First commercial LignoBoost plant to Domtar

Dec 16 2011  Metso will supply the world’s first commercial installation of LignoBoost technology to Domtar in North America.

The Lignoboost equipment will be intergrated with Domtar’s Plymouth North Carolina pulp mill. This order is an important breakthrough for the patented LignoBoost technology and provides the Plymouth mill with numerous benefits. The value of the order is not disclosed.The LignoBoost process separates and collects lignin from pulping liquor. Separation of a portion of the mill’s total lignin production off-loads the recovery boiler and allows an increase in pulp production capacity. The lignin recovered will be used for internal and external applications.The Lignoboost technology was developed by researchers at Swedish research company Innventia in cooperation with Chalmers university of technology in Gothenburg. The technology was later acquired by Gothenburg-based Metso Power Ab.The LignoBoost project is based on the 24 ton per day demonstration plant at Nordic Paper Bäckhammar mill in Kristinehamn, Sweden. The Lignoboost plant in Bäckhammar is owned and operated by Innventia since 2006.Domtar Corporation is the largest integrated manufacturer and marketer of uncoated freesheet paper in North America and the second largest in the world based on production capacity, and is also a manufacturer of papergrade, fluff and specialty pulp. The Company employs approximately 8,800 people. To learn more, visit www.domtar.com.
