Influence of material origin on the size distribution of wood particles for wood-plastic composite (WPC) manufacture

This paper presents results from sieve analysis and image analysis-based particle size measurement (FibreCube) of wood particles for the manufacture of woodplastic composites. Wood of different origin (virgin Norway spruce, post-industrial particleboard residues, mixed waste wood) was used for particle manufacture. It was found that size distributions were different, although milling conditions were equal.
