Feb. 16, 2023 - Stora Enso and Valmet have started collaborating on next-generation lignin product and process development to drive Stora Enso's lignin-based businesses and further improve the performance of the Valmet LignoBoost technology.

The objective of the partnership is to further develop the quality and customer value of lignin, increase the supply by optimized process machinery and asset design, and to accelerate the speed of meeting the growing lignin demand of the future.

"We are developing our lignin offering to be able to meet the growing need for lignin and tailor it for our customers working with various end-applications. With next-generation lignin, we can, for instance, enable the development of sustainable battery technologies," says Kimmo Ruohoniemi, Head of Lignin Operations at Stora Enso.
