CO2 Technologies – About Us

CO2 Technologies is a research and marketing company specializing in extending the life of perishable products. Our products feature a patented process that releases carbon dioxide (CO₂) and water (H₂O) to prevent the growth of bacteria on fruits, vegetables, meat, seafood, deli items, and flowers, allowing them to stay fresher longer.

CO2 Technologies is headquartered in Urbandale, Iowa, with additional representatives throughout North America, South America, and Europe.


The patented CO2 Technologies system releases molecules of CO₂ and H₂O on a continuous basis to keep food and other products looking fresh for a longer period of time – well up to their sell-by date. Here’s the impact it has on perishables:

• When CO₂ hits the moisture on the surface of food products, it turns to carbonic acid. When the increased level of carbonic acid is enough to affect pH, all bacteria sensitive to higher acidic levels ceases to grow – ensuring freshness and preventing shrinkage.
• Rapidly expanding CO₂ cools as it expands. As moisture in our product’s reaction evaporates, heat is absorbed. The result is colder air temperatures, so perishable product cases can maintain their temperature with less energy.
• Oxygen and ethylene can shorten the life of persihables. The heavier CO₂ released from our products displaces the lighter oxygen and ethylene gases, forcing it away from the surface of perishable items such as fruits, vegetables, meat and flowers
