Eldorado Brasil Celulose inaugurated, in partnership with Valmet, the Waste Wood Biomass Processing Center – a new chipping line that improves quality and guarantees the production of biomass for renewable energy generation.
The project is located within the Eldorado industrial complex in Três Lagoas (MS). The process is now carried out using equipment that runs on electricity produced by the factory itself.
The line uses wood logs that were not used in the production of cellulose, reinforcing the full use of forestry waste and expanding the company's energy matrix with renewable sources.
Prior to the new facility, biomass was processed in the company's forests using equipment powered by Diesel. With the implementation of the chopping line within the factory, the operation began to use renewable energy generated by Eldorado Brasil itself, eliminating the use of fossil fuels.
This change made the operation more efficient and sustainable, allowing a production capacity of up to 1.500 tons of biomass per day, considering 12 hours of effective chopping.
The construction of the new processing center was a large-scale project, started in 2023 and involved several areas of Eldorado's industrial engineering.

The process, which is fully automated, begins with the arrival of trucks loaded with wood logs that are not used in pulp production.
A mobile crane removes the wood and deposits it on the feeding table, which takes it along a conveyor belt equipped with a metal detector to a drum chipper.
The equipment, powered by electric motors, transforms wood into biomass, which is automatically deposited in a chipper truck.
The biomass then goes to the Onça Pintada Thermoelectric Plant, where it is unloaded and directed to the power boiler, ensuring the plant's supply and its conversion into renewable energy.
This energy generated at the thermoelectric plant is integrated into the national electricity grid, contributing to the supply of sustainable electricity.
According to Marcelo Martins, Eldorado's industrial general manager, the megaproject allowed the company to improve the quality of the biomass produced, reducing the amount of waste and dust emissions in the process.
“This change ensures that the quality requirements of the Onça Pintada Thermoelectric Plant are met, reinforcing the efficiency and sustainability of the operation. Furthermore, by replacing diesel with renewable energy, we also reduce carbon emissions and increase the company’s energy independence,” he said.
