A closed-loop ecosystem for life support works best by
being built around the monkey it supports.

If you burn organics, or exhale CO2, you could fixate some
or most of it by a photobioreactor just few 100 l big. Possibly
producing food as a result (spirulina and chlorella might be
not suitable as a sole food, but it's more than ok as a supplement).

Actually, if civilisation is to collapse, algaculture for food
could become rather important.
