The investment in a new recovery boiler at the paperboard mill in Iggesund has significantly reduced emissions of fossil carbon dioxide and the target is to become self-sufficient in heating and electricity. As a result of extensive energy investments the paperboard mill in Workington currently runs on biofuel and is self-sufficient in electricity and thermal energy. In addition, fossil-free electricity is distributed to the local community. Today, the manufacture of paperboard in the Holmen Group is virtually fossil-free.
Major investments have been made at Hallsta Paper Mill to increase its energy efficiency, mainly through increased heat recovery from paper machines and pulp production. During 2014, emissions of fossil carbon dioxide decreased by around 70% compared with 2013. At Braviken Paper Mill, oil consumption has decreased due to improvements in the operational strategy for the mill’s steam system, greater efficiency in the solid fuel boiler and increased steam recovery from the production of thermo-mechanical pulp.
Together these measures have allowed Holmen to reduce emissions of fossil carbon dioxide by 45% in 2014, from 123 to 67 kilos per tonne of paper and paperboard products produced, compared with 2013.
Holmen is a forest industry group that manufactures paperboard, printing paper and sawn timber and runs forestry and energy production operations.
