Understand how steel recycling works in the industry
STEEL DAY BY DAY
Steel is among the most recyclable and recycled materials in the world. The industry encourages the collection and recycling of steel contained in products at end-of-life, employing it in the manufacture of new steel products without any loss of quality.
Thus, steel production from scrap reduces the consumption of non-renewable raw materials, saves energy and avoids the need to occupy areas for the disposal of obsolete products.

STEEL AND CIRCULAR ECONOMY
A new concept has been firmly integrated into the scheduled steel industry: the circular economy.
Regenerative and restorative in principle, the concept aims to eliminate the notion of waste, keeping materials in use for as long as possible and thus bringing economic, social and environmental benefits to society.
Decreased amount of raw materials and energy used for production and weight reduction of products. In 2017, 57% of the power consumption of the plants was supplied through self-generation (49% in thermoelectric and 8% in hydroelectric).
Reuse of materials or products classified as durable goods is the extent of use of a post-consumer product while maintaining the same function that it performed.
Steel is the most recyclable material in the world. Can be continuously recycled without quality loss 8.9 million tonnes of steel scrap was recycled in 2017.
Remanufacturing transforms used and / or defective products into new products with a new life cycle.
Unlike the linear economic model (extraction, production, consumption and disposal), the circular economy has the principle of reduction, reuse, remanufacturing and recycling of materials and products, bringing as benefits the conservation of raw materials, management efficiency. emissions, emission reductions, innovations and jobs.
Linear Economics vs. Circular Economics
Decreased amount of raw materials and energy used for production and weight reduction of products. Example: development of new, thinner and more resistant steels, which make it possible to produce cars with lower weight and greater safety for users.
Reuse of materials or products classified as durable goods and the extent of use of a post-consumer product while retaining the same function as it performed. The reuse process involves checking and cleaning. Example: car doors, rails, water, etc.
Recycling means recovery of the raw material without conserving its main structure. The recycling process involves product collection, selection of the item to be recycled, preparation for recycling, industrial process and consequent reintegration of the recycled material into the production process as raw material. Example: bridges, cars, construction steels, metal packaging, etc.
Remanufacturing transforms used and / or defective products into new products with a new life cycle. The remanufacturing process involves carcass collection, product disassembly, part cleaning, part inspection and screening, component replacement or repair, product reassembly, and testing. Traditionally remanufactured products are engines, machine parts and turbines.
Steel is a material that has always been intrinsically associated with the concept of circular economy. It is the most recyclable and recycled material in the world. Automobiles, refrigerators, rebar and all other steel products are, at the end of their useful life, collected and returned to the steel mills, producing steel with the same quality excellence.
Today, in Brazil, about 30% of all steel produced comes from recycling. Whatever the source of scrap, the steel recycling cycle produces new steels that can be used for any of its purposes: cars, construction, packaging, etc. The economy profits from the absence of waste and so does the planet. What was only an end becomes a fresh start.
The steel cycle is the cycle of life. Steel is in human relationships, consumer dreams, hope for healing, the intimacy of homes, and the ideals of ...
