The recycled cartonboard that we receive gets ground and sent into a 40 metre long drum. By adding plain water, the drum separates plastic from paper fibre in, for example, milk packaging. The paper fibre becomes raw material in our board production while the plastic is incinerated in our energy plant along with other bioproducts.
Our packaging board consists of four layers with different characteristics. Once the stock has been put into the four layers, it is compressed. Subsequently, the board is dried with the help of steam from our energy plant and finally coated to obtain a bright and even surface.
In the finishing stage, the board is cut into sheets or smaller rolls depending on the customer’s preferences. The trimmed sheets are then placed on pallets, packaged and fitted with labels. Just to be sure, we conduct quality checks at several stages during the process.
In the finishing department there is also an extrusion laminating machine. The extruder coats the board with polyethylene or a metallised polyester foil for protection against possible fatty and moist contents within the carton.
Fiskeby’s biogas plant produces climate-neutral biogas from process waste water. The new biogas plant came into force in 2015 and relieves our other water purification plant. The increased purification capacity reduces our environmental impact and provides potential for extended packaging board production.
A new solid fuel boiler was inaugurated in Fiskeby in 2010. The boiler provides all the steam used in the production of our packaging board and about 30% of our electricity needs. The fuel consists of 40% reject, 45% industrial waste and 15% recovered wood fuel.
