You can feed the azolla waste water from a fish farm for sure. But then what do you feed the fish? The nutrients always have to come from somewhere and they have to end up somewhere. If you’re simply dumping azolla in a mine somewhere as carbon storage that then turns into a huge waste of nitrogen, phosphorus and potassium. It’s a very nutrient dense plant.
Yes you’re effectively sucking out nitrogen and carbon directly from the atmosphere and turning it into a solid. Furthermore, if you squeeze out all the water you get extremely dense cakes. You can use the energy generated from the solar panels to mechanically squeeze the azolla, use the squeezed out water back into the system.
I think azolla has been floated (hah!) as a scalable way to quickly fix atmospheric carbon. Maybe fish aquaculture for nutrient restoration?

Happy cake day, and yes, both. Carbon sequestration and animal feed.
