Historic Reform Marks Partnership Between Valmet and Suzano and Ensures Modernization Without Stopping Production

Valmet, a global leader in process technologies, automation, and services for the pulp, paper, and energy sectors, is conducting the largest diffuser reform ever recorded in the pulp market. The project, which started in April 2024 with the technical proposal, will be executed at the Suzano unit in Mucuri, southern Bahia, and is expected to be completed by April 2027, according to an official company statement.

Strategic Modernization Without Compromising Production

According to Valmet, the project involves the recovery of seven diffusers, with three in the brown pulp washing line and four in the bleaching process. In addition, the intervention aims to restore mechanical conditions, modernize components, enhance processes, and optimize controls. Thus, the goal is to ensure reliability, availability, and greater efficiency in industrial performance.

The company further states that the execution occurs in a staggered manner, ensuring that a complete factory shutdown is not needed, a strategy that preserves the continuity of production.

Team Integration and International Synergy

According to the company, professionals from Brazil and Sweden are working together. There is synergy among different areas of Valmet, ranging from mechanical manufacturing at the Araucária (PR) Service Center to transport logistics, component recovery, and field assembly.

Valmet’s sales engineer, Edemilson Teodoroski, emphasized that “the solution was built collaboratively by teams from various Valmet areas, aiming to deliver the best results for Suzano.”

EPC Model and Technological Advancement

The project was structured in the EPC (Engineering, Procurement, and Construction) format. In this model, Valmet takes on the complete scope, including:

Basic and detailed engineering
Supply of main and auxiliary equipment
Mechanical, electrical, and instrumentation assembly
Field supervision
Project management
Commissioning and start-up

This approach ensures that all stages are under the direct responsibility of the company, reinforcing control, integration, and efficiency.

Execution Details and Timeline

According to the project manager, Eduardo Mahfoud, the equipment will be refurbished in stages. He explained that five diffuser screens will be restored in Mucuri, while a new double screen will be produced in Araucária (PR).

He added that “the transfer of professionals from Valmet’s workshop to Suzano’s unit is crucial to ensure local execution of the stages.”

The timeline includes:

April 2024: technical proposal preparation
Beginning of 2025: contract signing and engineering plan development
April 2027: expected completion of the reform

Importance of the Project for the Pulp Sector

The Mucuri plant had already recorded production records in 2022, according to Suzano. Therefore, the reform is seen as a milestone for maintaining the competitiveness of the factory and the pulp sector in Brazil.

Additionally, the project reinforces the long-standing partnership between the companies. According to the statement, this relationship is sustained by innovation, efficiency, and commitment to consistent results.

Importance of the Project for the Pulp Sector

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.

An astronaut spent 340 days in space while his twin brother stayed on Earth, and NASA found a “rejuvenating” effect, genes, microbiome, cognition, and immune system that revealed the biological cost of living outside the planet.

Xiaomi launches new smart stove with titanium sensor and automatic shutdown that detects an open flame without supervision.

China has just successfully tested the world’s first ground effect maritime vehicle, a craft that flies up to 6 meters above the water at 200 km/h, uses quantum technology and 6G communication, and can rescue patients in the middle of the ocean.

The R$ 61.7 billion deficit in government accounts in 2025 will trigger the fiscal framework’s mechanisms for the first time, and starting in 2027, personnel spending will only be able to grow 0.6% above inflation, which could freeze salary adjustments and public service entrance exams.

Prepare your heavy umbrella: Maranhão, Piauí, and Ceará go on alert at the end of April with up to 100 mm of rain per day, winds that could reach 100 km/h, risk of flooding and lightning strikes, as the northern coast of the Northeast becomes the main corridor for storms.

The first intense polar air mass of 2026 will place São Paulo at the center of the cold at the turn of May to June, with temperatures near 10 °C and an extreme contrast with the North and Northeast still above 36 °C during the same period.
