International technology group ANDRITZ has successfully commenced operations at a new pulp mill for Brazilian pulp producer Suzano in Ribas do Rio Pardo, Mato Grosso do Sul. Once fully operational, this facility will be the world’s largest single-line eucalyptus pulp mill, boasting an annual production capacity of 2.55 million tons.
Remarkably, the mill will operate without fossil fuels, utilizing 100% planted trees as raw material. It will be energy self-sufficient, generating surplus green power for local suppliers and the national grid.
“This new pulp mill will increase our production capacity while significantly reducing our environmental impact, supporting our financial and environmental goals. The cutting-edge technologies applied are in line with our commitment to sustainability and innovation. Trust and reliability are essential in a project like this, and we found both in our partnership with ANDRITZ,” stated Maurício Miranda, Director of Engineering at Suzano and responsible for the construction of the mill.
ANDRITZ provided a highly resource-efficient pulp mill featuring advanced technologies for fiber production and chemical recovery on an EPCC basis (Engineering, Procurement, Construction, Civil Works). The supply included a comprehensive wood processing plant with five chipping lines, the world’s largest single-line fiberline (capacity over 8,000 adt/d) with unique washing and bleaching technology based on DD-Washers, an innovative pulp drying system with two energy-efficient drying lines, an energy-efficient black liquor evaporation plant, a HERB recovery boiler to maximize steam production for power generation, a biomass power boiler utilizing ANDRITZ EcoFluid Bubbling Fluidized Bed (BFB) technology, and a complete white liquor plant with recausticizing plant and two lime kilns.
To further enhance the mill’s environmental performance, ANDRITZ is also providing gasification plants for fossil-free operation of the lime kilns and a SulfoLoop sulfuric acid plant to produce commercial-grade sulfuric acid from the mill’s concentrated odorous gases and elemental sulfur. This innovation will recycle sulfur from waste streams, making the mill completely self-sufficient in sulfuric acid.
“We are honored that Suzano has chosen us as their EPCC partner for the implementation of this flagship project, using our most advanced technologies for efficiency and circularity,” said ANDRITZ Executive Board Member Jarno Nymark.
