Processing

Scrap metal originates both in business and residential environments. Typically a "scrapper" will advertise their services to conveniently remove scrap metal for people who don't need it. Scrap is often taken to a

is often used to recycle items containing a variety of other materials in combination with steel. Examples are automobiles and white goods such as refrigerators, stoves, clothes washers, etc. These items are labor-intensive to manually sort things like plastic, copper, aluminum, and brass. By shredding into relatively small pieces, the steel can easily be separated out magnetically. The non-ferrous waste stream requires other techniques to sort. In contrast to wrecking yards, scrapyards typically sell everything by weight, instead of by item. To the scrapyard, the primary value of the scrap is what the smelter will give them for it, rather than the value of whatever shape the metal may be in. An auto wrecker, on the other hand, would price exactly the same scrap based on what the item does, regardless of what it weighs. Typically, if a wrecker cannot sell something above the value of the metal in it, they would then take it to the scrapyard and sell it by weight. Equipment containing parts of various metals can often be purchased at a price below that of either of the metals, due to saving the scrapyard the labor of separating the metals before shipping them to be recycled. Thieves sometimes sell stolen items to scrapyards. Copper pipes and wiring, bronze monuments and aluminium siding have all been targets of
metal theft Metal theft is "the theft of items for the value of their constituent metals". It usually increases when worldwide prices for scrap metal rise, as has happened dramatically due to rapid industrialization in India and China. Apart from precious m ...

Resources

Scrap prices may vary markedly over time and in different locations. Prices are often negotiated among buyers and sellers directly or indirectly over the Internet. Prices displayed as the market prices are not the prices that recyclers will see at the scrap yards. Other prices are ranges or older and not updated frequently. Some scrap yards' websites have updated scrap prices. In the US, scrap prices are reported in a handful of publications, including ''

'', based on confirmed sales as well as reference sites such as Scrap Metal Prices and Auctions. Non-US domiciled publications, such as ''The Steel Index'', also report on the US scrap price, which has become increasingly important to global export markets. Scrap yards directories are also used by recyclers to find facilities in the US and Canada, allowing users to get in contact with yards. With resources online for recyclers to look at for scrapping tips, like web sites, blogs, and search engines, scrapping is often referred to as a hands and labor-intensive job. Taking apart and separating metals is important to making more money on scrap, for tips like using a magnet to determine ferrous and non-ferrous materials, that can help recyclers make more money on their metal recycling. When a magnet sticks to the metal, it will be a ferrous material, like steel or iron. This is usually a less expensive item that is recycled but usually is recycled in larger quantities of thousands of pounds. Non-ferrous metals like copper, aluminum, and brass do not stick to a magnet. Some cheaper grades of stainless steel are magnetic, other grades are not. These items are higher priced commodities for metal recycling and are important to separate when recycling them. The prices of non-ferrous metals also tend to fluctuate more than ferrous metals so it is important for recyclers to pay attention to these sources and the overall markets.


Hazards

Great potential exists in the scrap metal industry for accidents in which a hazardous material present in scrap causes death, injury, or environmental damage. A classic example is radioactivity in scrap; the

Metal recycling industry

The metal recycling industry encompasses a wide range of metals. The more frequently recycled metals are scrap steel, iron (ISS), lead, aluminium, copper, stainless steel and zinc. There are two main categories of metals: ferrous and non-ferrous. Metals which contain iron in them are known as ''ferrous''. Metals without iron are ''non-ferrous''. * Common non-ferrous metals are copper, brass, aluminum, zinc, magnesium, tin, nickel, and lead. *Usable

Description

In the United States, steel containers, cans, automobiles, appliances, and construction materials contribute the greatest weight of recycled materials. For example, in 2008, more than 97% of structural steel and 106% of automobiles were recycled, comparing the current steel consumption for each industry with the amount of recycled steel being produced (the
late 2000s recession The Great Recession was a period of marked general decline, i.e. a recession, observed in national economies globally that occurred from late 2007 into 2009. The scale and timing of the recession varied from country to country (see map). At t ...
and the associated sharp decline in automobile production in the US explains the over-100% calculation). A typical appliance is about 75% steel by weight and automobiles are about 65% steel and iron. The steel industry has been actively recycling for more than 150 years, in large part because it is economically advantageous to do so. It is cheaper to recycle steel than to mine iron ore and manipulate it through the production process to form new steel. Steel does not lose any of its inherent physical properties during the recycling process, and has drastically reduced energy and material requirements compared with refinement from iron ore. The energy saved by recycling reduces the annual energy consumption of the industry by about 75%, which is enough to power eighteen million homes for one year. According to the

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 ship breaking, often using manual methods that were hazardous to workers and the environment. International regulations now dictate treatment of old ships as sources of hazardous waste, so ship breaking has returned to ports in more developed countries. In 2013, about 29 million tons of scrap steel was 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.
