Nestle Shows How To run A Dairy Factory With Waste Water

To celebrate World Water Day recently, Nestlé issued a press release describing the water conservation efforts of one of its factories in Mexico. The Nestlé dairy facility became the company’s first “zero water” manufacturing site in the world. Located in the central, water-stressed state of Jalisco, the factory turned off the taps completely, transforming its water consumption from 1.6 million liters a day to zero. The factory no longer draws water from the ground or water mains. It gets all its water from the milk it processes. It takes fresh cow’s milk – 88 percent water – heats it at low pressure to remove some of its water content. The steam is condensed, treated and used to clean the evaporating machines. The water is collected again, purified and recycled again. [ Dairy factory in Mexico, image credit © Nestlé ]
