{{Main|Ship breaking}}
The hulls of ships, with any usable equipment salvaged and removed, can be broken up to provide scrap steel. For a time countries in south Asia carried out most shipbreaking, often using manual methods that were hazardous to workers and the environment. International regulations now dictate the treatment of old ships as sources of hazardous waste, so shipbreaking has returned to ports in more developed countries. In 2013, about 29 million tons of scrap steel were recovered from broken ships. Some of the scrap can be reheated and rolled to make products such as concrete reinforcing bars, or the scrap may be melted to make new steel.
