The generation of a large and diverse amount of waste by industries, coupled with the depletion of natural resources, necessitates the need to analyze, create, and implement effective treatment mechanisms. This can help recover and reuse materials and substances, thereby reducing the negative impacts caused by waste disposal on the environment. The leather processing industry, also known as tannery, is a major polluter due to the use of dangerous and heavy materials in its processes. Among the available alternatives, incorporating waste into cement matrices can be a promising solution. Therefore, this study aims to investigate the partial replacement of residual water treatment sludge from a tannery company with cement for cost-effective and feasible management of hazardous contaminants. The research will explore three different scenarios, including sludge with varying moisture content, ash obtained through incineration, and moist oxidation. For each scenario, cement samples will be created with 0%, 3%, 5%, 7%, and 10% replacement of cement with the sludge, and their mechanical resistance, flexion and compression, chemistry, solubility, and leaching properties will be evaluated.
