Metsa Fibre Modernizes Kemi Cooking to Raise Yield and Raw-Material Flexibility
ANDRITZ said Metsa Fibre will modernize the cooking system at its Kemi bioproduct mill in Finland, converting it to single-vessel LoSolids continuous cooking. The project is scheduled for fourth-quarter 2026 start-up and is intended to improve availability, cooking yield, raw-material flexibility and planned output at a mill producing up to 1.5 million tons of softwood and hardwood pulp per year.
Why it matters for converters and machine buyers: Better pulp yield and more flexible wood input can support more stable tissue and paper quality downstream, which directly affects slitting behavior, dust control and finished-roll consistency.
