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.

Phytoremediation is a process which utilizes plants to remove contaminants from the environment. It is the latest alternative to treatment technique that needs to identify potential plants and their ability to resist toxicity of contaminants before a full scale system can be installed to ensure that the remedy is effective by the selected plants. The aim of this study is to evaluate the ability of two native plants in Malaysia, Ludwigia octovolvis and Phragmites karka, to survive when exposed to real crude oil sludge. The experiment was performed in a greenhouse for 15 days. The observation was made three times a week. The plants were also watered using tap water to ensure the plants could grow. After 15 days of observation, the two plant species had shown that they could grow and survive in pots with 100% of crude oil sludge. From this preliminary test, L. octovolvis and P. karka showed their initial ability to treat sand contaminated with crude oil sludge. As a conclusion, both native plants have the potential in the phytoremediation process of hydrocarbon and will be used in future prolonged phytoremediation of crude oil sludge.
