Historic

Our main sources of atmospheric emissions for the Steel, Mining and Cement sector are mainly particulate matter (PM), sulfur oxides (SOx) and nitrogen oxides (NOx). In this way, the Company promotes the management of atmospheric emissions, which can be mobile or fixed, so we have strict controls and monitoring of these emissions. We also maintain air quality monitoring stations around our operating units, mainly in Volta Redonda – RJ, where the Presidente Vargas Plant is located.
