Arcelor Mittal

A steel processing plant with a smaller environmental footprint

When it acquired a site in São Francisco do Sul in southern Brazil during the early 2000s, Arcelor Mittal – the world’s largest steel producer – was hoping not only to expand its production capacity but also to build a plant that would serve as a model in terms of respect for the environment. The group’s aim was to continue focusing on its chosen field of excellence, steel processing, while joining forces with an international expert in environmental solutions. For this, it chose Veolia. 

A unique approach

Veolia created CLE Brasil, an ad hoc subsidiary that brings together its full range of expertise in waste, water and energy management, and hired a workforce of 60 employees from the local community to handle its aray of services for Arcelor Mittal. The name CLE is in honor of the first French ship to visit São Francisco do Sul, the Consortium L’Espoir, which landed in 1504. 

Veolia managed the project’s financing and construction and currently operates all of the site’s multi-utility installations (complete water cycle, waste treatment, wastewater treatment, industrial gas, electricity and more) on behalf of Arcelor Mittal. The facility boasts ISO 9001, 14001 and OHSAS 18001 certification. Security issues are also at the heart of Veolia’s operations and the CLE has not reported any accidents since its creation.
