Abstract
There are important consequences for a pulp mill when either new or traditional technology is integrated into the production system. When a flexible technology, such as lignin removal, is introduced into the production system many new opportunities will arise, therefore, it has to be decided what needs to be achieved in the initial phase of operation and what the next step will be to improve the lignin value and the overall value for the pulp mill. The focus of this work is mainly on changes in the power balance and improved use of the wood source as a biofuel when the LignoBoost process is installed in a greenfield mill for production of Eucalyptus urograndis market pulp.
