<p>In Tamil Nadu, large quantities of chemical/Biological sludge are generated from Tirupur Common Effluent Treatment Plants (CETP) and are lying in CETP premises awaiting disposal to landfill, endangering human health and the environment (Aneesh Narayan et al. 2017). the CETPs are spending considerable amount in disposal of the sludge at the chemical plants. There is a growing need to find alternative solutions for the CETP chemical sludge management. The construction industry in India is one of the biggest industries and is responsible for overall infrastructure development of the nation. India is expected to become the third largest country in the construction field. The manufacturing process of various building components in large volumes necessitates extensive resource depletion and subsequently lead to generation of million tons of waste products. For the manufacturing process, high energy is required resulting in large CO₂ emission. Therefore, utilization of waste materials in the manufacturing of construction materials with minimal energy usage is the need of hour. This study investigates the viability of using CETP chemical sludge in place of cement or fine aggregates when making hollow concrete tiles and blocks. The CETP chemical sludge is a possible supplemental cementitious material because it contains siliceous and aluminous compounds that may show pozzolanic behavior (Singh 2019 and Kaosol 2010). In order to improve construction sustainability and address the disposal of Textile Industrial waste, this study explores the use of CETP chemical sludge from textile Common Effluent Treatment Plants (CETPs) as a partial substitute for cement / fine aggregates in the production of concrete and building materials (such as hollow blocks and tiles Mandlik and Karale (2018) and&#xa0;Lukose (2022), analyze its mechanical characteristics. Workability, compressive strength, water absorption, efflorescence, and other fresh and hardened properties were assessed using standard laboratory tests. For hollow blocks, CETP sludge can be used as a partial replacement for cement for non-structural applications upto approximately 12%. For tiles, CETP sludge can be safely used as a partial replacement of Cement up to 5% without affecting compressive strength. The findings show that while higher replacement levels result in a decrease in strength, limited partial replacement of cement with CETP sludge may be possible for certain applications. The project reduces waste and cement consumption while showcasing the potential of CETP sludge as a sustainable resource for green building materials.</p>
