AB The use of wood and residual biomass from forestry works is a CO2 emission-neutralsource of energy that also contributes to reducing the risk of spreading forest fires, especially underMediterranean climate. The forest stands of stone pine (Pinus pinea L.) occupies about 0.7 millionhectares in the Mediterranean basin. In this study, the commercial quality of the pellets manufacturedfrom different types of cutting residues (needles and thin branches, medium branches and bark), aswell as wood from trunks and thick branches, was assessed. It was concluded that with the exclusiveuse of residual biomass it is not possible to obtain pellets of high commercial quality, useful forresidential or industrial use. However, the highest quality pellets could be obtained by combiningthem with stone pine debarked wood, but in a certain proportion that differs depending on the typeof residue (around 15% for bark, 30% for medium branches and less than 15% for needles and thinbranches). It is recommended to take advantage of both the thick wood (trunk + thick branches) and aproportion of medium branches and bark, while in the case of needles and thinnest branches it wouldbe more convenient to leave them in the forest for their incorporation into the soil, given their highnutrients concentration and their low quality for energetic use. The results found support a greatervalorization of the biomass obtained in the stone pine fellings. In the future it will be necessary tostudy which is the most appropriate logistics of the silvicultural works to be able to convenientlyapply the results of this study.
