Review of the current situation of coastal ecological engineering using dredged marine sediments and prospects for potential application in China

Abstract

Dredged marine sediments, which are traditionally discarded by open sea disposal, have historically been one of

Recent Progress on Ex Situ Remediation Technology and Resource Utilization for Heavy Metal Contaminated Sediment

“…Dredged sediment is beneficial when used in coastal/wetlands restoration and marsh creation projects [ 18 , 19 , 142 , 143 , 144 , 145 ]. In these processes, sediments provide substrates that nourish habitats and promote the recovery of coastal flora and fauna [ 146 ]. On one hand, sediment can be mechanically or hydraulically dredged and transported by pipelines and distributed in open water areas to replenish nutrients in the marshes [ 18 , 19 ].…”

Evaluation of Chemical Properties of Dredged Materials, Paranagua Port, Brazil, According to Dredging Legislation CONAMA 454/2012

“…Beneficial use includes a variety of options that utilize the material for some productive purpose, such as habitat restoration, agriculture, landfill cover, shoreline stabilization or beach nourishment [3]. According to Huang Huamei et al [4] combination of dredged marine materials treatment with coastal ecological engineering also has potential opportunities to guarantee the sustainable development of the marine industry.…”
