On a final note, one very controversial form of incineration that presently has been banned in the United States, but is used in Europe is ocean incineration. For this,two incinerators are mounted on a huge ship that carries the wastes out to the middle of the ocean and burns them out there.the ideal wastes for this kind of disposal are toxic and hazardous wastes such as chlorinated matter, pcb's,and organometallics. Ocean incineration is perfect for these wastes because the acids produced can be neutralized by the huge buffering capacity of the ocean. This eliminates the need for scrubbers and other secondary treatment to detoxify the combustion products and make them more environmentally acceptable
