Finding a win-win destinationĬontractors and clients now focus on finding uses for dredged material and for coordinating the supply of dredged material with a concurrent demand. Since 90 percent of dredged material is clean, use options can usually be found if all parties think about this during the planning of the project. When a use purpose is not an option, disposal alternatives must be considered and their destination on land or at sea may become controversial. When dredged material has a purpose, it can be used, for instance, for environmental improvements, giving the material added value and creating a win-win situation. Over the last few decades, however, research and experience have shown that dredged material can be reused and is not inevitably a waste to be disposed. The destination of this dredged material is often one of the greatest challenges facing a dredging project. Worldwide millions of cubic metres of material are removed each year from ports, harbours and waterways in order to optimise navigation, remediation and flood management.
