CHAPTER 4 Responsible management

The responsible use of water is integrated in all of our production processes through consumption reduction initiatives, maxi- misation of the reuse of water resources, the search for new sustainable sources of water and a decrease in our impact when water is discharged into the environment after use. We actively seek out and imple- ment the best techniques to ensure that

water capture and discharge to and from our facilities comply with the limits set in our operating licences and are respectful of the natural environment. Furthermore, in the design of new projects or prior to expanding existing facilities, we consider the issue of responsible water use and endeavour to implement the following measures:
