Claim:
A method for treatment and disposal of contaminated drilling waste and contaminated sediments, said method comprising the following steps: step 1, providing material selected from the group consisting of: contaminated drilling waste and contaminated sediments, and separating the contaminated material into different fractions and separating the contaminated material for compatibility with at least one binder; step 2, grinding or crushing some fractions of the separated contaminated material from step 1 to a particle size less than 5 mm; step 3, mixing all the material from step 2 with at least one binder that is compatible with the separated contaminated material to form a stabilized mixture that is substantially immiscible with water, and all of the material from step 2 is less than 5 mm; step 4, transferring the stabilized mixture from step 3 through a fluid supply line extending from a drill rig to a disposal device placed in a benthic zone; and step 5, allowing the stabilized mixture from step 4 to cure in the disposal device.
