Regulations classify dredged material based on contaminant concentration, and when hazardous it requires treatment and landfilling, leaving much material underutilized. Plant nurseries rely heavily on peat, which is increasingly unsustainable, prompting interest in peat-free substitutes. This work frames phytoremediation as a sustainable route to improve sediment structure, nutrient availability, and pollutant stabilization, enabling contaminated dredged sediments to be repurposed as growing media.","cbCaijlgVGfB1Haj","https://ap.wps.com/l/cbCaijlgVGfB1Haj","pdf",1591523,4,1,"English","en","# Introduction\n## Sediment dredging and contamination\n## Regulatory classification and disposal constraints\n## Peat use in plant nurseries and sustainability concerns\n## Alternatives and limitations of peat substitutes\n## Phytoremediation as a management and reuse strategy\n## Characterization methods and research hypothesis","[{\"question\":\"Why are dredged sediments a disposal and reuse challenge in maritime ports?\",\"answer\":\"They often contain heavy metals and hydrocarbons from ship-related activities.
