Abstract
Marine and river sediments have been subject to urban, industrial, agricultural and various anthropogenic contaminations. High concentration of nutrients and pollutants are often found, resulting in sticky sediment. One of the common practices to deal with the sediment in Hong Kong is regular dredging and followed up either marine dumping or landfill disposal depending on the contamination level of the sediment. Recycling sediment is not a common way, not until recent years. In view of the possible marine contamination and scarcity of land for landfill, beneficial reuse of dredged sediment is encouraged as a sustainable alternative in Hong Kong. For feasible engineering applications, on-site application of sediment means the saving transportation and disposal costs.
