Fujian Liansheng Paper Co., Ltd. is a leading modern papermaking enterprise integrating product development, waste paper recycling, waste paper pulping, papermaking, sales, and logistics. The company is located in the Zhangzhou Taiwanese Investment Zone, which is adjacent to Xiamen and produces 2.6 million tonnes of packaging paper annually.

Valmet was chosen to be the supplier for BM 1, PM 3, and BCTMP line due to their smaller environmental impact, low operation cost, good reference mills, and our good long-term cooperation. We valued highly the fact that Valmet has a strong reference base for both coated board and paper making lines, one example being the successfully started-up PM 10 of Fujian Liansheng. For the BCTMP, this is our first BCTMP plant and it will have a very large capacity. Prior to this investment, we did a lot of investigation in concept selection and technical evaluation, said Rongjun Xue, Vice General Manager, Liansheng Paper.

The start-ups of BM 1, PM 3, and BCTMP line are scheduled for the third quarter of 2022. While the values of the orders have not been disclosed, the orders similar to delivery scopes of BM 1 and PM 3 add up to around EUR 190-220 million, and the value of an order similar to the delivery scope of the BCTMP line is typically around EUR 10-20 million.

For the BM 1 and PM 3 lines, Valmet energy-efficient technology and good references, such as the market benchmark machine of Ningbo PM 4, were definitely key aspects in Liansheng’s decision. We had lots of discussions with the customer, including raw material types, final product properties, future considerations for pulp and paper balance as well as chemical and energy balance. Our BCTMP solution fits customer’s needs from all aspects and the state-of-the-art concept with low operating costs helps them to secure their competitive position in the future market,” said Xiangdong Zhu, Area President, China for Valmet.
