Jernforsen helps Vida utilise waste to power wood production facility

Jernforsen, part of Danish firm Linka Group, has upgraded Swedish wood producer Vida’s heating system to use wood waste left over from production.

The sustainable wood producer now only uses waste derived from production to heat both sawmills and drying ovens in the village of Nössemark in Sweden. The upgrade took place in collaboration with Jernforsen.

The city’s sawmill has been converted to heat the entire production – from premises to the drying oven – with the wood chips and bark that is left over from the production.

Vida’s new boiler for the plant is 5 MW and optimised to handle efficient combustion of the moist biomass, which contains up to 60% moisture. The whole plant has been developed and delivered by Jernforsen. In addition, the existing silo for bark and wood chips has been renovated, modernised, and connected to the new boiler. A new boiler house was built for the new system.

Jonas Axelsson, technical manager at Vida, said: “It is stable, simple, and reliable. For us, the most important thing has been to keep the schedule and get the facility we need, that is why we chose Jernforsen again and have received really good support when there have been challenges with managing the system.”

Today, Vida has boilers from Jernforsen at 10 of its 12 Swedish sawmills. They are designed to use waste from production and yields between 8 and 10 MW heat.

“For sawmills, it is important to be able to make the best possible use of their waste products,” Linka Group said in a statement.

“That is why we have done a lot to optimise and automate this type of plant, which runs stably in even the harsh environment on the border to Norway.

“Economically attractive energy plants with a focus on return on investment are not only a hit in Denmark.”
