Global economic growth and population expansion contribute to heightened solid waste production, creating environmental challenges. Sustainable management, notably incineration, is crucial for volume reduction, energy recovery, resource utilization. The escalating reliance on incineration underlines the critical necessity detailed characterization. Our study focuses industrial hazardous residues (IHWA) provides essential insights into their mineral chemical composition employing various analytical techniques, including sieve analyses, laser diffraction, X-ray powder FT-IR spectroscopy, SEM-EDS, leaching behavior, thus contributing filling a gap in current knowledge. majority of IHWA particles (41%) were smaller than 500 μm, with significant portion (34%) 200–400 μm range, which increases potential. Toxic elements, Cr, Cu, Zn, detected at elevated levels, Zn concentrations exceeding EU soil limits by over 250 times, what underscore risks demand proper treatment. complexity bonds within sample indicates thorough assessment understand potential impacts ecosystem. Sequential extraction revealed that (90.32%), Cd (64.22%), Hg predominantly found mobile fractions, indicating high hazards. In contrast, elements like Pb primarily associated immobile fractions. Mineral phases such as calcite halite dissolved during first step, while other crystalline phases, quartz magnetite, remained stable throughout process. stability all results low indicate some could suppress efficiency elements.
