This review investigates the potential of waste paper sludge (WPS) as a partial replacement for cement in concrete, addressing environmental and resource efficiency issues. WPS, a by-product of paper manufacturing, is usually disposed of through landfill or incineration, methods with harmful environmental impacts. Incorporating WPS into concrete offers a sustainable alternative, reducing cement use, carbon emissions, and waste. The study examines how varying WPS percentages affect concrete properties, including workability, compressive strength, tensile strength, and durability. The findings suggest that using WPS in concrete production can contribute to more sustainable construction practices by enhancing resource efficiency and mitigating environmental harm. It also identifies the research gaps, particularly in terms of workability, strength characteristics, and the lack of non-destructive testing methods such as Ultrasonic Pulse Velocity (UPV) and Rebound Hammer. The paper discusses the need for further research to develop experimental models for the optimal use of WPS in concrete mixes and its potential for improving concrete performance while contributing to sustainable construction practices.
