This is a continuation-in-part of US Serial No. 884,513, abandoned. Neutral sulfite semichemical (NSSC) cooking of depithed bagasse gave pulp with improved physicomechanical properties for use in the production of newsprint paper. Thus, the NSSC cooking at 170-175/sup 0/ gave pulp in 70-75% yield. The NSSC pulp as above was bleached with alkali H/sub 2/O/sub 2/ at 50-70/sup 0/ to give a product with breaking load 8.7 kg, tensile 3.9%, breaking length 7.13 km, absolute tearing strength 135 cmg/cm, absolute bursting strength 3.8 kg/sq. cm and Elrepho brightness 61.
