Suzano’s energy mix is mostly supported by renewable sources such as biomass, which is composed of bark, logs, and trimmings from the wood chipping process; and liquid biomass, also called black liquor, responsible for generating the largest percentage of energy. In some units, the use of biological sludge in biomass boilers is already in place. In 2020, 87.18% of Suzano’s energy mix came from renewable sources.
In some production units, a surplus of electricity is generated, which is supplied to the national grid (SIN – National Interconnected System), further expanding the degree of renewability of the Brazilian electrical mix. Between 2019 and 2020, we expanded exports of surplus renewable energy by approximately 6%. Projects to replace the energy generated by burning fossil fuels with renewable energy using black liquor generated in our production process had direct contribution to this percentage.
Brazilian diesel, ethanol, and gasoline are the most commonly used fuels in forestry and logistics operations.
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.
The total energy consumed represents the sum of the energy generated from renewable sources, the energy acquired from the National Interconnected System, less the energy sold.
