Eucalyptus biomechanical pulping process

摘要

In a new process for preparing pulped wood chips for paper making, chips from a hardwood such as eucalyptus are inoculated with aliving culture of one or more white rot fungi. The fungi propagate throughout the body of the wood chip, selectively attacking the lignin of the wood without harming the cellulosic fibers. Subsequent mechanical pulpting results in reduced utilization of energy, improved strength, and reduced cooking time.
