I feel some misunderstanding. but, after you burned and separated gases, you have a bottle full of CO2 and you completely under the control of what do next with it, and how much to release, where to release, how to release. Target destination plant growing compartments. Whatever it is, if we consider that food for those people is grown on the base then release where it is grown.
Those places would be isolated, should have microbiological control and should be protected by other means to prevent any sort of mishap
