Incineration on board outside of an incinerator is prohibited, except that sewage sludge and sludge oil from oil separators may be burned in auxiliary power plants and boilers when the ship is not in ports, harbors and estuaries.

PVC burning
The burning of PVC (polyvinyl chloride) is prohibited unless the ship has an incinerator type approved in accordance with resolutions MEPC 59(33) or MEPC 76(40).
Control of combustion flue gas outlet temperature should be required at all times and waste should not be supplied to a ship's continuous feed incinerator when the temperature is below the minimum permissible temperature of 850°C. When batch loading shipboard incinerators, the installation must be designed in such a way that the temperature in the combustion chamber reaches 600°C within 5 minutes after start-up. It is necessary to ensure the operability of the system for monitoring the temperature of flue gases exiting waste incinerators (offshore employment sites).
In all cases where burning is carried out, proper and accurate entries must be made in the oil and waste books.
All incinerators installed on or after 1 January 2000 must be type approved in accordance with MEPC Resolution 76(40), which contains the IMO Standard Specification for Shipboard Incinerators. required.
