Braviken Paper Mill produces MF Magazine, book paper, newsprint and coloured newsprint from thermo-mechanical pulp (TMP). The mill is located alongside Bråviken, a deep bay in the Baltic Sea with good water turnover.


Environmental activities in 2017

All limits for emissions to water and air as set out in Braviken's environmental permit were complied with in 2017. The guideline values for emissions to water of organic material (COD), suspended solids (SS) and phosphorus (P) were exceeded in February and March. No complaints about the site were made by the public and no disruptions to operations or similar incidents occurred on the site that could lead to adverse effects on people and the environment.

To improve water treatment, Braviken carried out a project in which two part-streams of the process water are treated in a closed existing microflotation unit in the mill's recovered paper plant. Organic matter (COD) is removed by microflotation, part of the process water is re-used in the process and another part is conveyed to the Braviken water treatment plant. Both a reduced level of organic matter (COD) and a reduced flow rate to the water treatment plant have led to more effective water treatment. The equipment was taken into use in March 2017.

In order to further improve Braviken's water treatment, work began on replacing five surface aerators in the biological treatment stage with new ones that have a better oxygenation capacity, which is expected to lead to even greater reduction of organic material (COD). The work is scheduled for completion in the first quarter of 2018.

Braviken has spent many years minimising its combustion of oil, and has brought its oil consumption down from around 25 500 m3 in 2005 to around 5 500 m3 in 2017, representing a cut of approximately 80 per cent. The fall in oil consumption is largely attributable to improvements in the operational strategy for Braviken's steam system, greater efficiency in the solid fuel boiler and increased steam recovery from the production of thermo-mechanical pulp. The mill's steam and heat needs can now usually be covered by steam recovery from the production of thermo-mechanical pulp and from the combustion of biofuel. Braviken's oil-fired boiler is primarily used during shutdowns of the solid fuel boiler for maintenance.

Energy integration between the mill and nearby Braviken Sawmill was implemented in 2010, making it possible for the mill to meet the sawmill's heat energy needs. The sawmill supplies chips to the mill that are used in the production of paper, which cuts down on the need for transport, among other benefits. The sawmill also supplies the mill with biofuels.

Permits for operation

Braviken Paper Mill holds a permit for its operations granted under the Environmental Code in 2002.

Braviken Paper Mill applied for and was granted a temporary change to its conditions for COD during 2017 and 2018. Water treatment measures will be carried out in 2018.

The mill also has a water judgment from 1975 concerning its sourcing of raw water from Motala Ström.

The mill is covered by the rules on fossil carbon dioxide emissions trading, under which it holds a permit for carbon dioxide emissions and has been allocated emission allowances for the period 2013–2020.

Since the 2015 Environmental Report, the mill's outcomes and status have been reported in relation to current BAT conditions.

Environmental certification

The environmental management system has been certified to ISO 14001 since 1999.

The energy management system has been certified to ISO 50001 since 2012. Before that, the energy management system had been certified to SS 62 77 50 since 2006.

The health and safety management system has been certified to OHSAS 18001 since 2015.

Braviken Paper Mill has held chain-of-custody certification for wood raw material since 2008.

In 2013, Holmen Paper had its graphic paper approved to carry the EU Ecolabel. Products awarded the EU Ecolabel meet the ecolabel's criteria concerning the manufacturing process in terms of certified wood raw material, chemical consumption, energy consumption and emissions to air and water.

Braviken's products fulfil the requirements for Nordic Ecolabelling of paper products.

Disruptions to production and complaints

The guideline values for emissions to water of organic material (COD), suspended solids (SS) and phosphorus (P) were exceeded in February and March. Measures to improve water treatment have been implemented. No complaints concerning the mill's operations were received from the public.

Investments/environmental and energy measures

Re-routing of pipes in order to be able to treat partial flows of the process water in the closed existing microflotation unit in the mill's recovered paper facility. The equipment was taken into use in March 2017.

In order to further improve Braviken's water treatment, work began on replacing five surface aerators in the biological treatment stage with new ones that have a better oxygenation capacity, which is expected to lead to even greater reduction of organic material (COD). The work is scheduled for completion in the first quarter of 2018.

Follow-up of environmental and energy targets in 2017

Braviken is to help reduce emissions of fossil carbon dioxide. Braviken has a target for 2017 of limiting oil consumption to a maximum of 3 000 m3. Oil consumption for 2017 was around 5 500 m3 and the target was not achieved. This was due to more shutdowns of the solid fuel boiler (wood fuels) for maintenance than planned. During shutdowns of the solid fuel boiler for maintenance, the mill's oil-fired boiler was used.

Braviken had a target for 2017 to bring specific electricity use for the production of paper down to 2.7 MWh per tonne of paper, excluding the electric boiler, which equates to 1 per cent less than the budgeted electricity use. The target was not achieved. The specific electricity use for the production of paper was 2.8 MWh per tonne of paper in 2017.

Planned environmental and energy measures in 2018

Work on minimising the use of oil to meet the mill's steam and heat needs will continue into 2018. A considerable portion of the mill's steam and heat needs will be covered by steam recovery from the production of thermo-mechanical pulp and from the combustion of biofuel.

There are plans to continue optimising steam production during periods of low steam demand (summer months).

Environmental and energy targets in 2018

Braviken has targets relating to areas including energy efficiency and oil consumption. Braviken has managed to reduce its oil consumption and the mill continues to focus on keeping its oil consumption low. The energy targets are intended to reduce the use of electricity and heating and to increase heat recovery.

Braviken is to help reduce emissions of fossil carbon dioxide. Braviken has a target for 2018 of limiting oil consumption to a maximum of 3 000 m3.

Braviken has a target for 2018 to bring specific electricity use for the production of paper down to 2.8 MWh per tonne of paper, including the electric boiler, which equates to 1 per cent less than the budgeted electricity use.
