LignoBoost is a complete system that extracts lignin, a component of wood, from Kraft black liquor. When a recovery boiler is the limiting factor to increasing pulping capacity, LignoBoost is a good solution to the problem. If 25% of the lignin in the black liquor is removed, boiler capacity can be increased to enable 20-25% more pulp production.
A well-spent decade of R&D
A joint project started in 1996 by Innventia (then STFI-Packforsk) and Chalmers University of Technology made major advances and, in 2003, the design principles of LignoBoost were verified. Mill pilot-scale trials led to a demonstration plant in 2007 that now produces pure lignin used as fuel on a large scale. Already supplying key components and recognizing its massive potential, Metso purchased the LignoBoost technology in its entirety in an agreement with Innventia that includes further development, design tool improvement and industrial up-scaling.
