The investment will also lead to large parts of the mill's energy system being rebuilt, which will increase energy efficiency significantly. The detailed planning work has begun and the new biofuel boiler will be completed and put into use around mid-2017.
Rottneros Mill produces two different kinds of high yield pulp for paper producers, CTMP and groundwood pulp, and has for many years used oil to dry the pulp.
When the new biomass boiler is completed, the biomass will replace all oil used today, and the mill's energy consumption will thus be entirely fossil-free. The new biomass boiler has an effect around 18MW and will replace an older biomass boiler. Supplier of the new boiler will be selected in the near future.
“When we're now investing in a new biofuel boiler, we will also optimize and rebuild our energy system at the mill. It will result in significant energy efficiency improvements and environmental benefits in terms of lower emission levels. The extents of the savings are at least SEK 25 million ($2.9 million) per year,” says Olle Dahlin, CEO of Rottneros Mill.
