Incinerators on board our ships are used to reduce the volume and weight of wastes that must be stored on board for landing, particularly those which cannot easily be reused or recycled. Thes use of incinerators saves lanfill space and prevents the build up of material onboard that could become the breeding ground for insects, rodents and other vermin.
Ash is the waste product that remains. To ensure that only those materials which are suitable for incineration reach the modern units on board, these is extensive waste separation. It begins with cabin stewards, waiters, and other crew who provide service. Then, in the garbage room, each bag of trash is again sorted before it goes down the chute to remove items which can be recycled or which could cause the ash to be hazardous. Special attention is placed on the removal of batteries from the incinerator waste stream, since these can-and should be-recycled. In general. source segregation for waste streams is a key component of onboard waste management and is incorporated into the waste management manual required by MARPOL. Waste management for onboard waste streams include the following: source reduction, minimization. recycling, collection. processing and discharge ashore. This allows the incinerator to be used primarily for food waste, cardboard, trash and wood. These waste management strategies are an important component of the Save the Waves program, and part of the training of each crew member.
Under US and international law, ash may be discharged at sea outside of 12 nautical miles. However, company policy is Above Beyond Compliance, with ash being landed for disposal.
