The LignoBoost plant is integrated with the pulp mill and separates and collects lignin from the pulping liquor. This provides the Plymouth NC mill with numerous benefits. Lignin is a high-quality bio-based alternative to fossil fuel based materials. Separation of a portion of the mill's total lignin production also off-loads the recovery boiler, and allows an increase in pulp production capacity.
|Location||Domtar, Plymouth, NC, USA|
|Customer challenge||Converting a low value stream into potential revenue by separating lignin from black liquor.|
|Solution||The LignoBoost plant started up in 2013 and can produce up to 75 tonnes of high-quality lignin per day as a by-product of teh kraft pulping process. When the lignin is extracted, the load on the recovery boiler is lowered, enabling increased pulp production.|
|Results||Lignin can be utilized as renewable fuel replacing fossil fuels and as new bio-material for many industries. Increase of pulp production capacity by 5% and efficiency by off-loading the recovery boiler.|
