In this study, production of neutral sulfite semi-chemical (NSSC) pulp from
rapeseed was investigated. NSSC pulping experiments showed suitable cooking
conditions; liquor to rapeseed ratio of 10 : 1, chemical charge of 20% and a cooking
temperature of 170°C. Under these conditions, a total pulp yield of 66% was achieved.
Pulp was refined to freeness 350 and 400 ml CSF according to Canadian standards. 127
g/m2 handsheets from both pulps were made and strength properties measured. Statistical
analysis of results indicated that paper derived from freeness 350 and 400 ml CSF had
better strength properties in all indices in comparison with NSSC pulp from hardwoods.
