During debarking, sawing, cutting, and planing in the sawmill industry, energy-rich materials are produced. They become biofuels for both large and small heating facilities.
Between 5-15% of a log's volume is bark. Debarking occurs at sawmills and pulp mills.
Due to its high moisture content, bark works best as fuel in boilers with an output of over 5 MW. Bark is suitable for both grate and fluidized bed boilers.
The moisture content of the bark varies depending on the season, but on average it is around 55%. The energy value is approximately 1.9 MWh/ton and the ash content is 1-3%.
Bark that falls off logs and pulpwood in storage areas is collected and processed.
The collected bark is mainly used for combustion in larger boiler facilities and as a fuel to mix with others.
The moisture content is between 55-65% and the energy value is approximately 1.7 MWh/ton.
When dried and sawn planks and boards are cut to the desired length, trimming residues are produced. These are chipped, creating a fuel with a very high dry content.
Dry chips can be used as the sole fuel in smaller boilers under 2-3 MW, as a mix with wetter forest fuels, and as a raw material for pellet production.
Dry chips have a moisture content of only 12-14%. The energy value is around 4.5 MWh/ton and the ash content is 0.3-0.7%.
When dried timber is further processed through planing or milling, planer shavings are produced.
The planer shavings are mainly used as raw material for pellet production in Stugun and Rundvik.
Planer shavings typically have a moisture content of 10-13%, an energy value of approximately 4.5 MWh/ton, and an ash content of 0.3-0.4%.
We manufacture wood pellets from sawdust and planer shavings from the sawmills. When the sawdust is dried and pressed into pellets, it becomes a fuel with high energy value and consistent moisture content.
Wood pellets can be burned in stoves, residential burners, and large heating plants.
Energy value: at least 4.9 MWh/ton, less than 0.5% ash content, 7% moisture content.
We can see growth and business opportunities in wind, bioenergy and biofuels. Rising demand for renewable and climate-friendly energy combined with the need for alternatives to oil and gas provide us with good potential to make a further contribution to the energy transition – by providing and developing sustainable energy.
There is an urgent need to change our society – and we have a clear picture of how to achieve this. We see a green transition, with an economy that works for both people and the environment. We see a transition to products that do not damage nature, but are instead part of the perpetual cycle. We see sustainable investments and innovations. The forest is showing the way to a fossil-free world in balance.
