Atiaia Energia

Small hydroelectric power plants are considered to be low environmental impact enterprises. In addition to this, Atiaia Energia develops and implements various socio-environmental preservation programs in the regions and communities in the vicinity of its plants, and rigorously complies with all the requirements of the environmental permits issued by the competent agencies. All its plants operate under a run-of-river system, where reservoir levels are automatically regulated and remain constant without changing the flow of water in the river.


The plant uses the most modern sustainability practices in the world and is the only one in the country to use 100% recycled water and silver in its mirror glass production process. A benchmark in energy management, it is the only company in Brazil that uses L.E.M.™ (Low Energy Melter) in its production process, a technology which reduces greenhouse gas emissions in relation to the global average of industries from the same segment. The use of a less polluting energy matrix for melting glass, waste management (broken glass and trash sorting), rainwater harvesting for use in the production system and continuous reuse of effluents generated by the unit, among other initiatives, also help make the process more eco-friendly.

Iron House

The company's modern and responsible design of urban venues provides a new way of living, that also respects and values the cultural, historical and environmental assets of their locations. At the Camassarys Reserve, in Bahia, the landscaping was designed to enhance the biodiversity of Brazilian flora, including the planting of the Camassary – a tree that gave rise to the city's name. The Hotel São Paulo at Nações Unidas has LEED (Leadership in Energy and Environmental Design) international certification, attesting to its compliance with sustainability requirements, such as energy management optimization, reduced carbon emissions and green construction, through the use of recycled materials with low environmental impact

Cimento Bravo

To maximize the efficiency, competitiveness and sustainability of its operations for unloading clinker – the main raw material for cement in the São Luís unit – from the vessels, Cimento Bravo purchased two ecological hoppers. This equipment is composed of exhaust filters and outlets, among other mechanisms that reduce particulate emissions. Through the use of these hoppers, the unloading of material has become an example of a clean, safe and efficient operation.
