In October Iggesund Paperboard will begin using a new purification system that will further ensure the purity of the waste water from its Iggesunds Bruk mill. Chemical treatment will then complement the mill’s current mechanical and biological water purification systems. It has cost just over 25 million euro to make Iggesunds Bruk a peak performer in water purification.


“This new purification stage means we will be able to satisfy the environmental requirements that may be placed on us within the foreseeable future,” explains a satisfied mill manager Staffan Jonsson. “We’re reducing our emissions of nutritive salts like phosphorus and sulphur, which are particularly critical to the already eutrophic Baltic Sea. We’re also removing much of the brownish tinge that currently affects our waste water.”


Iggesund’s large-scale combination of biological and chemical purification is particularly out of the ordinary. Officials at the Swedish Environmental Protection Agency have followed the project and look forward to its upcoming evaluation.


“It is a very interesting combination of purification techniques and we’re very hopeful it will prove to be an effective method of reducing emissions from these types of forest industries,” comments Erik Nyström, senior advisor at the Swedish Environmental Protection Agency.


Iggesunds Bruk produces Invercote, a paperboard used in everything from book covers to packaging, both of which place crucial importance on design possibilities and colour reproduction. In many ways the mill’s environmental efforts already make it a model within the paper and paperboard industry. The facility already operates 95 per cent on bioenergy and plans to stop using any fossil fuels within the near future.


“Our vision is a mill that operates completely on biofuels and emits no carbon dioxide from fossil sources,” Staffan Jonsson says. “Our other air- and water-borne emissions will be at low levels that reinforce the leading position we already enjoy due to our product quality.”


He also emphasises the environmental significance of paperboard as a product. It is excellent for recycling either as a material or as energy, and its raw material, timber, is renewable.


“Paper and paperboard are already unbeatable materials from a sustainability viewpoint. This situation only improves when we can reduce the environmental impact of our production process, as we’re doing now.”


Jonsson and his colleagues at Iggesunds Bruk are continuing their work to gradually improve both the mill’s products and their sustainability.


“While our major competitive advantages are product quality and quality consistency, our sustainability work is more and more important to our customers,” he says.
