Scrap metal may not look so glamorous, but scrap metal recycling is a multi-billion industry. All metals available today can be recycled repeatedly without causing any alteration to their properties. Even though there are very many different metals used to make various products, not all of them are recycled in the same amount. There are many factors that make some metals to be recycled more than others. When one needs Scrap Metal St Louis Offers the perfect location to visit.
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.
A number of reasons have necessitated metal recycling, with the aim of aiding in cleaning the environment being one of them. Scrap metals are known to cause major accidents and rendering a place ugly. The scrap may also contaminate the environment through massive pollution. As such, by recycling, the environment becomes less polluted and safer.
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 processing stage involves shredding the metals to achieve a high surface area to volume ration. This is important because it reduces the amount of energy needed to melt the metals afterwards. As a result, energy savings in a recycling operation usually reach more than 75 percent. At the same time savings on raw materials reaches 90 percent. Aluminum is usually converted into small sheets while steel is converted into steel blocks during processing.
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.
