Bogrundet - from oil to pellets
- Article
At the Bogrundet tree nursery in Timrå, SCA grows around 95 million seedlings every year. An efficient technical solution now supplies 14 greenhouses with pellet-based heating, replacing 430 cubic metres of oil annually.
At the end of 2020, the first part of the heating plant at Bogrundet was completed. Now two large pellet boilers supply 14 greenhouses with heat from bioenergy, in the form of pellets, instead of fossil oil.
"The investment in new heating means that we reduce our oil use by 430 cubic meters per year, says Thomas Vestman, head of the nursery.
The technical solution is based on a centrally located heating plant with two pellet boilers that are equipped with a flue gas purification system that reduces dust emissions to a minimum according to best available technology (BAT).
Via a district heating culvert consisting of insulated steel pipes, the heat is distributed to the 14 greenhouses and the hot water is distributed to 28 heat exchanger units. These aggregates are specially manufactured for Bogrundet's needs to provide the best effect in terms of heat and flow - all with the aim of making each forest plant grow as it should.
SCA's second nursery Wifstamo grows approximately 15 million forest seedlings per year. They have had fossil-free heating there for a long time, thanks to the ability to use district heating from Östrand's pulp mill.
