Abstract

The heating value in two hardwood species and their lignin content had been carried out to determine the best species for woody biomass utilization in Amedi District/Duhok/ Kurdistan Region of Iraq. The study aimed to find out the relationship between the species, diameter of trees and the parts of tree with the heating value, lignin content, basic density and moisture content. 18 trees were felledand the number of samples were 54. The values of heating value ranged from 10.08 MJ/kg from the bark of a large diameter tree in Populusnigra to 22.69 MJ/kg from the branch of a large diameter tree of Quercusaegilops. The study revealed a significant differences in the means of heating value in species, classes, and parts of trees (P< 0.05). The mean of lignin was higher in the branchesfollowed by the wood and bark which gave close values. Accordingly, residual biomass, broken branches, limbs, and barks of trees are the best resources for aneffective utilization of woody biomass
