ABSTRACT
This paper presents the results of investigations on the suitability of MEA pulping of Sugarcane Bagasse (agro-biomass) for pulp and paper production. Objectives: To develop an Environmental Friendly Process Technology for converting Sugarcane Bagasse (Agro-wastes viewed as alternative raw material to wood) to pulp and paper. Method: Sugarcane Bagasse was characterized and properties like pulp yield, holocellulose content, lignin content, kappa number, viscosity, and brightness of the resulting pulp amongst others were determined. Excel 2016 was used to analyze the effect of operational variables otherwise known as the independent variables (i.e. temperature, cooking time, MEA concentration and liquid/solid ratio) and properties of bio-based material on pulp screened yield and strength properties of furnished paper (i.e. dependent variables) which include tear index, tensile index, burst index and folding endurance with errors less than 15% in all cases were determined. Influence of the independent variables in the pulping of Sugarcane Bagasse [viz. the effects that the MEA concentration (75%), temperature (150oC), time (90min.) on the yield and strength properties of furnished paper was investigated. Paper samples produced were tested for various strength properties. Results: The holocellulose (58.7%), α-cellulose (37.0%), and lignin (19.5%) contents are similar to wood materials, and various non-wood materials, but the fiber length is longer (1.7 mm). The MEA-cooking operation produced a pulp yield of 52.23% and a reject of 2.34% furnishing a pulp screened yield of 49.89%. The resultant pulp was subsequently bleached to a kappa number of 19.2 furnishing brightness level in the range of 90-94%. Conclusion and Recommendation: The physical properties, tear index (18 mN.m2/g), tensile index (86Nm/g), Burst index (5.9 kPa.m2/g) and folding endurance (97) recommend the cellulosic pulp from Sugarcane Bagasse obtained from the MEA process for strengthening the virgin fiber in recycled papers and also for developing certain types of printing and packaging papers. Kraft, soda and soda-AQ processes have been the most frequently used for softwood but in comparison to MEA-pulping process, higher yield at the same kappa number and better delignification without environmental damage due to lack of sulphur emissions was achieved. The Kappa number range (10.8-19.8), viscosity (290-820 ml/g) and brightness (81.5-93.2%) of these cellulosic pulp materials are appropriate for high-brightness printing papers.
Keywords: Sugarcane Bagasse, MEA-pulping; kappa number; Lignin; Kraft pulping, tensile index, Burst index.
