Scrap
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes. Scrap recycling is important for creating a more sustainable economy or creating a circular economy, using significantly less energy and having far less environmental impact than producing metal from ore. Metal recycling, especially of structural steel, ships, used manufactured goods, such as vehicles and white goods, is a major industrial activity with complex networks of wrecking yards, sorting facilities and recycling plants. Processing Scrap metal originates both in business and residential environments. Typically a "scra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Scrap Metal
Radioactive scrap metal is created when radioactive material enters the metal recycling process and contaminates scrap metal. Overview A "lost source accident" occurs when a radioactive object is lost or stolen. Such objects may appear in the scrap metal industry if people mistake them for harmless bits of metal. The International Atomic Energy Agency has provided guides for scrap metal collectors on what a sealed source might look like. The best known example of this type of event is the Goiânia accident, in Brazil. While some lost-source accidents have not involved the scrap metal industry, they are good examples of the likely scale and scope of a lost-source accident. For example, the Red Army left sources behind in Didi Lilo, Georgia Training Detachment of Frontier Troops, Lilo]. Another case occurred at Yanango where an 192Ir radiography source was lost and at Gilan, Iran a radiography source harmed a welder. Radioactive sources have a wide range of uses in medicin ...

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 metals like gold and silver, the metals most commonly stolen are non-ferrous metals such as copper, aluminium, brass, and bronze. However, even cast iron and steel are seeing higher rates of theft due to increased scrap metal prices. One defining characteristic of metal theft is the motivation. Whereas other items are generally stolen for their extrinsic value, items involved in metal theft are stolen for their intrinsic value as raw material or commodities. Thefts often have negative consequences much greater than the value of the metal stolen, such as the destruction of valuable statues, power interruptions, and the disruption of railway traffic. Items often stolen Anything made of metal has value as scrap metal, and can be stolen: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts Part, parts or PART may refer to: People *Armi Pärt (born 1991), Estonian handballer * Arvo Pärt (born 1935), Estonian classical composer *Brian Part (born 1962), American child actor *Dealtry Charles Part (1882–1961), sheriff (1926–1927) a ..., which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycling, recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking i ...

Wrecking Yard
A wrecking yard ( Australian, New Zealand, and Canadian English), scrapyard ( Irish, British and New Zealand English) or junkyard (American English) is the location of a business in dismantling where wrecked or decommissioned vehicles are brought, their usable parts are sold for use in operating vehicles, while the unusable metal parts, known as scrap metal parts, are sold to metal-recycling companies. Other terms include wreck yard, wrecker's yard, salvage yard, breaker's yard, dismantler and scrapheap. In the United Kingdom, car salvage yards are known as car breakers, while motorcycle salvage yards are known as bike breakers. In Australia, they are often referred to as 'Wreckers'. Types of wreck yards The most common type of wreck yards are automobile wreck yards, but junkyards for motorcycles, bicycles, trucks, buses, small airplanes and boats or trains exist too. Scrapyard A scrapyard is a recycling center that buys and sells scrap metal. Scrapyards are effectively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrap Metal Shredder
A scrap metal shredder, also sometimes referred to as a metal scrap shredder, is a machine used for reducing the size of scrap metal. Scrap metal shredders come in many different variations and sizes. Applications Some examples of scrap metal materials that are commonly shredded are: Car crushers are large machines that turn a car into a large bucket of scrap steel and the rest of the car into non-ferrous materials, plastics and waste called automotive shredder residue. The glass, fabric, plastic, and all other non-ferrous materials are separated by eddy current magnets in place of heavy media separation. The non-ferrous materials may be referred to as "zorba". Often the profit from the non-ferrous materials covers the operating cost for the shredder. When a metal shredder starts, the material enters into the tear box through the feeding system. The tear blade is loaded on the box. The material is torn into small pieces through the tear, extrusion and shear of the tear blade ...

Goiânia Accident
The Goiânia accident was a radioactive contamination accident that occurred on September 13, 1987, in Goiânia, Goiás, Brazil, after a forgotten radiotherapy source was stolen from an abandoned hospital site in the city. It was subsequently handled by many people, resulting in four deaths. About 112,000 people were examined for radioactive contamination and 249 of them were found to have been contaminated. In the consequent cleanup operation, topsoil had to be removed from several sites, and several houses were demolished. All the objects from within those houses, including personal possessions, were seized and incinerated. ''Time'' magazine has identified the accident as one of the world's "worst nuclear disasters" and the International Atomic Energy Agency (IAEA) called it "one of the world's worst radiological incidents". Description of the source The radiation source in the Goiânia accident was a small capsule containing about of highly radioactive caesium c ...

Recycling
Recycling is the process of converting waste materials into new materials and objects. The Energy recycling, recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling). Recycling is a key component of modern waste reduction and is the third component of the "Waste minimisation, Reduce, Reuse, and Recycle" waste hierarchy. It promotes environmental sustainability by removing raw material input and redirecting waste output in the economic system. There are some International Organization for Standardization, ISO standards related t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayapuri Radiological Accident
Mayapuri is an industrial locality in West Delhi. It used to be a major hub of heavy metal and small scale industries, but following recent government sanctions, most of the heavy metal industries moved out. The place is now a combination of residential area, light metal factories, scrap markets, and automobile service stations. In 2010, a major radiation accident took place in the scrap yards of Mayapuri. There are some famous landmarks in the area like the Food Corporation of India, Metal Forging and Deen Dayal Upadhyay Hospital. The area is connected with Delhi Metro by Mayapuri station. Mayapuri is also one of the major bus terminals for the Delhi Transport Corporation (DTC). 2010 Mayapuri radiological accident In the early April of 2010, Mayapuri was affected by a serious radiological accident. An AECL Gammacell 220 research irradiator owned by Delhi University since 1968, but unused since 1985, was negligently sold at an auction to a scrap metal dealer in Mayapuri ...

Vehicle Recycling
__NOTOC__ Vehicle recycling is the dismantling of vehicles for spare parts. At the end of their useful life, vehicles have value as a source of spare parts and this has created a vehicle dismantling industry. The industry has various names for its business outlets including wrecking yard, auto dismantling yard, car spare parts supplier, and recently, auto or vehicle recycling. Vehicle recycling has always occurred to some degree but in recent years manufacturers have become involved in the process. A car crusher is often used to reduce the size of the scrapped vehicle for transportation to a steel mill. Approximately 12-15 million vehicles reach the end of their use each year in just the United States alone. These automobiles, although out of commission, can still have a purpose by giving back the metal and other recyclable materials that are contained in them. The vehicles are shredded and the metal content is recovered for recycling, while in many areas, the rest is further ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both aluminium and copper, having a biological cleanability comparable to glass. I ...

Waste
Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes ( feces and urine) and surface runoff), radioactive waste, and others. Definitions What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person. Though waste is a physical object, its generation is a physical and psychological process. The definitions used by various agencies are as below. United Nations Environment Program According to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes ...

Metal
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the '' metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polythiazyl, polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials re ...
