The need for pulp and paper currently in the whole world has become shooting up massively. The generation of the pulp, as well as paper from woody materials, has a challenge due to deforestation, huge chemical and energy consumptions. Now, an alternative source for paper is lignocelluloses wastes, because of low cost, low energy, and chemical consumption. Among them, the banana pseudostem was best for the input of pulp and paper production. This investigation was on the production and characterization of pulp from Banana Pseudo Stem for Paper Making via Soda Anthraquinone pulping process. The amount of cellulose (41.45%), ash (12.4%), hemicellulose (23.37%), extractive (12.72%), and lignin (10.46%) contents were obtained at the initial compositional evaluation of the pseudostem. It has excellent fiber length (1.75mm), fiber diameter (22.15μm), an acceptable Runkle ratio (0.55), and flexibility coefficient (159.64). The effect of temperature (130,140 and 150 °C), cooking time (45, 60, and 75 minutes), the concentration of soda (10, 12.5, and 15%), were examined. The maximum pulp yield and kappa number was 36.7% and 22.8 respectively obtained at 10% of soda concentration, at 150 °C, and 63 minutes of cooking time from oven-dried raw material. The produced paper from the banana pseudostem has a tensile index, tearing index, smoothness, and porosity were 78.75 Nm/g, 19.1 mN.m2/g, 500-530μm, and 50 sec/100ml air respectively. This study indicates that high strength mechanical property and good surface properties paper can be produced from banana pseudostem pulp with a more environmentally friendly pulping process. |
