    this isn’t even recapturing CO2. It’s grabbing plant/decomposable waste before it rots

    Does this not amount to the same thing? The plants capture the CO2 and store it in sugar, which is then buried instead of burning it for energy or letting it rot.

      I agree. The concept is simple, and it’s not perfect, but it isn’t dumb either. This is basically recreating how coal and oil got in the ground in the first place. Plants absorbed carbon from the air as they grew, then they got buried in a way that prevented them from decomposing and re-releasing it into the atmosphere. My main question here would be whether burying it only 10 feet under ground is really enough for long term storage. The other big elephant in the room with carbon capture is that it can be a convenient excuse for companies to avoid doing work towards actually decarbonizing their operations. If, as the article suggests, this is used primarily by industries like cement making that don’t currently have a way to become carbon neutral then it’s a good thing. If it’s just used as cynical green washing by companies who could be doing better, then it’s at best a wash, and arguably a net negative.
