Title:
EUCALYPTUS BIOKRAFT PULPING PROCESS
Document Type and Number:
WIPO Patent Application WO1999046444
Kind Code:
A8
Abstract:
In a new process for preparing pulped wood chips for paper making, chips from a hardwood such as eucalyptus are inoculated with a living 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 kraft pulping with standard chemicals results in less chemical usage, reduced utilization of energy, improved strength, and reduced cooking time.
