Reduce water consumption per kg of linen delivered by Elis’ European laundries by 50% between 2010 and 2025
Terms of the action or commitment
2022 follow-up of the action
b) Numerical / Qualitative information
By the end of 2021, the Group has improved its water consumption per kg of linen delivered in its European laundries by 40%.
In order to reduce water requirements in its washing processes, the Group is identifying and implementing:
> good practices (e.g., optimizing the amount of detergent according to the actual weight of the textile)
> new technologies (e.g., type of detergent and activation, replacement of machines with more efficient ones)
> or transforming its washing processes (e.g., lower temperatures where possible, mixing reactive products under new conditions to increase their effectiveness).
The Group also favors the use of washing tunnels whenever possible. Equipped with separate compartments, they allow the linen to follow the different stages of treatment as it passes from one compartment to another and optimize water consumption.
In 2021, the Group continued to roll out programs to optimize its washing processes by changing products or dosages, in particular with emulsion detergent technology.
Elis also continued to roll out its program to replace washing powders with liquid detergents, which are easier to rinse and therefore save new water.
Lastly, the Group’s teams of “chemical, water and energy” engineers train production and maintenance teams at the sites in optimized washing methods (“essentials” of washing, making the best use of washing equipment, etc.).
Water is a strategic global resource and a real sustainability issue for communities, companies, and in particular for Elis with regard to its activity. Water is either taken from the natural environment (borehole water or surface water) or consumed by connection to municipal networks. The Group has been committed for many years to reducing its water consumption per kg of linen delivered. In France (the Group’s historical country), water consumption in Elis laundries per kg of linen delivered has been reduced by 49% between 2007 and 2021 and in Europe by 40% between 2010 and 2021.
