A high end-product quality with low effluent flows and high environmental performance will be secured with the latest generation of Valmet TwinRoll wash presses throughout the fiberline in combination with Valmet´s screening, oxygen and bleaching technology. Valmet Fiberline Analyzer and measurements for fiberline control are also part of the delivery. The fiberline will have a capacity of 600,000 tonnes per year.

The delivery for the recovery island includes a Valmet Recovery Boiler and Ash Crystallization. The high-power recovery boiler is designed for long lifetime and long campaigns between cleaning shutdowns. The boiler will have a capacity of 3500 tonnes per day. The high-power features will enable higher renewable electricity production for mill's own use.
