ABSTRACT: Morphological characteristics and proximate chemical analysis of E. binata showed it as a suitable
raw material for writing and printing grade paper. Maximum pulp yield (43.58%) of kappa number
17.38 with 0.9% screening rejects was obtained at 12% of active alkali (as Na2O) pulping
temperature 130°C, cooking time 120 min and solid to liquor ratio 1:4. During bio-soda pulping of E. binata, pulp yield decreased slightly while pulp brightness, tensile index, burst index and double
fold numbers were improved by 4.1%, 24.94%, 14.03% and 48.45% respectively compared to soda
pulping. During ethanol-soda pulping of E. binata, pulp yield, pulp brightness, tensile index,
burst index and double fold numbers were improved by 3.9%, 6.6%, 32.18%, 35.40% and 77.31%
respectively compared to soda pulping.
