The order was included in Valmet's orders received for the second quarter of 2026. The value of the order exceeds EUR 100 million. The exact value of the order will not be disclosed. The new mill is expected to start up in June 2028.
"This project is at the core of our strategy to improve our self-sufficiency in raw material supply and meet the evolving needs of customers in the Chinese market. We chose Valmet as a partner for this project based on our positive previous experiences and their ability to meet our project needs both regarding technology and our investment budget," says Jeff Cheng, Vice President, Century Sunshine.
"Valmet has a long-term partnership with Century Sunshine with our paper technology, and we will now strengthen our cooperation with this pulp mill delivery. This delivery showcases not only customer trust in Valmet but also highlights our competitiveness in China. For example, we have increased the share of locally manufactured parts for the evaporation plant. With our strong local technology and service organization in China we will be able to support the customer throughout the mill's lifecycle," says Xiangdong Zhu, Executive Vice President, China Chair, Valmet.
"The new Century Sunshine Rizhao mill will produce fluff, dissolving, softwood and hardwood pulp, and is an excellent example of product differentiation to meet the growing market needs with Valmet's full scope offering. The mill features the latest cooking technology, a high-power recovery boiler with leading optimization and safety features, and electrostatic precipitator for efficient dust emissions reduction," says Andreas Michalik, Vice President, Pulp Mills, Pulp, Energy and Circularity Business Area, Valmet.
Energy efficiency and long-term availability in technology focus
Valmet's delivery for the new Century Sunshine Rizhao mill includes complete cooking and fiberlines, and the recovery island.

The recovery island consists of an Evaporation plant with Valmet Tubel technology, a high-power Recovery Boiler, an Ash Crystallization plant, a Recausticizing plant and two Lime Kilns with integrated Biomass Dryers and Gasifiers.
