Chemical composition of fired Aleppo pine (Pinus halepensis Mill.) sapwood

More recently in Croatia, as well as in the whole world, there are more and more issues with forest fires. After the forest fires, significant quantities of fired trees as a lignocellulosic biomass are left behind, and the question arises as to what degree they are chemically degraded or whether they still possess all the properties for further application in mechanical or chemical processing. According to that, the main aim of this study was to research the impact of low ground fire and high fire of the treetops on the Aleppo pine (Pinus halepensis Mill.) sapwood group chemical composition. The study was carried out by determining the group chemical composition of fired sapwood and nonfired for comparison with the fired, by sampling the rings at the height of the trees 0 m, 2 m 4 m. In addition, research results on group chemical composition of nonfired and fired Aleppo pine wood bark and sapwood from previous studies were used for comparison with sapwood from this study. The obtained results shows that the forest fires did not have any effect on overall Aleppo pine sapwood, where the fired wood bark take over all the damage caused by the high temperature during the forest fire.
