Evaluation of possibility of obtaining woodchips from wood residues

Abstract

For the moment, the priority for the development of forestry is the provision of continuous, non-exhaustive and rational use of forest resources. In spite of this, logging residues, i.e. brushwood, twigs, tree tops, butt end and cull wood, which are unavoidably formed due to logging processes, are ploughed and burned. Analysis of this type of logging debris showed that logging residues are up to 18% of the total wood biomass and they are potential raw materials for obtaining woodchips for fuel and other types of products. The study presents evidence-based and experimentally confirmed possibility of obtaining woodchips for fiber board, pulp and paper industry. The influence of the wood species and the type of logging residues on the quality indicators of chip was established.
