One is a treatment plant for water discharges and the other a steam boiler. The plant uses the multibio treatment system, where bacteria consumes pollutants in several stages before leaving the mill with the water waste. It will reduce the discharge of harmful CODs, or chemically oxygen consuming substances, by 60%.

The steam boiler was built using the mills old unused recovery boiler and is fuelled by surplus bark from the production process. Existing electrostatic precipitators have been reconstructed to reduce the impact of dust discharge.
