Listen to Ed Pinero discuss how to calculate the ROI of water savings.
In the 1960s, a biochemist named Joseph Owades discovered a way to reduce the calories in beer through the removal of starch, producing the world’s first low-calorie beer. 50 years later, beer companies are still looking for light alternatives, only this time they want them to be sustainable, aiming to make the entire brewing process “water-lite.”
With more than 150 years of experience under its belt, Heineken International is no stranger to these trends. The international brewing company wants to reduce its water consumption by 25% by 2020, and to help meet their goal, they worked with Veolia Water Technologies to provide a custom water recovery system at Heineken’s cider mill in Hereford, UK. This mill is the biggest in the world, providing real opportunities to impact sustainability.
Highlights of the sustainable system include:
-- Heineken used Veolia’s RecoBLUE online calculator to discover that they could recover 50% of the reverse osmosis losses out of a total of 30 m3/h of water that was not being utilized.
-- Veolia specially configured Heineken’s Sirion™ Mega Recovery RO Unit to ensure that the water recycling process didn’t increase energy and chemical consumption. This unit doesn’t require additional chemical dosing, reduces energy consumption and minimizes the plant’s carbon footprint.
-- Veolia’s RecoBLUE calculator was used to provide projections of water loss that could be used as benchmarks.
The new system is brewing up great results so far, reducing water use by more than 130,000 m3 per year. The annual savings will cover capital costs in less than four years, proving that watching water consumption isn’t just sustainable, it’s good for the financial waistline.
