The gradual decrease in the capacity of landfill sites necessitates the use of alternative disposal methods instead of the storage for disposal of industrial treatment sludges, which are not classified as hazardous and non-combustible wastes. The use of these wastes in other industrial areas as a raw material or raw material additive is an important research area, at the present time. By this usage, disposal cost reduction and landfill usage period increments will be provided. In this study, firing process stack emissions are investigated when using automotive industry treatment sludge as an additive to brick raw material. Chemical treatment sludge, which is categorized as non-hazardous according to the General Fundamentals Relating to Waste Management Regulation (GFRWMR) Appendix-3-B, does not adversely affect the product quality, with additive rates of 5% and 10 to raw material, according to experimental studies on field-scale experimental brick production. During the firing process, stack gas emissions were sampled and measured according to the Industry Originated Air Pollution Control Regulation (IOAPCR), and the Hazardous Waste Control Regulation (HWCR). According to the measurement results, chemical treatment sludge as an additive to the raw material was determined as a useful recycling option; however, it should be monitored according to variable process conditions.
