and porosity of the reference bricks, respectively. The λ values of the bricks were the lowest, at 0.44 W/mK for the D4C40 samples. The largest decrease in compressive strength, of about 32 %, was also observed in D4C40 bricks. Under the freezing-thawing (F-T) environment, the mass loss of brick is low (2.45 % of reference brick B0), but the increase of SCW could increase the F-T resistance of bricks (0.41 % for C30 and 0 % for C40). It is possible to produce ceramic bricks with good performance by using agro-waste (CSD) and SCW, which meets the requirements of cleaner production and brings economic as well as ecological benefits.
