Self-sufficiency in bioreductant production 


We are self-sufficient in bioreductant production, one of the most essential inputs for ferroalloys production.

We have over five thousand hectares of eucalyptus reforestation.

Our annual capacity reaches around 39 thousand tons produced in five different charcoal plants.


Respect to the environment 

We use clean electricity with 100% of our energy consumption from renewable sources. We consume bioreductants mainly from eucalyptus reforestation.

We contribute to the preservation of biodiversity with more than 5.300 hectares of native woods.

Our solid environmental policy ensures the treatment and reuse of all the residues generated during the productive process.

We are the only manganese ferroalloy producer in the State of São Paulo, where we are served by an extensive highway network, which ensures easy access to the steel industry national park and to the main ports of the southeast region.
