Sunila takes over operation of LignoBoost
Stora Enso is now running the Valmet-supplied LignoBoost lignin separation plant, the second commercial scale LignoBoost plant in the world, at Sunila mill.
- Through the lignin extraction process we have replaced a great amount of natural gas with the dried lignin produced in the new LignoBoost plant, and by doing that reduced our carbon dioxide emissions, says Sakari Eloranta, Senior Vice President, Operations and Investment Projects, Stora Enso Biomaterials.
- We continue to develop this technology, as we see a great potential in utilizing lignin in various uses. Lignin powder can be used as raw material at the mill for firing or it can be converted into other materials and products. Lignin separation will at the same time improve the environmental performance of the mill, says Anders Larsson, director, Bio materials, Pulp and Energy business line, Valmet.
LignoBoost is Valmet's patented method of extracting lignin from Kraft Pulp process' spent cocking chemicals, the black liquor.
