This study was conducted on the branches of trees growing in the Dibs Forest/north of Kirkuk city. (Eucalyptus camaldulensis, Populus euphratica, Populus alba, Populus nigra, Platanus Oreintalis, Platanus Orientalis, Salix alba and Dalbergia Sissoo) where the study samples were taken from the lower branches of the trees, and samples were taken from the main trunk of the trees for comparison purposes. The technological characteristics studied included the morphological description of the branches and anatomical characteristics (length and diameter of fibers, diameter of Lumen, thickness of cell wall, Rankel ratios, Slendeness and flexibility coefficient) and chemical characteristics (percentage of soluble extracts, lignin, ash and Holocellulose) in addition to measuring density as a physical characteristic. It was not possible to measure the mechanical characteristics of the empties due to the significant twisting and lack of straightness.
Data varied within the studied species. Anatomical characteristics in branch wood showed a decrease in values, while the percentage of Holocellulose and density values increased in tree branches. Branch wood can be used in the manufacture of cellulose pulp and medium-quality paper, as well as in the production of composite panels.
