Nippon Paper Industries partners with ANDRITZ on new high-efficiency recovery boiler to reduce emissions at Ishinomaki mill

(IN BRIEF) Nippon Paper Industries has selected ANDRITZ to supply a state-of-the-art recovery boiler for its Ishinomaki pulp mill, scheduled for start-up in 2028. The 2,200 tds/d boiler will allow the shutdown of one coal-fired unit and two recovery boilers, cutting greenhouse gas emissions while improving efficiency and sustainability. The project, executed with Japanese EPC partner Kanadevia, also includes a high-dry solids concentrator and an ash leaching system to optimize chemical recovery. Executives from both Nippon Paper and ANDRITZ highlighted the project’s importance in reducing emissions, strengthening competitiveness, and reinforcing their long-term collaboration.

(PRESS RELEASE) GRAZ, 1-Sept-2025 — /EuropaWire/ — Nippon Paper Industries Co., Ltd. has awarded ANDRITZ, the international technology group, a contract to supply a new high-efficiency recovery boiler for its Ishinomaki pulp mill in Japan. The project will be carried out in collaboration with Japanese EPC partner Kanadevia, with commissioning planned for 2028. The order, booked in the second quarter of 2025, includes advanced automation and digitalization technologies to optimize boiler performance.

The new recovery boiler, with a capacity of 2,200 tds/d and steam parameters of 8.3 MPa and 505 °C, is engineered for long operating cycles and superior steam generation. Once operational, it will enable the decommissioning of one coal-fired boiler and two existing recovery boilers, significantly cutting greenhouse gas emissions while improving the mill’s energy efficiency and overall sustainability.

In addition to the boiler, ANDRITZ will deliver a high-dry solids concentrator with pressurized storage tanks to boost black liquor firing efficiency, and an ash leaching system to recover sodium and sulfate while removing chloride and potassium from electrostatic precipitator ash. These features will strengthen the mill’s chemical recovery cycle and support more environmentally friendly operations.

Mr. Yoshinori Matsubara, Executive Officer, Head of Energy Business Division at Nippon Paper Industries, commented: “This high-efficiency recovery boiler will play a crucial role in lowering emissions at our Ishinomaki mill. By applying the expertise gained from this project, we aim to further enhance our competitiveness and sustainability across other sites.”

Masato Tsuchitana, General Manager at ANDRITZ in Japan, added: “We are grateful for Nippon Paper Industries’ trust in our technology and team. This project underscores our commitment to delivering the most efficient and cost-effective solutions, and we look forward to building on this collaboration.”

The Ishinomaki project demonstrates ANDRITZ’s continued leadership in supplying state-of-the-art pulp mill technologies, with a focus on environmental performance, cost efficiency, and long-term operational reliability.
