Review of Life Cycle Assessment Studies of Sediment Stabilisation/Solidification Treatment

The aim of this paper is to review life cycle assessment studies on the stabilisation/solidification treatment of freshwater or marine sediments.First, the life cycle assessment studies on stabilisation/solidification treatment of sediments were reviewed on the Web of Science platform and eleven studies were selected.Secondly, the standardised phases of life cycle assessment were used as review criteria: Goal and Scope, Inventory Analysis, Life Cycle Impact Assessment, and Interpretation.The results of the review systematically showed information about the life cycle assessment phases and provided the similarities and differences.All studies reviewed had system boundaries from cradle to gate, but six studies did not include sediment dredging in the upstream life cycle stages.Ten of eleven studies used life cycle inventory databases to model background processes, and six studies reported the names of the datasets used.For the life cycle impact assessment methods, all studies used the CML, ReCiPe, and IMPACT 2002+ methods.In the interpretation phase, all studies included hotspot, contribution and scenario analyses, while sensitivity and uncertainty analyses were used in six out of eleven studies.The results of the review provide information that can be a good starting point for new research in this area.
