Stora Enso has decided to install a new steam turbine with a closed-loop cooling system and additional biomass storage at its mill in Maxau, Germany. The investment cost is approximately EUR 25 million and implementation of the project is scheduled to start during the third quarter of 2018 with completion in 2020.
Stora Enso wants to secure the long-term profitable energy production in Maxau Mill by increased electricity generation and higher efficiency. The new 57 MW extraction-condensing turbine complements the existing Combined Heat and Power (CHP) plant which started up in 2010. The investment will reduce the energy cost and secure long term cost competitiveness of the paper mill. Once installed, the payback time will be around four years.
The investment contributes to Stora Enso’s carbon neutral roadmap and science-based targets through higher share of biomass and higher efficiency ( >50 000t CO2 savings per year). The closed loop cooling system will relieve the Rhine River significantly by less thermal output and considerably lower river water extraction.
Located on the Rhine River near Karlsruhe in southwest Germany, Maxau Mill is the key pillar in the Uncoated Magazine Paper (SC) product segment.
The two paper machines produce approx. 530 000 tonnes of uncoated magazine papers per year. Paper for Recycling (PfR) serves as the main raw material for the paper production.
