Additional information

The fuel consumption data - collected by Suzano in a mostly automated way - were converted into energy consumption from the basic density and the lower calorific value of each fuel. In this regard, when available, the data contained in the technical specification sheet for the fuel used were used. When not available, the values presented in the National Energy Balance (Ministry of Mines and Energy, 2021 - MME in Portuguese) were used.

In 2021, as in 2020, there was a reduction in energy consumption of Biomass and an increase in Black Liquor, which is produced as a byproduct of the process and is considered a renewable fuel. This increase was due to the 107% increase in production compared to the previous year.
