Smurfit Kappa chops CO2 emissions with innovative steam system
Smurfit Kappa Roermond paper mill’s integrated steam system has been held up as an example of sustainability for reducing its CO2 footprint by a further 3% in 2018. The steam project is part of an on-going, intensive energy and CO2 reduction programme at the mill which has achieved a specific CO2 emission reduction of 23% since 2005.
Roermond’s three paper machines produce paper for corrugated packaging from recycled paper. Under the previous configuration, the residual steam of two of the machines was only partially re-used. As part of the mill’s on-going project to reduce carbon emissions, it integrated the steam systems from all three paper machines by incorporating a sophisticated control system. The machines operate at different speeds using a variety of paper weights which added to the complexity of the task.
Wim Janssen, energy and production technologist at the mill, said: “We started by carrying out an in-depth analysis of processes to figure out a way to re-use excess steam from two of the machines in the third machine. This has reduced the mill’s gas consumption and slashed the 2018 CO2 emissions by an impressive 4,500 tonnes.” Wouter Lap, the mill’s MD, added: “What started as a pilot project has resulted in a modification of the mill’s steam system. At Smurfit Kappa we believe that the best ideas come from collaboration, creativity and being prepared to view our processes from different perspectives. This is a further example of how the Roermond paper mill is leading the paper industry in sustainable energy consumption.”
The steam integration project was showcased at the European Parliament as part of the Confederation of European Paper Industries’ (CEPI) To our roots and beyond - RE-INVEST 2050 scheme which aims to advance low-carbon innovation in the forest fibre and paper industry in Europe.
• Smurfit Kappa is also upgrading its flagship kraftliner mill in Piteå, Sweden, to increase the sustainability and efficiency of both its cooking plant and recovery boiler. Other work will include the installation of high-spec purification filters and an advanced combustion system. Piteå produces 700 kt/y of kraftliner. Smurfit Kappa is Europe’s top kraftliner producer.
