Non-wood is one of the most important raw materials for pulp and paper production in several countries
due to its abundance and cost-effectiveness. However, the pulping and papermaking characteristics of
canola straw have rarely been investigated. The objective of this work was to determine the potential
application of canola straw in the chemimechanical pulping (CMP) process. At first, the chemical composition
and characteristics of canola straw were assessed and compared with those of other non-woods.
Then, the CMP pulping of canola straw was conducted using different dosages of sodium sulfite and
sodium hydroxide. The results showed that, by applying a mild chemical pretreatment, i.e., 4–12%
(wt.) NaOH and 8–12% (wt.) Na2SO3, in the CMP pulping of canola straw, the pulp brightness reached
almost 40%ISO, and the strength properties were comparable to those of bagasse CMP and of wheat straw
CMP. The impact of post-refining on the properties of canola straw CMP was also discussed in this work
