Forest energy is predominantly produced from by-products of final fellings, such as treetops, branches and stumps and the small logs resulting from thinnings carried out for forest management purposes. In order to ensure a consistent quality, all logging residue heaps are covered with kraft paper, for example, and the site’s soil is prepared, following which the forest can be regenerated according to the owner’s wishes.
Stem chips are manufactured from small-diameter energy wood, but also from severely decayed or other wood material that cannot be utilised by the forest industry. The stem chips are even in size and quality.
Forest chips are Westas Bioenergy’s largest product in terms of volume.
