Valmet will deliver a new recovery boiler, an ash crystallization plant, and an odorous gas handling system to Klabin’s Monte Alegre pulp and paper mill as part of Klabin’s announced modernization project. The delivery includes automation and flow control solutions consisting of extensive optimization systems and control valves. The new equipment is estimated to be taken into operation by the end of 2026.

The value of an order of this size with extended scope is typically above EUR 100 million. The delivery is part of Klabin’s investment of about EUR 285 million that seeks the operational continuity of the Monte Alegre mill.

“Klabin Monte Alegre mill modernization project aims to increase the efficiency, competitiveness, and sustainability of the mill, the largest paperboard producer in Brazil. We strategically chose Valmet because of its technology, suitable interface with the recovery plants, and a good plan for implementation and assembly,” says
Edemilson Schroeder Pagano, General Project and Engineering Manager, Klabin.

“The new recovery boiler and ash crystallization system represent high-technology solutions that will give performance and optimized OPEX for Klabin’s Monte Alegre mill. This new project reinforces the long-lasting partnership between Klabin and Valmet in developing sustainable solutions together. All of us at Valmet are proud to be part of this significant modernization project,” says Fernando Scucuglia, Pulp & Energy Director, South America, Valmet.

“The new recovery boiler and ash crystallization with connected optimizers will improve the mill’s safety and operational reliability. The collection, handling, and incineration of non-condensable gases will also help reduce the environmental impacts,” says Jussi Mäntyniemi, Vice President, Recovery, Pulp and Energy, Valmet.

The Valmet Recovery Boiler includes several high-power features to maximize energy efficiency. Leading safety solutions and advanced process controls for optimized performance and high-performance predictability support the operation. The boiler will have a capacity of 1,950 tonnes of dry solids per day (tDS/d).
