Sprouts Farmers Market and Hillphoenix push sustainable alternative

The Produce News, July 8, 2014

Arizona-based Sprouts Farmers Market is entering the Southeast in a big way. With one of its first stores in the metro-Atlanta area, the healthy grocery store chain is bringing one of the first CO2-based, HFC-free supermarket refrigeration systems to a warm-weather market in North America. The transition to CO2 as a sustainable alternative for supermarket refrigeration is booming in cold climate markets, with roughly 2,000 transcritical CO2 systems operating worldwide in cold weather cities. Until now, the southernmost Hillphoenix Advansor transcritical CO2 booster system in North America was located in Chicago.

Sprouts’ new store opens on July 18 in Dunwoody, GA, and will run on an Advansor transcritical booster system that entirely eliminates the use of hydro- fluorocarbons, which was for decades the refrigerant of choice in the supermarket industry. HFCs are damaging to the earth’s protective ozone layer and contribute to global warming. One pound of leaked HFC refrigerant can cause more global warming than 2,000-4,000 pounds of carbon dioxide. Increasingly, food retailers are moving toward more sustainable natural refrigerants including CO2, glycol and ammonia.
