We expect these solutions to deliver strong performance while reducing energy consumption and ensuring our capacity goals. We value the long-standing relationship we have built with Valmet and look forward to continuing our cooperation with this new project," says Ying Guangdong, Vice General Manager and Chief Engineer of Sun Paper.
