Contaminated (TPHs and heavy metals) dredged sediments from Livorno port (Italy) were biological treated using plants and earthworms. Sediments presented an asphyctic physical structure owing to the silt-clay granulometric composition, a high salty level and a low organic content. A meso-scale experiment was done utilising three different bioremediation treatments: a) plants (Paspalum vaginatum and Tamarix gallica), b) earthworms (Eisenia foetida) and c) plant-earthworms combination. After one year, a suitable habitat for plants and earthworms was created due to the biochemical activation of the matrix, observing also a reduction of the organic and inorganic contaminants.
