Vallvik Mill produces and develops the chemical long-fibre pulp Robur Flash ECF.
The wood is heated with white liquor in a boiler to separate the fibres from the lignin. The pulp is washed, screened, bleached and purified. It is then flash-dried so that the fibres adopt an open structure. Finally, the pulp is pressed into 200kg pulp bales. The lignin from the wood is used as fuel in the factory and about 97% of the chemicals are recycled.

The pulp’s high quality, purity and filtration capacity make it an ideal choice for air filters in the automotive industry and bleached liquid filters for food.
