“…The black liquor is commonly burned during the recovery process. The aim is to recover cooking chemicals and also energy (Saviharju 1993;Soares et al 2001). We assumed that the model state-of-the-art pulp mills produce enough electricity for their own operations by burning black liquor (Fibria 2010) and biological residues, like bark and sawdust (Sokka et al 2011).…”

“…Several gasification technologies were developed in parallel, mostly based on fluidized bed technologies. [96][97][98] During early parts of this century, however, the focus of related research changed toward the production of biofuels via Syngas upgrading. [11,99] This emphasized the need to move from airblown gasification to either oxygen-blown or indirect steam gasification, avoiding the presence of nitrogen in the Syngas.…”

“…Early on, the focus of black liquor gasification (BLG) research was on improving electricity generation efficiency via integrated gasification combined cycle (IGCC) applications. Several gasification technologies were developed in parallel, mostly based on fluidized bed technologies [96–98] .

Kraft lignin, a by‐product from the production of pulp, is currently incinerated in the recovery boiler during the chemical recovery cycle, generating valuable bioenergy and recycling inorganic chemicals to the pulping process operation. Removing lignin from the black liquor or its gasification lowers the recovery boiler load enabling increased pulp production. During the past ten years, lignin separation technologies have emerged and the interest of the research community to valorize this underutilized resource has been invigorated. The aim of this review is to give (1) a dedicated overview of the kraft process with a focus on the lignin, (2) an overview of applications that are being developed, and (3) a techno‐economic and life cycle asseeements of value chains from black liquor to different products. Overall, it is anticipated that this effort will inspire further work for developing and using kraft lignin as a commodity raw material for new applications undeniably promoting pivotal global sustainability concerns.
