I saw a youtube video about how Japan burns materials that can’t easily be recycled to produce energy and captures the CO2 produced from the process. The CO2 is then sold to some local factories to produce various things like fire extinguishers, and some algae farms (I googled this and algae is used to produce food and oil).
I googled that at sea level, CO2 in the atmosphere is at 350 PPM, but certain plants thrive at 1500 PPM.
It got me thinking – why can’t we pump CO2 into indoor farms, plantations or forests to sequester more carbon?
Would that even work? Is the carbon just released into the air again once the plants are eaten or broken down?

I can think of one really effective carbon storing technology being developed right now with lots of promise. HempLime construction uses hemp hurd and hydrated lime to make affordable concrete-like building materials. Hemp itself can capture many times the CO2 of trees per acre, and by storing it in structures, we can safely lock the CO2 away while we develop even more efficient carbon capture technologies. Perhaps carbon capture credits could even be used to lower the cost of the construction, resulting in an affordable housing boom.
