Proposal of industrialization process of dredged sediments

Abstract

Our study will focus on life cycle assessment (LCA) of dredged sediments in its environment from sediment extraction to waste treatment. This tool is part of an environmental management approach, to compare the environmental loads of the different stages of the life cycle of the same product and to deduce which stage of the scenario is the most polluting in environmental terms. Optimize the modeling of industrialization process of dredged sediments using the SimaPro 8.2.3 software to propose a model that is the most respectful of the environment. We will focus on the environmental impacts; we will try to propose the most environmentally friendly scenario to exploit these dredged sediments in the field of building construction.

L'effet de l'incorporation des sédiments calcinés et de la perlite comme remplacement partiel du ciment sur le comportement des mortiers

“…Des recherches ont été récemment menées sur l'utilisation des sédiments dragués des barrages dans divers domaines du génie civil. Ces études ont porté sur la caractérisation physico-chimique, mécanique (Belas et al, 2009) (Kazi Aoual-Benslafa et al, 2014 (Rachid et al, 2018) (Hadj Sadok et al, 2019) (Hadj Sadok, 2019 (Hadj Sadok et al, 2022) (Hadj Sadok et al, 2024 et la durabilité (Skibsted & Snellings, 2019) (Safer et al, 2018) (Fatima et al, 2018) révélant le potentiel d'utilisation de ces sédiments comme matières premières (Safhi et al, 2020). Dans une étude de (Hadj Sadok et al, 2019), un modèle d'industrialisation de ces sédiments a été proposé basé sur une analyse de cycle de vie.…”

Flash-Calcined Sediments for Zinc Adsorption

“…Snellings et al [27], for instance, proposed a thorough characterization (physicochemical and pozzolanic activity) of fine-grained sediments before assessing the behaviour of cement blends [28] made with calcination products. The recycling of calcination products is also considered during the conception of new types of concrete [29,30]. This valorization option faces, nevertheless, notable mechanical consistency issues [31] that hinder field application considerations.…”
