LignoBoost - lignin from pulp mill black liquor

LignoBoost is a complete system that extracts lignin 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.

The first full-scale LignoBoost plant was started up in 2013 at Domtar’s Plymouth, North Carolina mill, where high-quality lignin is a by-product of the kraft pulping process. Domtar now market the lignin as BioChoice™ lignin. Click here for more information.

This installation is the result of a decade of well spent efforts: A joint project started in 1996 by Innventia (then STFI-Packforsk) and Chalmers University of Technology. The LignoBoost demonstration plant in Bäckhammar, Sweden, opened in 2007. For more information on this plant, click here.

Already supplying key components and recognizing its massive potential, Valmet purchased the LignoBoost technology in its entirety in an agreement with Innventia that includes further development, design tool improvement and industrial up-scaling.
