Bioenergy from forestry

The extraction of slash (branches and tops) is preceded by a so-called slash-adapted felling, where we place branches and tops in piles beside the harvester's tracks while the trees are being felled.

After the slash has dried for a summer at the clear-cut, it is transported to the roadside. The piles are covered with paper and chipped during the heating season.

We deliver slash to our customers, either in the form of chips or as loose slash (unchipped).

Drier volumes of slash chips and roadside clippings can be used to mix with wetter fuels to achieve better dry matter content.

Slash chips are used as fuel in larger boilers and work well in both grate and fluidized bed boilers.

Slash chips typically have a moisture content of about 35-50%, an energy value of approximately 2.5 MWh/ton, and an ash content of 1-2%.

temwood chips are chipped fuelwood – logs that cannot be processed at the sawmill or used in pulp production.

Stemwood chips are burned in both larger and smaller boiler plants. They are often mixed with, for example, bark volumes to help improve the dry matter content and provide better combustion.

The normal moisture content of stemwood chips is 40-50%, and the energy value is approximately 3 MWh/ton.

Forest fuels from roadside cutting. During cutting, the material is sorted, with the larger trees going to pulp production and the remaining becoming fuel.
