Interest and commercial activity in lignin production continues to advance in North America.

Domtar has begun construction of a kraft lignin precipitation plant at its Plymouth, NC mill, which will use the Lignoboost technology supplied by Metso. It is scheduled to be in commercial production early in 2013.

In a separate development, the Liquid Lignin Company has announced a competing process for precipitation of lignin from kraft black liquors. The technology maintains the system under elevated temperature and pressure to avoid loss of heat during precipitation and filtering of the lignin. A pilot plant is under construction and a prototype capable of producing 3 - 6 ton/day is planned for 2013.
