Frito Lay Reuse Plant, Arizona

What is it?

A potato chip manufacturing facility at Casa Grande in Arizona with a "net zero" environmental footprint. Wastewater from the manufacturing process is reused as rinse and wash water and made available for irrigation. The project also includes a biomass boiler and a solar power system.

Who is responsible?

GE Water, using a Zenon ZeeWeed membrane bio-reactor.

What makes it special?

• The system delivered a 90% reduction in both water and energy usage at the plant.

• The food processing sector has been reluctant to embrace water reuse. This project sets the standard for water sustainability in the industry.

• Casa Grande, south of Phoenix, Arizona, is a fast-growing community in a fragile natural environment. The Frito Lay processing plant demonstrates how economic growth and environmental protection can go hand in hand.
