SHIPBOARD POLLUTION CONTROL: U.S. Navy Compliance With MARPOL Annex V
removed from an incinerator with the ash may be classified as toxic and lead to higher fees at landfill areas. The committee has used the term “destruction” where the actual process is conversion of waste to ash and air emissions by chemical means. The recommendation for adoption of an integrated system implies environmentally responsible disposal of the ash and air emissions.
Navy ships already have holding tanks of considerable size that are employed for storage of waste liquids. It will require analysis beyond the scope of this report to decide whether these tanks are available and are large enough to support biological treatment of black water.
The committee proposes that the integrated systems approach based on incineration is an attractive option for Navy ships, particularly for new construction, and offers good prospects for keeping pace with regulations as they evolve. These systems are commercially available in various sizes from manufacturers with extensive marine experience.
