Customer case:

Stora Enso Sunila Mill - LignoBoost plant for high quality kraft lignin production

Stora Enso’s Sunila Mill produces kraft lignin with Valmet’s LignoBoost™ technology. The project started in 2013 and the plant was handed over to Stora Enso in 2015. In 2018, Stora Enso launched their dry lignin product, Lineo™ by Stora Enso, which is an excellent alternative to fossil-based raw materials in a wide range of applications.

I was impressed by the professionalism of Valmet’s project team. Even though Valmet had already built a similar industrial plant in the past, both parties knew from the beginning that this project would have a strong R&D nature.
