Valmet delivers LignoBoost XS plant for Mercer Rosenthal in Germany

Valmet Oyj’s trade press release on July 7, 2022 at 11:00 a.m. EEST

Valmet will deliver a LignoBoost plant for Mercer Rosenthal Lignin Center in Thuringia, Germany. The plant will extract kraft lignin from pulp mill black liquor. The extracted lignin will be used for developing various bio-based materials, which can replace fossil raw materials. 

The order is included in Valmet’s orders received of the second quarter 2022. The value of the order will not be disclosed.

"Mercer is investigating lignin utilization for biobased products as one of the alternate pathways towards utilization of side streams beyond biomass energy. With Valmet's Lignoboost pilot plant installation on-site Mercer Rosenthal will further build its solid lignin knowledge and will allow partnerships for product development. Valmet and Mercer Rosenthal have a long-lasting cooperation. As an example, in 1998, the mill was rebuilt to become Germany's first kraft pulp mill," says Wolfram Ridder, Vice President Business Development, Mercer International Inc.

LignoBoost XS™ has been developed for customers who want to enter the lignin business and start the production in smaller scale to enable full scale application development with future lignin customers. The plant offers Mercer the possibility to study different lignin qualities and their use in value-adding products. We have put special focus on designing the plant for safe and easy operation,” says Hanna Karlsson, Manager for Valmet’s Ash and LignoBoost Technology.
