"Sucuriú (the "Project") is an integrated development for the construction and operation of a pulp mill located 50 km from the municipality of Inocência, in the state of Mato Grosso do Sul, Brazil. The Project will be executed by Celulosa Arauco y Constitución SA ("Arauco"), a leading Chilean company in forestry and timber products, headquartered in Santiago.


"The investment planned for the Project is US$4.6 billion to establish one of the largest pulp plants in the world, with an estimated annual production capacity of 3.5 million tons of short fiber pulp. Construction is expected to begin in 2025, with operations beginning in late 2027. The plant will be supplied by 400,000 hectares of sustainable eucalyptus plantations owned by Arauco," the IDB Invest says.
"
The transaction will be structured as an A/B Financing Loan of up to US$500 million, with a term of up to 10 years and a grace period of up to 5 years. The resources will be allocated to construction, specific development of the Project's infrastructure, management of plantations and implementation of renewable energy facilities, promoting sustainability through water reuse, energy efficiency and emissions reduction."

"“Arauco has been looking into expanding pulp production in Brazil for years. Our target was to enhance our competitive position, and Brazil has the required conditions, including logistics infrastructure, skilled people, and the right environment for trees to grow," the Valmet says.


"We selected Mato Grosso do Sul state and the city of Inocencia as the location for our project,” explains Iván Chamorro, Senior Vice-President Forestry & Woodpulp Business for the Arauco Group.


"Valmet is a key player in this project, delivering all the key process areas in an EPC model. We’re very happy so far with our relationship and Valmet’s commitment. We’re very confident that together we’ll be able to deliver the best mill. We know we’re going to face challenges, but with strong communication between the technical teams and at the management level, we can face these challenges and be successful together,” Chamorro explains."
