Talking about management firstly means to qualify sediments in the correct way: are they waste or freely manageable materials? The answer is not simple and, being aware of that, the Italian legislator repeatedly intervened, from 2006 to 2012, with laws and regulations in order to offer legal certainties to the interested parties.
During the latter part of the 20th century it became clear that another approach should be found for handling contaminated dredged material. Up to then it was common practise to dispose dredged material at sea or use it to raise the land or as fertilizer on land.
Good practice regarding the management of aquatic disposal of dredged material based on the Dredged Material Assessment Framework of the London Convention.
