Why is it important to recycle steel?

Metal recycling in Mexico

As it is an unalterable metal, its qualities, such as resistance, hardness or malleability, are not lost after the recycling processes, so it can be recycled as many times as desired. On the other hand, its magnetic properties facilitate the recovery process, since electromagnets can be used to separate it from other waste and recycle it properly.

On the other hand, it should be clarified that not only products made of this material are recycled, but also solid waste is processed to recover other metals, such as zinc. In addition, millions of tons of iron and steel are removed from the waste stream, due to its magnetic characteristics, making it easier to separate.

However, metals are one of the most polluting industrial inputs worldwide, not only because of their presence in the environment, but also because of all that their industrial processes imply in terms of waste, also known as “scrap”. Not to mention that the deposits (from which the metal is industrially extracted), are deposits of the same and are being gradually depleted.

Therefore, recycling metals such as steel, aluminum and iron considerably reduces environmental pollution, helping to reduce the consumption and exploitation of raw metals and energy consumption.

Clogged sewers represent an imminent risk of flooding during the rainy season, the accumulation of waste carried by the water causes the obstruction of the sewers, which is one of the main reasons for flooding every time there is a rainfall. In addition to remembering not to throw garbage in the streets.

Before the rainy season in Mexico, it is important to prevent flooding. Therefore, cleaning of drainage networks and clearing of sewers and canals in the city so that they are free of garbage, dirt and debris must be carried out so that rainwater can flow properly.

Benefits of recycling metals

At this stage ferrous metals are separated from other materials. This is made possible by the action of rotating magnetic drums in which separation is achieved by applying high-pressure air flows and electric current.

Finally, the molten steel is placed in molds that give it the shape of ingots or plates, and then rolled into sheets that will be used for the manufacture of products or for use in construction.

There is usually no waste in its production. As a recycled material, steel is nearly 100% recycled. This is due to its magnetic and induction capacity, characteristics that make it easy and inexpensive to collect.

Even products that are improperly discarded have the possibility of entering the recycling process when they reach incinerators, landfills and plants that work with organic waste. This is thanks to the fact that in many of these sites, there is equipment with electromagnets capable of extracting steel from other waste and thus recycling it.

As it is an unalterable metal, its qualities, such as strength, hardness or malleability, are not lost after the recycling processes, so it can be recycled as many times as desired. On the other hand, its magnetic properties facilitate the recovery process, since electromagnets can be used to separate it from other waste and recycle it properly.
