My goal is to convert human waste into (less disgusting and more useful) plant mass while decreasing CO2 (for the sake of it) and I want to find seriously the most proper plant for that (I would think is kind of an invasive plant due to its robustness and quick growth).
I've delved into invasive plants, thought to use Kudzu. But it turned out that Kudzu actually contributes to global warming. I'm no plant expert, so I hope someone can guide me what plants should I look at.
Would C4 or C3 plants be a solution?
The climate of interest is humid continental, but it will be indoors, so most climate conditions could be imitated
