Fuel consumption data—mostly obtained by Suzano in an automated way—were converted into energy consumption based on the basic density and lower heating value of each fuel. In this sense, when available, the data contained in the technical specification sheet of the fuel used were adopted. When not available, the values presented by the National Energy Balance (MME, 2019) were used.
In 2020, there was a reduction in energy consumption from biomass with an increase in the use of black liquor, which is a by-product of the process and considered a renewable fuel. In our logistics operations, there was also a higher consumption of ethanol in replacement of gasoline.
