Abstract

Dredging activities are necessary to maintain the navigation depth of harbors and channels. Additionally,
dredging can prevent the loss of water bodies. A large amount of extracted sediments is produced around the
world. Removed material is widely disposed at open seas or landfills. Much of the dredged material is polluted
and is classified as unsuitable for open-sea disposal. In Sweden, many dredging activities are taking place
nowadays like that in Oskarshamn harbor, Inre harbor Norrköping municipality and Malmfjärden bay in
Kalmar. In this review, the potential of phytoremediation as a treatment method is discussed with focus on
suggested methods for reusing the treated sediments. Recycling or reusing of dredged and treated sediments
will preserve Earth natural resources as well as reduce diffusion of contaminants to the environment.
