Water is an essential resource we all share. It's one of the most important natural resources in dairy production. We are focused on reducing water use and the amount of wastewater produced in dairy processing. We measure our water use and continually invest in new technologies that help us conserve.
FRESH WATER CONSUMED AND WASTEWATER GENERATED
We have been working hard over the past several years to systematically track and meter all of our water use and all of our wastewater and carefully analyze our water performance. Our Environment Health and Safety (EHS) managers in all Darigold plants have been working to identify and fix leaks, reuse water when possible, and develop process changes that reduce water consumption. These efforts have paid dividends by allowing us to reduce fresh water consumption overall by 2.7% and fresh water intensity (gallons of water per pound of milk processed) by 1.8% from 2011 to 2015. This represents true improvement, as our total product volume was essentially flat over this time period.
Between 2012-2016, WE REDUCED OUR TOTAL WATER CONSUMPTION BY NEARLY 3% AND OUR WATER USE PER POUND OF MILK PROCESSED BY ALMOST 2%.
Dairy processing technology is allowing us to conserve and reuse water in new ways year by year. Innovations we’ve invested in allow us to harvest water from the process of making different dairy products. This “polished water” resulting from milk drying processes is treated and reused several times for various plant cleaning purposes before it may be discharged into wastewater infrastructures. Instead of using more water as the amount of dairy products we produce has grown, we have invested in technology that makes the most and best use of the water required for production.
