PepsiCo has come up with a novel plan to reduce the water consumption in its factories. It aims to recycle the water extracted from potatoes to run its potato chip plants in the UK. 80% of a potato is water and PepsiCo uses around 350,000 tons of potatoes annually.
Walter Todd, PepsiCo’s Vice President of sustainability for Europe said in an interview to The Guardian that in the process of cooking the potatoes, water is boiled off and lost, so the challenge for them is to find how to capture that water and use it in their operations, thus conserving the water from the mains. He says, within 10 years, they plan to source all their water for the four crisp factories in the UK from these potatoes, thus taking them off the water mains completely.
