The steel recycling industry consists of a variety of procedures, but in most cases the common method involves reclaiming scrap steel during secondary processing, such as industrial roll recycling or scrap processing. This process can take several forms, with some procedures being more environmentally-friendly than others. Some recycling programs are not as eco-friendly as others.
Structural steel recycling is one method that is considered to be environmentally responsible. Since this process uses steel recycled from demolition sites or buildings torn down for reconstruction, it reduces contamination of surrounding land and decreases the waste of natural resources such as coal and petroleum. This secondary processing is done primarily at the demolition site to reduce the amount of debris that must be disposed of, and therefore the amount of waste and pollution created. The recycled metal is then used to construct new structures.
In another method of structural steel recycling, aluminum is melted and poured into a steel mold, after which it is cooled and hardened. After forming, the cooled aluminum is then used to make new steel products, such as columns, beams, and plates. This process is known as binding. After a series of metal parts are made by using the bladed steel, these metal parts are sold to manufacturers who make new steel products. Aluminum sheeting is also sometimes used to make frames for steel products.
During the secondary processing stage of steel recycling, scrap steel is first converted to ferrous scrap, then nickel steel and then zinc-coated steel. This process also converts unwanted non-ferrous metal into steel that can be used in steel production. The steel scrap, along with the other recycled materials, is then taken to a steel recycling institute. At the institute, the scrap and leftover steel are separated out into useful components for manufacturing processes.
Although scrap metal recycling programs benefit steel producers, they also have an impact on the environment. Since most scrap metal recycling programs are done through the employment of trucks, some of the materials are sent in large quantities to landfills, which cause pollution. Also, because of the large amount of recycled scrap metal, the price of the raw material needed to make steel is higher.
A major benefit of recycled material is its contribution to greenhouse gas emissions. Steel that is recycled releases fewer greenhouse gases than the raw material that is used to create it. By recycling scrap material, we are helping to reduce the amount of greenhouse gas emissions that result from the burning of fossil fuels. However, in order to fully benefit from this type of recycling, it is essential that the recycled material is correctly used. Otherwise, the resulting steel products will be ineffective as steel.
