Ahlstrom currently has four business areas: Building and Energy; Filtration; Food and Medical; and Label and Processing.

To enable stronger focus on the filtration markets, the current filtration business area will be divided into two business areas: Transportation Filtration and Advanced Filtration.

As of 1 January 2013 Ahlstrom's business areas will be:

  • Building and Energy: materials used in wallcoverings, floorings and wind turbine blades (Ahlstrom produces glass fibre reinforcements used in the manufacture of the turbine blades);
  • Transportation Filtration: transportation filtration materials;
  • Advanced Filtration: life science and laboratory filtration materials; and
  • Food and Medical: materials used in teabags, food packaging, masking tape and medical gowns and drapes.

As announced earlier, the specialty paper business operated under the Label and Processing business area is planned to be combined with Munksjö AB and the transaction is scheduled to be completed in the first half of 2013. The Label and Processing business area will be reported as part of discontinued operations.
