Pulping Process


The BCTMP (bleached chemi-thermomechanical pulp) process is a mechanical pulping technology which uses sodium sulfite for impregnation.

The BCTMP technology is used for both softwood and hardwood prior to the first refining stage. The fibers are bleached in a conventional peroxide bleach plant after refining and screening.
