Maryvale Mill Upgrade
In 2009 Australian Paper completed a major upgrade to the Maryvale Mill with an investment of over $600 million. This Pulp Mill upgrade expanded the Mill’s pulp production capacity by 22% and also delivered a range of quality, environmental, safety and health benefits.
The upgrade included the reconstruction of the wood yard to support the projected increase in production volumes. The rebuilt bleach plant is now producing ECF (Elemental Chlorine Free) Light Pulp, and has delivered significant improvements in emissions reduction, improved operational efficiencies which will include ongoing reduction of greenhouse gas emissions per tonne of paper produced as well as further savings in water usage and increased usage of renewable energy.
- Local production of ECF (Elemental Chlorine Free) Light pulp.
Reduced reliance on imported pulp and greater utilisation of local plantation fibre.
Enhanced consistency of wood supply to the new Pulp Mill. The improvements in the wood handling, chipping and sorting processes will maximise fibre quality and reduce wastage.
- Mitigating safety risks with the elimination of chemical storage areas and reduced handling requirements.
- Changes in operational processes provide a further reduction in a number of emissions including Total Reduced Sulphur (TRS) emissions and Sulphur Oxides (SOx) emissions.
- There has been a decrease in Chlorine compound emissions as a consequence of converting to ECF Light and adopting a low impact process and oxygen delignification.
- Reduced daily raw water inflows by 2.5% through efficiency innovations in manufacturing processes. Changes to water processes and replacing raw water with treated effluent in parts of the mill will result in a further saving of approximately 4ML per day.
Greenhouse Gas Emissions and Energy:
- Improvements in energy recovery from wood wastes and increased energy output from steam boilers continues to reduce our reliance on fossil fuels.
