Water consumption

Reduction in water consumption (m3 of water consumed/tonnes of final product) thanks to the implementation of a closed-loop water system that allows for reuse of water, where possible. (2009-2017)
Calculations show an improved 34.5% efficiency in water consumption in 2017, in comparison to the previous year, this is because Favini pays close attention to its water footprint. The aim is to continue investing in research and development so as to continue improving results.

What is water used for in a paper mill?

Water has multiple uses in a paper mill. Firstly, it allows for moving and distributing the fibres that form the structure of a sheet of paper. Dependent on the type of final product, differing amounts of water are employed.

Secondly, water is used in subsequent operations, including coating, a process aimed at improving the surface characteristic and enhancing the print quality of paper and board. Specifically, water used in coating can range from 60 per cent in the less diluted solutions and up to 95 per cent in more diluted versions.

Finally, water is also used during the drying process in the form of water vapour and is used only after being processed in a demineralisation plant.

In a paper factory water has multiple uses. It is used in the mixture, during coating and drying.

The impact of water management

Water management must take both environmental and economic impacts into account. The quality of purified waste water returned into water courses must be the highest possible standard to prevent any negative outcomes on the ecosystem.

Dutiful care throughout the entire process is therefore crucial and is constantly carried out through continuous chemical and physical analyses, all are aimed at assessing the quality of waste substances. All safety standards are carefully controlled on a daily basis.

Water management in a paper mill is not only crucial for the environment. In fact, the more water that is introduced into the production system, the higher the economic investments to purify it will be required. This is why supporting its reuse remains constantly fundamental.

Water saved in the past years thanks to an efficient use of this resource. (2009-2017)
Compared to the previous year, 2017 saw an improvement of 72% in terms of water consumption. This was a success, demonstrates just how strongly Favini believes in this sustainable journey.

Reduced consumption and improved efficiency of the purification system

To reduce waste and improve the factory’s efficiency, Favini has first of all made a distinction between the origins of its water dependent on its final use. For manufacturing Favini uses water from bore wells, while it uses water from mains supply for personal uses (from the canteen to restrooms).

A closed-loop water system has also been implemented in the paper mill: this allows for the reintegration of purified water from the plant, where possible. This recycling process, has led to significant savings.

Finally, waste water is processed in an effective, eco-friendly purification plant that allows for recovering water that, given its high quality, interacts respectfully with the ecosystem of the water courses into which it is returned.

The closed-loop system for the recycling of purified water and the eco-friendly purification plant together guarantee a more efficient process and reduced consumption.
