Currently, the concepts of sustainability and recycling have gained special relevance in recent years, just as the demand for metals has increased considerably. Given this scenario, the following question arises: Is extraction the only solution to ensure supply? The answer is no. Metal recovery is the ideal alternative to mining, ensuring supply and reducing the environmental and economic impact.
What is metal recovery?
Metal recovery is a fundamental process in the field of sustainability and environmental management. It consists of collecting, sorting and recycling metallic materials from various wastes. This process seeks to recover the metals that make up these wastes in order to convert them into new products or reintegrate them into industrial processes while maintaining their properties and promoting circularity.
Benefits of metal recovery
There are many benefits of metal recycling, since it is not only about the use of the material itself, but also about the benefits that its correct recycling brings to the environment, in addition to numerous economic and social advantages:
Improved air quality
By recycling metals instead of manufacturing them from scratch, the need to go through industrial processes that generate greenhouse gases is reduced. Recycling aluminum, in fact, results in reduced emissions of 9.8 tons of CO₂ and 64 kilograms of sulfur dioxide while reducing the energy and material costs associated with conventional manufacturing.
Reduction of mining
Mining is an intensive raw material extraction operation that generates a lot of waste such as rocks and soil, which contain precious metals. Every year, 5 tons of mining waste are formed and this waste represents a serious environmental threat, as it contaminates soil and water and contributes to biodiversity loss. Recovering metals from mining waste reduces the amount of material to be stored in landfills or incinerators, reducing the environmental footprint.
Decrease in waste destined for incineration
Burning waste generates carbon dioxide and releases toxic compounds such as dioxins and furans into the air, threatening human health and the environment. Recycling reduces the amount of waste that is incinerated, helping to reduce negative impacts and promoting a cleaner, healthier environment.
Improved water pollution
Metal waste can contain toxic compounds that threaten aquatic life and can affect drinking water quality. By recovering and recycling these metals, contaminants are prevented from entering the aquatic environment, protecting ecosystems and providing clean, safe water for people.
Avoid extraction from non-renewable sources
Most metals are extracted from non-renewable sources. This extraction can have serious environmental consequences, such as soil erosion, deforestation and loss of biodiversity. Recycling metals reduces the overexploitation of non-renewable resources and the constant need to extract new materials from the earth, conserving natural resources and protecting fragile ecosystems.
What is done with the metal recovered from waste?
Metal recovery is a widely used recycling technique nowadays due to the versatility and durability of metals, which make them an indispensable material in all types of industries and applications.
The most recycled type of metal today is steel. Steel is very malleable, so it can be used to create a wide variety of shapes depending on its carbon content. In this way we can use reused steel mainly in building structures, automobile manufacturing, household appliances and industrial machinery, among others. As for other types of metals currently reused, iron is widely used in the construction, automotive and shipbuilding industries due to its highly magnetic properties. Likewise, recycled aluminum has become another invaluable resource due to its lightness and strength, properties needed in the aerospace industry, industrial components and packaging. Finally, copper is also especially reused in the manufacture of wire due to its excellent electrical conductivity and resistance to corrosion.
As we can see, metals have the capacity to be recycled several times without losing their qualities, which makes them important elements that promote the circular economy, changing the traditional concept of “waste” to “zero waste”, favoring efficiency and sustainability.
At Sircat we offer a metal recovery service to identify, separate and efficiently recycle all reusable metals from waste, thus contributing to the creation of a circular economy.
