The disposal of sludge from water treatment plants presents significant environmental and economic challenges due to its high moisture content and potential contaminants. This study investigates the feasibility of utilizing water treatment sludge as a raw material in brick manufacturing, offering a sustainable and eco-friendly alternative to conventional clay bricks. By incorporating sludge into brick formulations, this research aims to promote waste valorisation, resource efficiency, and environmental sustainability in the construction industry. A comprehensive characterization of the sludge was conducted to assess its engineering properties and suitability for brick production. Various geotechnical and physical tests, including Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Liquid Limit, Plastic Limit, Grain Size Analysis, Free Swell Index, and Soil Classification, were performed. Based on these properties, sludge was incorporated into brick formulations at varying proportions and processed through moulding, drying, and firing techniques. The fabricated bricks were subjected to performance evaluations, including compressive strength, water absorption, density, porosity, and durability tests. The results were compared with conventional clay bricks to assess the impact of sludge addition on mechanical properties. The findings demonstrated that sludge-incorporated bricks exhibited satisfactory compressive strength and durability, with optimized sludge proportions enhancing their structural integrity. Additionally, sludge utilization contributed to reduced water absorption and porosity within acceptable limits. Beyond technical feasibility, this study highlights the environmental and economic benefits of incorporating sludge into brick production. By diverting sludge from landfills and reducing reliance on natural clay resources, this approach supports the principles of the circular economy and sustainable construction. The research provides a cost-effective and scalable solution for sludge management while offering an alternative building material that meets industry standards. In conclusion, water treatment sludge has the potential to be effectively utilized in brick manufacturing, reducing environmental impact and promoting resource efficiency. Future research can focus on optimizing mix designs, evaluating long-term durability, and exploring large-scale implementation. This study contributes to the development of sustainable construction materials and advances in waste reutilization strategies.
