2.3.4. Structural Properties

Structural analyses were performed on lab-scale pellets using an optical microscope Nikon LV 100 at 50× in reflection.

All the described analyses were run in triplicate, except where indicated diversely. Averaged results were compared with the standard values established in the non-woody pellet norm (UNE-EN ISO 17225-6) [24]. Table 1 gathers the most representative properties used in this study.
