Project MA-1100 will raise the mill's production capacity for paper and board from 700,000 tons per year (t/a) up to 1.1 million t/a. The focal point of the project is PM9, a 350,000 t/a liquid packaging board machine.
The project includes a new woodyard, a CTMP mill (using 100 per cent eucalyptus), a ClO2 plant, a coating kitchen for PM 9, two sheeters, a lime kiln, one evaporator effect (and concentrator), recovery and power boilers (power boiler started up in April 2008) and a turbo-generator.
The Monte Alegre mill virtually duplicated its effluent treatment plant while adding a tertiary treatment stage.
Pöyry was involved in 2002-2003 during the early project phases when a long-range planning strategy was discussed. When the Monte Alegre mill was chosen for expansion, Pöyry conducted the pre-engineering, one year before the implementation decision. The work later covered the complete balance-of-plant (BOP) part of the project, including equipment, material engineering, construction and erection.
Pöyry also provided owner's engineering services and detail engineering services for various engineering, procurement and construction packages.
The expansion project will place the Monte Alegre mill among the ten biggest paper mills in the world. The expansion project will provide a range of social and environmental benefits for the Telemaco Borba region, where the Monte Alegre mill is located.
