Valmet will supply a folding boxboard making line (BM 1), a fine paper making line (PM 3) and a bleached chemi thermo mechanical pulp (BCTMP) production line to Liansheng Pulp & Paper (Zhangzhou) in Zhangzhou, Fujian province, China. The lines will be delivered to a new greenfield mill in Zhangzhou, which will eventually have a total pulp and paper capacity of 3.9 million tonnes annually. The start-ups of BM 1, PM 3 and BCTMP line are scheduled for the third quarter of 2022.
The orders of BM 1 and PM 3 are included in Valmet’s orders received of the first quarter 2021. The order of BCTMP line was included in Valmet’s orders received of the fourth quarter 2020.
The values of the orders will not be 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.
“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,” says Rongjun Xue, Vice General Manager, Liansheng Paper.
“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 to 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,” says Xiangdong Zhu, Area President, China, Valmet
