WATER REDUCTION STRATEGIES Challenge PepsiCo Foods Canada’s (PFC) Resource Conservation (RC) initiative is focused on reducing consumption of resources like energy and water. The volume of water consumed by PFC’s manufacturing facilities varies based on product mix and the site’s local operations practices. Given the nature of our products, even the most water-efficient PFC sites can consume more than 100 million litres in a year. As part of PepsiCo’s global Environmental Sustainability commitment, we are working to reduce our water consumption by 20% per unit of product from 2006 to 2015, or 50% reduction vs. our 1999 baseline. Our ultimate goal, however, is to achieve water balance drawing little to no municipal water to manufacture our products. Strategy The results from our PFC Lean Six Sigma (LSS) and Kaizen program are prime examples of our water conservation mission. LSS plays a large role in the design of our water systems as well as helping us to identify areas of opportunity. An example of success is saving more than 40 million litres of water per year from a Sanitation Water Kaizen at the Cambridge manufacturing facility. Similar LSS water Kaizens are scheduled to be installed at each PFC manufacturing plant annually and further savings are anticipated at these sites. While reducing consumption is optimal, some of the best results PFC has achieved have come from water recycling technologies. The first, and most widely used system, is the Tsunami water recycling treatment system. This technology takes filtered water from our starch extraction system and injects a solution to manage organic loading in the water allowing us to reuse it in our process. The second system, called the Peeler Water Recycler, takes the water from our potato © PepsiCo Canada ULC, 2015 Did you know? potato peelers and mechanically filters it using hydro-cyclones so that it can be reused in the peelers, making the system a virtually-closed loop. With the ReCon program PFC has implemented many water saving ideas in its manufacturing facilities, including using Lean Six Sigma tools to find and improve water usage efficiencies in all operations. Examples of PFC’s water tactics include: The Cambridge manufacturing facility saves more than 90 million litres of water annually versus 1999 The final element of our long-term Near Zero Water initiative comes from the potatoes we use to produce our snacks. Potatoes naturally contain approximately 80% water by weight. When these potatoes are cooked, this water is released in the form of steam, which flows through our steam stack heat recovery systems. This water partially condenses within our heat recovery system heat exchangers today and is used in the food manufacturing process. Since it is essentially distilled water, further condensing the steam into water to use in the manufacturing process could be the key to food manufacturing with near zero municipal water. Reduced water consumption by more than 40% since 1999 per unit of food product Using Lean Six Sigma methods to reduce sanitation water usage Launched a water reduction best practice contest Enhanced water treatment at PFC’s largest Frito Lay plant in Cambridge, Ontario PFC has reduced water consumption by more than 40% per pound of product since 1999 Results The Tsunami and Peeler Water Recycler (PWR) systems have significantly reduced the amount of fresh water PFC consumes on a daily basis. The PWR system, installed recently at the Cambridge, Ontario facility, is expected to save more than 26 million gallons of water annually in combination with the Tsunami treatment system. The extra starch expected from the PWR system has the potential to generate additional revenues from the waste stream. These steps in water conservation and recycling will enable us to get closer to our goal of reducing water usage by 75% per unit vs. our 1999 baseline, and heading towards PFC’s ultimate goal of operating as water neutral.
