I sit in a hot office and think about this. I am not sure where to ask. I am genuinely curious. I have seen a breakdown of building solar panels to power the earth 2x over in order to recapture carbon equal to the rate it is being produced, but then areas of the earth that were reflective are now absorbtive of heat…
I find out about biochar recently, pyrolize anything(usually woody matter) and you can use it as an amendment to soil as it’s high surface area holds water, nutrients and is a “hotel” for fungi and bacteria. It can also be used to absorb fertilizer runoff into rivers. You don’t necessarily have to dump it into a mine. Because it’s stable carbon it stays for 100s to 1000s years. Check out Terra pretta.
I think it’s best if done locally. I just dig a cone pit and throw it in my compost.
throw it in pig shit = long term fertilizer Add it to cattle feed and reduce methane farts
I’ve run across the term biochar a few times recently, but didn’t think anything of it. Thanks for prompting me to look into it seriously!
