A scrubber for controlling carbon dioxide levels in a shipping container containing respiring produce is disclosed. The scrubber is relatively small, utilizes a gas-selective membrane having a CO2/O2 selectivity ratio greater than 1:1, and fits inside the shipping container (such as a sea van container). In contrast to current methods of controlling CO2 levels in shipping containers, such as the use of hydrated lime, the scrubbers of the present invention are efficient, relatively inexpensive, do not take up shipping space within the container, and do not present handling or disposal issues. A method for controlling the carbon dioxide levels inside a shipping container containing respiring produce, utilizing the carbon dioxide scrubbers defined, is also disclosed. |
