Various kinds of waste arise in the manufacture of Holmen's products. The vast majority of it is recovered or utilised as energy. The volume of waste sent to landfill has declined steadily since the year 2000, to the point where it now accounts for only around one per cent of the waste generated by Holmen's operations.


Holmen endeavours to minimise its quantity of waste and to utilise the highest proportion possible. Waste taxes and landfilling costs necessitate cost-effective management. Waste is separated into categories at all the units. Employees and contractors receive regular training in waste-handling procedures.

Current issues

Iggesund Mill

2015 saw a partnership with Stena Recycling AB, which has responsibility for all management of waste and recycling.

 

Over the course of 2015, Stena had a contract to purchase sediment (screened out fibres) from Iggesund Mill. Stena's responsibilities also include capping the oldest part of the mill's landfill. The 2015 phase proceeded according to plan.

 

Approved production waste (green liquor, ash, etc.) has been used as construction material.

 

A project to find long-term solutions for production waste is ongoing.

Hallsta Paper Mill

The ash previously created when biofuels were burned at the mill has been stored and is used as a construction material to cap the mill's own landfill. The ash is used under the sealing layer. Sludge collected from the mill's waste treatment system is used for soil products. This product is also partly used to cap the landfill. In 2015, small quantities of sludge were also used in external incineration trials.

Braviken Paper Mill

The amount of waste was significantly lower in 2015. The largest amounts of waste used to be generated in the recovered fibre process, in the form of sludge and plastic rejects. Braviken no longer manufactures de-inked pulp from recovered fibre, hence the fall in the amount of waste.

 

The amount of ash is also significantly down, since Braviken no longer incinerates recovered paper sludge, which had a high ash content.

 

Work to improve the sorting and management of internally generated waste continued in 2015. The labelling of the containers has been reviewed and improved to reduce the risk of incorrect sorting. Combustible sorted waste is now compacted at Braviken to reduce the volume of waste having to be transported.

Four categories

The by-products/waste that arise in production can be classified into four categories:

Combustible by-products/waste

Combustible by-products/waste that are mainly to generate thermal energy at the mills or in external heating plants.

By-products for various uses

Several projects have been carried out in recent years to find alternative uses for the by-products and waste that are produced. Some materials, for example sludge from wastewater treatment plants, can be used as a soil improver after treatment. Incinerator ash has been used as a road-building material and soil improver, and to cap landfills.

Waste sent to landfill

As a result of legislation and efforts to find alternative uses, the volume of waste sent to landfill has fallen to the point where, for many years now, it has accounted for less than 1 per cent of the by-products and waste generated by Holmen's operations.

Hazardous waste

Hazardous waste comprises materials such as waste oils, chemical residues and fluorescent tubes. Hazardous waste is dealt with by an authorised collection and recovery contractor. Certain fractions of the waste are recovered. Other fractions are destroyed under controlled conditions.

 

Oil-containing waste from docking ships is dealt with at port facilities at three Holmen mills. The waste is treated as hazardous waste. 


The Holmen Group

Holmen is a forest industry group that manufactures printing paper, paperboard and sawn timber and runs forestry and energy production operations. The company’s extensive forest holdings and its high proportion of energy production are strategically important resources for its future growth.
