This review paper describes the potential of developing a new lignocellulosic biorefinery concept integrated with the Kraft industry. To demonstrate that gasification is a sustainable and more valuable processing route than burning it in recovery boilers, additional processes of syngas cleaning and high sulfur recovery are required in order to achieve a significant reduction in operating costs to improve economic feasibility through BL gasification. BL gasification is performed using two types of gasifiers, one with a fluidized bed, which requires a higher air velocity to increase the yield of valuable products aiding to increase the calorific value of the produced gas compared to fixed bed gasifiers. Fixed-bed gasifiers produce gas with a high tar content because the heat and mass transfer between the gasifier and the biomass is low and non-uniform. BL gasification offers great potential for increased energy recovery with a reduced amount of emissions compared to that of conventional BL burning in recovery boilers.
