Although the word “scrap” carries a pejorative charge, its use results in a steel of strong quality and valued in the market.

Sao Paulo, April 2022 – There are two relatively common ways of producing steel: by combining iron ore and coal or by recycling steel scrap. It is estimated that approximately 30% of the steel produced in Brazil comes from recycling. Steel is one of the few materials that can be infinitely recyclable without any loss of quality, according to industry experts.

Although the word “scrap” may suggest something pejorative, the steel from this recycling has a high added value, according to Açovisa's marketing manager, Giovani Marques da Costa. “Scrap is highly valued and coveted as a raw material”.

Figures from the International Iron and Steel Institute indicate that 630 million tons of the product are recycled annually. And Brazil has presented itself as one of the global leaders in recycling. The non-profit association Prolata alone recycled 55,090 tons of steel cans in 2021 - for example - which represents an increase of 141% compared to 2020. Most of these cans were recycled in the South, Southeast and Northeast regions: 28, 16 and 8 thousand tons of post-consumer steel cans, respectively. Paraná is the state that recycled the most.


The process begins with the separation of scrap in the selective collection of waste, this organization can be manual or electromagnetic. The scrap is then pressed into bales to facilitate and optimize transport to the steel mills, where it is subjected to high temperatures in electric ovens or to oxygen up to 1500º. At this temperature, the steel reaches its melting point, reaching the liquid state and being able to be molded into billets or metal plates and then formed into sheets, profiles and steel bars.

It is considered a fast process that reduces environmental impacts. In recycling, electricity consumption is 80% lower, there is also savings in the use of water, also because there is no ore extraction process. In addition, each ton of steel represents savings of 1,140 kilograms of iron ore. 

The final quality of recycled steel is also indicated by Costa:


Lamination is the process of reducing the thickness of a sheet, bar or metal profile by passing it between two or more rotating cylinders. And the process of rolling steel from scrap generates a higher quality product.

Mechanical properties

“When we talk about mechanical properties, we talk about elasticity, hardness, fatigue and tensile strength, for example, and these characteristics of scrap steel are usually more positive than common steel.”
