In the current study, waste marble powder was utilized to produce lightweight fired clay bricks and in the treatment of flue gases. Marble waste powder used in clay bricks and flue gas treatment was collected from local marble processing plants, and its chemical composition was analyzed using energy-dispersive X-ray analysis and X-ray fluorescence. Clay bricks were produced in local fired clay brick kiln by partial replacement (10-40%) of clay with calcined and uncalcined waste marble powder. The temperature in the firing zone of the kiln was 1000-1100 °C. Clay brick properties such as compressive strength, bulk density, porosity, and water absorption were analyzed. Results show that the porosity of clay bricks increases with an increase in marble waste percentage, and due to an increase in porosity, water absorption of clay bricks also increases, while compressive strength and bulk density decrease. Clay bricks with 10% uncalcined marble waste and 20% calcined marble waste satisfy the required Turkish and European compressive strength standard. Marble waste decreases the concentration of sulfur dioxide and particulate matter in flue gases. There is up to 43 and 65% reduction in the concentration of sulfur dioxide and particulate matters, respectively, in flue gases, after treatment with marble waste. The addition of marble waste to clay bricks is an effective and economical solution for waste marble powder management. Furthermore, it can be used for the treatment of flue gases from brick kilns before its addition to clay bricks.
