Ship recycling contributes to sustainable development and is the environmentally friendly way of disposing of ships with virtually every part of the hull, machinery, equipment, fittings and even furniture being re-used. However, while the principle of ship recycling is a sound one, the reported status of working practices and environmental standards in recycling facilities often leaves much to be desired. Such growing concerns about environmental safety, health and welfare matters in the ship recycling industry have resulted in a growing belief that an international instrument to regulate the ship recycling process is urgently needed.

Having become aware of the need to reduce the environmental, occupational health and safety risks related to ship recycling, as well as the need to secure the smooth withdrawal of ships that have reached the end of their operating lives, the International Maritime Organization (IMO) has taken action to develop a realistic and effective solution to the problem of ship recycling, which will take into account the particular characteristics of international maritime transport and the economic realities.

A.Ship recycling is sustainable

B.Ship recycling is very friendly to our environment

C.Ship recycling is the best way to dispose the machinery, equipment, fittings and even furniture on board

D.Ship recycling brings many problems concerning environmental safety, health and______occupational safety
