"Moringa oleifera (drumstick) wood was evaluated in terms of its chemical composition, morphological features, Kraftpulping behavior, ECF bleaching and mechanical strength properties – important parameters for pulp and paper making– in comparison with Acacia mangium. Moringa oleifera was found to have the following composition: holocellulose65.5%, lignin 20.5%, pentosan 11.6%, -cellulose 40.5% and extractives content of 5.15%, which made it comparablewith the Acacia mangium wood sample. The alkali prehydrolysis of Moringa oleifera was carried out using 2% NaOHat 150 °C. The prehydrolysis liquor (PHL) was found to contain 50.9 mg/kg of calcium, 5140 mg/kg of potassium and312 mg/kg of iron content. The prehydrolysis step was followed by Kraft pulping in order to obtain chemical gradepulp of kappa number 15-16 under optimized conditions. The Moringa oleifera pulp was bleached using the DEpDbleaching sequence to reach 85% brightness (ISO). The bleached pulp had an average fiber length of 1.21 mm, whichwas higher than that of Acacia mangium – 0.782 mm. The mechanical strength properties of the unbleached andbleached pulps, such as tear, tensile and burst indices, were also determined to show their suitability for pulp and paperproduction."
