Crane Invests in Sustainability

Crane Currency has inaugurated a new filtration system that will reduce water consumption by as much as 500,000 cubic meters per year and remove more cotton fibres for reuse in paper production at its paper mill in Tumba, Sweden.

The mill is located near two lakes in the Botkyrka municipality, approximately 20 km from Stockholm. The mill has long had well-developed processes for water purification and drying of paper. All wastewater from the plant is sent to a local treatment plant where the cotton fibres lost to papermaking are separated from the wastewater to end up either as fuel for biogas or as soil fertiliser.

As well as enabling Crane to significantly reduce its water consumption, the new 42 tonne filtration system’s capture of fibres will separate about 108 tonnes per year. The captured fibres can then be returned directly to the papermaking process.
