SUMMARY:

Waste management from water treatment plants and the impacts arising from their irregular disposal present current challenges that necessitate alternatives for their proper reuse and disposal. Water treatment plant sludge (WTS), commonly referred to as WTS, poses significant environmental risks when improperly disposed of in riverbeds or watercourses near treatment facilities. Consequently, exploring alternatives to reintegrate this waste into the production chain, thereby enhancing its value, emerges as a critical area of inquiry. Given the substantial volumes of waste generated daily by water treatment plants, the construction industry emerges as a promising sector for utilizing these by-products as raw materials for producing new materials. In this context, this study aims to provide a comprehensive review of the various applications and uses of WTS, outlining its potential contributions across different industries. To achieve this, an extensive search was conducted in the Scopus database to identify relevant scientific literature on the subject. Following the literature review, a rigorous analysis was undertaken to assess both the quantitative and qualitative aspects of the identified documents. Leveraging VOSviewer software, patterns and connections within the literature were explored, providing valuable insights into the current state of research on WTS utilization. Additionally, to contribute to the existing body of knowledge, a simplified life cycle assessment (LCA) was conducted for one of the key by-products within the construction industry. Subsequently, the data obtained were subjected to thorough statistical analysis using Jamovi 2.3.21 and Statistica 10 software, enabling a deeper understanding of the implications and potential applications of WTS in construction. The findings revealed a range of viable solutions for incorporating WTS into construction materials, including composites, supplementary cementitious materials, aggregates, ceramics, geopolymers, and geotechnical applications. Overall, the study underscores the diverse opportunities for leveraging WTS in the construction industry to develop innovative products while addressing considerations of safety, durability, and cost-effectiveness. By promoting proper waste disposal practices and fostering the development of sustainable construction materials, it becomes possible to mitigate adverse environmental impacts and foster economic growth in the construction sector.
