Section 4 Treatment of solid waste matter

4.1 General

4.1.1 Facilities are to be provided on board for the treatment and storage of all solid waste generated. In general, facilities are to be provided for the thermal destruction of solid waste on board to enable disposal of as much solid waste as possible when the ship is at sea.

4.1.2 Sufficient space is to be made available to store and secure all waste generated between sailing and next shore stop, or waste collection where there are no incineration facilities on board.

4.1.3 The storage facilities are to be sufficient in capacity for the storage of solid waste produced during the defined ship's missions and capability of any installed thermal destruction plant for solid waste disposal. This is to take into account voyages in special areas where disposal is prohibited.

4.1.4 The storage of solid waste is to be such that the waste is prevented from rotting, by provision of suitable cooling facilities where necessary. Alternatively, the waste may be packed such that no gases or odours are spread.

4.1.5 Independent and safe storage spaces are to be available for medical, sanitary, oil contaminated and other hazardous wastes to ensure that such wastes are kept separate from each other and other solid wastes.

4.1.6 Each storage space shall be provided with adequate ventilation capacity and insulated, where necessary. Cooling facilities to comply with Vol 2, Pt 11, Ch 3, 4.1 General 4.1.4 may also be required. All spaces used for storage of solid waste are to be provided with fire detection equipment, and shelving within storage facilities are to be arranged in a grid so as to enable access for fire-fighting purposes.

4.1.7 Consideration shall be given to the location of treatment and storage rooms, in terms of separation from accommodation and communal areas. Similarly, waste treatment and storage spaces are to be located so as to facilitate the convenient handling of waste on board the ship, and its transfer ashore.

4.1.8 Solid waste treatment plant, such as food waste pulpers, compactors and shredders, are to be suitable for their intended function. The capacity of the waste processing equipment is to be sufficient to process the specified amount of waste. Equipment for wastes treatment is not to produce toxic fumes, heavy smoke or excessive noise when functioning.

4.1.9 The arrangements in waste storage spaces are to allow easy access for cleaning. Drains in solid waste storage and treatment spaces are to be easy to clean and should prevent waste/dirt entering the system. In selecting deck coating and covering materials, consideration is to be given to ease of cleaning, and impact and corrosion protection. Sufficient space is to be available on all sides of waste treatment equipment to allow maintenance access.

4.1.10 When the ship is in harbour, all stored waste is to be normally disposed of ashore or retained on board when reception facilities are not available.
