Oct 20, 2009. /Lesprom Network/. In October Iggesund Paperboard will begin using a new purification system that will further ensure the purity of the waste water from Iggesund mill, the company said in a press release received by Lesprom Network. Iggesund Paperboard, part of Holmen group, has invested just over Euro 25 million in chemical treatment that will complement the mill's current mechanical and biological water purification systems. "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."
