Despite scrap metal not appearing as stylish, the industry of scrap metal recycling exists as a multi-billion enterprise. Today, all available metals can repeatedly be recycled without their properties being altered. In spite of there being a wide variety of metals used in making various products, only some of them are recycled. A number of factors make the recycling of some metals to be done more compared to others. When in need of Scrap Metal St Louis should be visited.
Statistics collected by the AISI indicate that steel is the most recycled material in the world. AISI is the American Iron and Steel Institute. This institute monitors and governs the production, processing, consumption, and recycling of iron and steel in the US and the whole world. Besides steel, other metals that are highly recycled include aluminum, copper, gold, silver, and brass.
The recycling of metal is motivated by several reasons. One of the reasons is that it helps to clean up the environment. Scrap metal does not only make a place look ugly, it also poses a major cause of accidents. Such metals may also find their way into the environment and cause major pollution. Thus, by having them recycled, the environment is made safer and less polluted.
There is an economic aspect to the recycling process. Most often, one is paid for the job of metal collection for recycling. The scraps are sold per pound to a recycling operation. The metal one supplies to the operation is weighed and them payment is made as per the tonnage. This usually motivates collectors to collect more metals for a pay day. This activity makes a livelihood for some people in poor countries.
Recycling is composed of several processes that are done in a given sequence. These processes include collection, sorting, processing, melting, purification, solidification, and transportation in form of bars. Collection is usually done by various stakeholders including individuals and companies. There are scrap yards where people take the metals they have collected. Major sources of the metals in the US include farm equipment, consumer scrap, railroad tracks, and ships among others.
Sorting is done once the collection is finished. This allows removal of non-metallic materials. Magnets and sensors are used in the sorting process in automated recycling operations. With the use of magnets and sensors, metallic materials are separated from non-metallic materials more easily. Also, in this process, metals that are clean are separated from dirty ones.
The metals are then shredded to increase the ration of surface area to volume during the processing stage. The importance of this is to minimize the energy needed in melting the metals. The result of this can be seen in the significant reduction in the amount of energy needed in recycling operations. Usually, energy needs are cut by 75 percent. Similarly, raw materials are saved by up to 90 percent. In the processing stage, steel is turned into steel blocks and aluminum is turned into small sheets.
The process of melting is done inside a big furnace. Each metals is usually melted using a specific furnace. Thus, the furnace is designed in a special way to suit that metal. Melting of metals requires a significant amount of energy, which makes this operation energy-intensive. How long the metal stays in the furnace during melting depends largely on the type of metal.
