The company produces all the electricity it needs for its activity of pulp production through cogeneration. This process is based on the use of vegetable components with fuel properties and that are not suitable for the production of paper pulp (lignins), which are then burned in the recovery boiler to produce steam.

The high pressure steam produced in the boiler is expanded in a turbine, and is subsequently used in the process at medium or low pressure. The energy released by the steam expansion in the turbine is converted into electrical energy, which, on average and in normal operation conditions, meets the needs of the factory. The internal system of electricity distribution in medium voltage of the factory is connected in parallel permanently with the national grid, enabling energy trading (buying and selling).

At the same time, the forest biomass is used by the power plant (owned by EDP Produção Bioelétrica with 50% and the other 50% by ALTRI) to produce energy from renewable resources resulting from the cleaning of forests and biomass of plant origin. This is then injected into the national electric grid.
