Iggesund Mill is located just south of Hudiksvall on the Iggesundsfjärden bay. The mill produces high quality solid bleached paperboard for packaging and graphics printing. A few kilometres north of Hudiksvall lies Strömsbruk, where paperboard from both Iggesund Mill and Holmen’s mill in Workington is laminated and plastic coated. Skärnäs Terminal belongs to Iggesund Mill and is located next to the mill.

Environmental activities in 2015

One of the focus areas for environmental activities in 2015 has been energy generated from biofuels. Through a carefully considered operational strategy and active allocation of available biofuels, over 98 per cent of total steam production derived from biofuels. 

Iggesund Mill had problems with the dewatering of sludge in wastewater treatment in 2015, with the result that the limits for discharges to water were exceeded for some parameters. Iggesund Mill has worked hard to find a solution to this problem. 

Several energy-saving measures were decided upon during the year. The annual energy saving from these measures is estimated to be around 35 GWh.

Permits for operation

The company's operations (Iggesund Mill excluding Strömsbruk and Skärnäs Hamn) are subject to the Land and Environmental Court's decision of February 2013. 

The coating and laminating plant at Strömsbruk has been classified as a 'C' plant with an obligation to notify its environmental activities to the authorities since 2007/2008. 

Permits under the Environmental Code for the port operations at Skärnäs Terminal, Iggesund, were granted in 1999. 

The company is covered by the rules on fossil carbon dioxide emissions trading. It holds a permit for carbon dioxide emissions and has been awarded emission allowances for the trading period 2013–2020. 

Iggesund Mill intends to apply for a new permit for expanded production in 2016. The operations at Strömsbruk and Skärnäs Hamn will also be included in this permit.

Certified environmental and energy management systems

Iggesund Mill's environmental management system has been certified to ISO 14001 since 2001. The energy management system was certified in 2005, and this system was upgraded in line with ISO 50001 in 2011. The company also has both FSC® och PEFCTM certification for the wood raw material. 

The production unit at Strömsbruk and Skärnäs Terminal are covered by all certifications.

Investments/environmental and energy measures

The drying machine for pulp was rebuilt and fitted with a shoe press. The action taken on the drying machine is estimated to result in an energy saving of around 20 GWh. 

The production line for softwood sulphate pulp was upgraded in 2015, and further action is planned in 2016. The wash press and diffusors have been upgraded. These actions will lead to a saving in water consumption and a reduced load on external wastewater treatment. The major positive environmental effects are expected to become apparent after the 2016 measures have been implemented. 

A preliminary project on recovery of precipitation chemicals from the external wastewater treatment process was carried out in 2015. A final report is expected in the first half of 2016.

Disruptions to production and complaints

Iggesund Mill is focused at all times on designing out risks that could cause environmental incidents. A number of incidents with an environmental impact occurred in 2015, one of which necessitated written notification to the supervisory authority. This incident related to a small quantity of liquor that entered a receiving body of water. 

In terms of conditions for emissions to air, the company respected these during the year. In terms of discharges to water, the limit for suspended solids and TOC on an annual basis was exceeded. This was principally due to problems with the dewatering equipment in wastewater treatment. Iggesund Mill informed the supervisory authority and is working hard to address the problem. The investigation is expected to continue during the first half of 2016. 

Two external complaints were received during the year. One concerned odour and one related to foam from the mill's aerated pond. The complainants were informed about the underlying causes.

Follow-up of environmental and energy targets in 2015

The aim is constantly to reduce environmental impact, with the vision of creating an operation without fossil carbon dioxide emissions. 

Iggesund Mill follows this up with two key indicators. 

  1. Biofuel-based steam production – target level 95 per cent
  2. Back-pressure production – 34 GWh/month

The target level for biofuel-based steam production was attained. The outcome was 98.1%. 

The target level for back-pressure production was not met. The outcome was 24 GWh/month.

Planned environmental and energy measures in 2016

The production line for softwood sulphate pulp will be further upgraded in 2016, leading to a reduced flow to water treatment. 

In addition, in 2016 the company will apply for a new environmental permit for expanded production. This will lead to several studies of environmental and energy measures.
