In October 2023, DS Smith's Viana Paper Mill completed the rebuild and start-up of its PM 4, increasing production from 400,000 to 430,000 tons of kraftliner per year. The rebuild, which included upgrades to the wire section, press section, web transfer, and stock preparation, improved the mill's efficiency and reinforced its leadership in Southern Europe. The rebuild also focused on sustainability, achieving a 15% reduction in steam usage, a significant increase in production, and nearly 90% fewer paper breaks. The project, completed in collaboration with Voith, met DS Smith's decarbonization goals by reducing energy consumption and enhancing the sustainability of kraftliner production.
