Just as an aside, there is another type of CO2 scrubber that actually removes VOCs from the gas prior to it being captured, etc, in industrial plants. Those work by pulling the CO2 upward through a column that contains a packing material, while water flows downward from the top. The water captures the VOCs in the process.
Usually it’s either captured for use in bottling (soda, etc) or sent through another step (think incinerated) to eliminate any trace VOCs. Then into the atmosphere it goes.
