A method for treating materials dredged from a waterway, such as a harbor or channel, and forming a mixture suitable for beneficial re-use as structural fill. The dredged materials (28) may be placed in a treatment vessel (26) which transports the dredged materials (28) through a plurality of processing stages including a dewatering stage, a debris removal stage, a fixation, stabilization and solidification stage, a curing stage, and an offloading stage. The fixation, stabilization and solidification stage involves adding a cement type additive such as Portland Cement along with other additives which stabilize the dredged materials by chemical fixation and solidification to form the structural fill.

[ What is claimed is:] [1.]1. A method for producing a structural fill material comprising the steps of:obtaining a dredged material;depositing the dredged material into a containment receptacle;removing free water from the dredged material and the containment receptacle;creating an additive slurry in a mixing container;pumping the additive slurry from the mixing container to a mixing assembly disposed within the containment receptacle;mixing the additive slurry into the dredged material to form a substantially homogenous mixture; and,curing the substantially homogenous mixture in the containment receptacle, thereby producing a structural fill material and reducing particulate emissions.
