Although due to the type of activity of supermarkets, the consumption of water in their stores, logistics platforms or offices is not significant, especially in comparison to industrial and agricultural consumption in their supply chain, we still want to evaluate with this question whether These companies apply gray water recycling methods as a result of a corporate and responsible policy regarding the use of this increasingly important and threatened natural resource.

In this sense, what we value with this metric are the initiatives in the matter of water recovery, such as retention of rainwater for irrigation as we have verified that Mercadona and Lidl carry out or the promotion of green buildings in Aldi Germany that reduce the demand for drinking water by recycling wastewater and using local resources



Although the water consumption of supermarkets in their facilities is much less relevant, we do want to evaluate also with this question if they apply gray water recycling methods as a result of a corporate and responsible policy regarding the use of water

In this sense, the recycling of wastewater plays a determining role. Through the application of different purification and treatment processes, it is possible to ensure that used water is not wasted, reducing the risk of environmental contamination and allowing companies to opt for benefits such as reducing costs or increasing operating efficiency.
