Worldwide metal production is ascertained directly through ore deposits from mining, smelting, and refining. What are secondary metals? They are metals discarded through industrial and manufacturing operations or as commercial products that are now obsolete. The benefit that recycling provides is that we return these waste materials back into the general manufacturing so they can be used for the production of new metal products, thus saving costs and making things more efficient in general. The secondary metals industry is involved in all aspects of this process, from locating scrap, to getting it to a recycle facility and then re-using the material for new metal-based products.
What's the rationale for determining if scrap metal is worth recovering? Its potential for profit. In terms of the basic factors that determine if a particular metal should be recycled, the following areas are looked at:
The advent of the industrial revolution in the late 19 th and early 20 th centuries fueled the consumption of metals significantly. During the 20th century, this trend continued and grew exponentially. By the 1980's, the annual production of metals worldwide was a hundred times what it was in the 1880's. Naturally, this incredible rise in need for metals and the production of metal-based products has led many people to question if there is enough metal reserves in the world to keep up with demand. Is it sustainable? Is there an unending amount of metals in the earth? No, on both accounts. Scrap metal recycling is a natural part of the chain of use. Metal reserves are found, they are made into a usable form, a product is manufactured from it, the product is used, discarded, and then the metal is used again. It just makes ecological sense
