Kraft Process - an overview | ScienceDirect Topics

The Kraft process relies heavily on lignin itself as fuel to operate the relatively expensive chemical recovery boiler system. Consequently, it is unlikely for the lignin produced from the Kraft process to be largely used in commercial markets or in biorefinery operations for the production of high-value chemicals (PNNL, 2007).
