Abstract

ArcelorMittal Tubarão is an internationally renowned steel producer, with a production capacity of 7.5 million tons of steel slabs and hot rolled coils per year. Since its start-up in 1983, Tubarão has had water management as its central theme, and currently has the lowest index of industrial consumption of fresh water in Brazil. At the plant, 96% of the water used by the company comes from the sea and is used for steel production equipment cooling. In line with the company's strategy against future water scarcity scenarios, in 2021 a seawater desalination plant was built with a production capacity of 500 m³/h of water for industrial purposes, replacing part of the volume consumed by the company from the Santa Maria da Vitória River, and thus allowing greater availability of the resource to society and improving company water security.
