Steelmaking Process

CSN operates across the entire steel production chain, from the extraction of iron ore to the production and sale of a diversified range of steel products including, but not limited to sheets, coated, galvanized steelpre-painted steel, metal sheets and long steel products (rebar and wire rod). The Company has units in Volta Redonda and Porto Real, both in the state of Rio, it also has a unit at Araucária, in Paraná. Abroad, there are units in the Portugal (Lusosider) and Germany (SWT).

In addition, the company has a strong steel distributorPrada Distribuição, and a unit specialized in packagingPrada Embalagens (SP) and Prada Resende (RJ).

An integrated business model and quality management enable CSN to have one of the lowest production costs of the global steel industry.

Environment

Possible destination of waste, obsolete equipment and material, to reduce the volume of waste sent to landfills.

Artboard 1

Internal use in the production process, such as steel scrap or coper from discharged electrical cables.

Sale of materials that gain added value after proper separation and processing, such as cardboard, plastic and shredded paper. There are also other separated recyclable materials sold in bulks such as zinc dross, stainless steel scraps, electric material scraps, refracting material scraps, pallets and wood, among other.

Destinação dos materiais para um fornecedor licenciado para o descarte ambientalmente correto. Nesse caso, estão contemplados resíduos classe I, entre eles: lixo contaminado em tambores, borra oleosa, resíduo de gás de coqueria, fibra cerâmica contaminada. Esses materiais são suportados por contratos de destinação e encaminhados para coprocessamento na indústria de cimento ou para aterros licenciados.

A Usina Presidente Vargas é a única siderúrgica do país a realizar a pegada hídrica e é a planta da CSN com o maior consumo de água; nessa unidade, somos referência ao reciclar e reutilizar 93,6% da água em 2020.

POWER PLANT PRESIDENTE VARGAS (UPV)

Water recycling and reuse at UPV

Note: The reduction in water recycling and reuse rate is due to Turbo Generator 3 resuming operations at UPV’s Thermal Power Plant -1. Although the unit has maintained water reclaim flow in its operating process, there has been an increase in water withdrawal to serve turbo generator 3’s demand, which is fueled by gases from steelmaking process at UPV and, therefore, is a positive element in power generation. Thermal Power Plant 1 is a cogeneration plant fueled by steelmaking gases to generate power and process vapors.

Biodiversity UPV

Aware of the importance of the conservation and preservation areas we maintain, we support and work in partnership with institutions such as ICMBio (Chico Mendes Institute for Biodiversity Conservation) in the environmental management of such areas. The partnership is intended, for instance, for the management of the Hemlock Forest ARIE (Area of Important Wildlife Interest), located in the city of Volta Redonda (RJ), with 131.28 hectares covered by the Brazilian Atlantic Forest Biome, a very important local and national area, to preserve natural resources that remain untouched in the region.

Conservation of 131.28 hectares of the Brazilian Atlantic Forest Biome

Planting and maintenance of 8,000 native seedlings from the Atlantic Forest by the end of 2020

The planting of seedlings in Volta Redonda’s urban areas, creating carbon credits for future Presidente Vargas Steelworks’ offsetting. Every tree suppression is cautiously evaluated with the respective justifications and is executed only as a last resort. CSN’s carbon credit bank foresees offsets equal to 6x1 (for each suppression, 6 seedlings should be planted and maintained), in compliance with Law 12.305/2010 (National Solid Waste Act).

Seedlings donated by CSN to the Local Government of Volta Redonda (RJ)

Air Quality

In the city of Volta Redonda (RJ), we have three automatic and five semi-automatic air quality monitoring stations, in addition to weather stations, in order to provide transparency to our environmental controls and air quality indicators. Air emission monitoring at UPV, as well as at the cement plants in Volta Redonda (RJ) and Arcos (MG) is performed through isokinetic (gas flow on the equipment entrance had the same speed as gas flow we intend to analyze) and continuous measurement, via automatic particulates and gas meters.

We continuously monitor our air emissions to ensure air quality is within the standards determined by law, without putting the population’s health at risk. 

To soften and mitigate the air pollutant emissions from fixed sources, we use the best environmental control technologies in our equipment. At Presidente Vargas Steelworks, for instance, we have Bag House and Electrostatic Precipitators Dust Collector Systems.

Goal

We set the goal to reduce particulate emission per ton of crude steel by 40% until 2030, compared to 2019.

Inclusion of Women: UPV records 31% increase in the number of female employees in 2019.

In 2018 and 2019, we worked hard on the technical training of women in order to raise awareness of employees and foster inclusion at CSN through guided opportunities. Therefore, we recorded a 31% increase in the number of female employees at UPV, compared to 2018, closing 2019 with 1,264 women.
