Valmet to supply PM rebuild to Sappi North America’s Somerset mill

Valmet has confirmed it will supply an extensive rebuild for Sappi’s Somerset paper mill in Skowhegan, Maine, USA. Previously, Valmet rebuilt the PM1 and Sappi has chosen the company again to rebuild the PM2.

As a result of the PM2 conversion from coated woodfree graphic paper to solid bleached sulphate board, the machine capacity will be increased from 240,000 tons to 470,000 tons per annum. The start-up of the rebuilt machine is scheduled for the mid-year of 2025.

“Valmet has proven to be a trusted supplier to Sappi over the years and we’re pleased to work with them again on our PM2 project. This investment is fully aligned with our Thrive25 strategic focus to reduce our exposure to graphic paper and transition our portfolio to packaging and specialty papers, pulp and biomaterials,” says Michael Haws, President and CEO, Sappi North America.

“We look forward to continued collaboration with Sappi North America, and we thank them for their partnership on another conversion project. We know the demand for packaging and specialty papers in North America is high and we’re confident that through our combined efforts, we’ll meet future market needs,” says Jukka Tiitinen, Area President, North America, Valmet.

PM2 will be rebuilt using some of the most advanced packaging manufacturing technology to produce a variety of both packaging and coated paper products. Valmet’s delivery will include a number of modifications and new machine parts in the existing machine to meet the requirements of the new packaging grades. In addition, the mill will benefit from Valmet Industrial Internet and Automation Solutions including a new Quality Measurement System, a Process Control System (DCS and Valmet DNA), web monitoring and web inspection systems.
