The aim of this work is to investigate the influence of the main densification parameters (moisture content, compression and temperature) and raw material (leaves, pruning, and wood) on the quality properties of pellets from the different olive tree pruning residues. In general, low moisture content (9%), short compression lengths (20–24 mm) and temperatures higher than 40 °C were the best pelleting conditions for the residual biomass from olive trees, although these parameters varied between the raw materials analyzed.
