EXPLORING THE POTENTIAL OF SEDIMENT BENEFICIAL USE: ECONOMIC VIABILITY AND ENVIRONMENTAL SUSTAINABILITY

Over the past few decades, sediment has gained recognition as a challenging resource, attributed to its potentially harmful effects and the substantial volumes found within aquatic environments. Although, traditionally viewed as a waste product of dredging operations, sediment holds immense potential for beneficial use across multiple sectors, offering economic benefits while addressing environmental concerns. The utilization of sediment as a construction material constituent offers a sustainable alternative to virgin resources, reducing extraction pressures and lowering production costs. However, the economic feasibility of sediment beneficial use hinges on several critical factors. The quality of sediment, including its contamination levels and necessitates appropriate treatment measures. Process of solidification and stabilisation uses binders to physically strengthen the sediment for structural engineering use while also reducing the mobility and solubility of the contaminant. Different waste materials can be used as additional binders, in the remediation process. Their effectiveness is evaluated based on the microstructural properties and chemical integrity of produced aggregates. Transportation costs and regulatory frameworks further shape the economic landscape, impacting project viability and scalability. Market demand for recycled materials and technological advancements in sediment processing play pivotal roles in unlocking its economic potential. This research underscore the importance of a comprehensive understanding of sediment management strategies, balancing economic considerations with environmental sustainability goals. Through innovative approaches and collaborative efforts, sediment beneficial use can emerge as a cornerstone of circular economy principles, driving economic growth while preserving and enhancing natural ecosystems.
