If ship repair is considered uneconomical then ship breaking is the last possible choice. Chopping a ship is a job of unpacking or chopping a used ship. The advantage of that choice is to get a scrap. While the ship equipment that is still functioning can be reused. Scrap is the remaining recycled material from manufacturing and consumption products, such as parts (spare parts) of vehicles, building materials, war equipment, and other materials. Unlike waste, scrap can have significant value / price. Scrap of ex-used ships other than ferrous metals, commonly referred to as scrap metal, is also non-ferrous metal, such as copper, brass, aluminum, zinc, magnesium, tin, nickel and tin.
Until the end of the 20th century, ship chopping work took place in port cities of industrialized nations such as Britain and the United States. Today, developing countries are beginning to do so, because labor costs are lower and environmental regulations are less stringent, especially about the disposal of toxic substances such as lead paint and asbestos. Before it was banned until the mid-1980s, asbestos was the majority material in shipbuilding.

Inevitably, the former ship breakers are running a business that is contradictory. He is an important scrap supplier as a raw material for steel mills. The scrap metal is recycled into a new iron product. The use of scrap for the manufacture of iron reduces greenhouse gas emissions, saving energy and reducing dependence on natural resources. Every ton of new steel made from ferrous metal scrap can save 1,115 kg of iron ore, 625 kg of coal and 53 kg of limestone.
According to a US Environmental Protection Agency study, using scrap recycling as a substitute for iron ore can generate 75% energy savings, 90% savings on raw materials used, 86% reduction in air pollution, 40% reduction in water use, 76% reduction water pollution and 97% reduction in mining waste.

In general, scrap raw materials take up to 70% of the need for production of iron-steel.
On the other hand, the activity of enumerating these vessels allows the release of large amounts of highly toxic materials into the general environment and causes serious health problems between ship breakers, local residents, and surrounding flora-fauna. Workers' protective equipment is missing or inadequate. As a result, cutting, sorting and removing high-risk metal scrap so that the costs incurred can be more expensive than the price of scrap metal itself.
In the future, it can not be denied that Indonesia, which aspires to be the maritime axis of the world, will surely face the bustle of maritime facilities. The abundance of natural wealth is a gift and very supportive. But a friendly environment would be a prerequisite as well as a goal. And we'll get to that situation.
