ANDRITZ Secures Nanning Sun Paper Pulp Mill Contract

Nanning Sun Paper Co., Ltd. has awarded international technology group ANDRITZ repeat orders to supply main process technology and key equipment for its third pulp mill line and the new PM21 paper machine in Nanning, Guangxi Province, China. Scheduled for start-up in mid-2027, the orders are valued in the mid double-digit million-euro range. Ying Guangdong, Vice General Manager and Chief Engineer of Sun Paper, emphasized that the decision reflects the company's confidence in ANDRITZ’s proven technology to support efficient, reliable, and sustainable production.

The comprehensive scope of supply features three ANDRITZ 360° Stacker Reclaimers, a high-kappa fiberline capable of processing 1,500 adt/d of softwood and 2,200 adt/d of hardwood, and an energy-efficient recovery boiler designed to maximize green electricity production. Furthermore, ANDRITZ will deliver a white liquor plant with an integrated circulating fluidized bed (CFB) gasifier, enabling fossil-free lime kiln operations. For the PM21 paper machine, advanced refining, screening, and approach flow systems will be implemented to ensure optimal stock quality and cleanliness for high-grade packaging paper production.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

The Chinese paper and pulp sector is rapidly shifting towards integrated operations that prioritize circular economy principles and decarbonization. Technologies such as high-kappa continuous cooking and multi-stage drum displacer washing drastically reduce a mill's freshwater footprint and chemical consumption, addressing stringent environmental regulations. The inclusion of a CFB gasifier within the white liquor plant is a critical sustainability upgrade, allowing the lime kiln to operate using renewable biomass gas rather than fossil fuels. Ultimately, these integrated solutions enable large-scale industrial parks—like Sun Paper's planned 5.25 million-ton capacity site—to meet the growing domestic demand for packaging materials while optimizing their carbon footprint and operational costs.
