Captured from industrial processes. Any big plants that burn a lot of fuel are great sources of high concentration CO2 for recovery and reuse. Natural gas reforming to make hydrogen, common in fertiliser plants also produces a lot of CO2. You'd have to look at their actual supplier to see where it comes from specifically, but it's always going to be recovered from some place that would otherwise be dumping it to the atmosphere. You'd never burn fuel just for the CO2, would make no economic sense.
Nice. I think it is only missing one thing: where does the CO2 come from?
