Interesting. What happens to the leftover carbon & sulphur?

I wondered that myself. They said the carbon is in the form of CO2 and CO, so I
expect that that's just exhausted. Perhaps the sulphur is SO2 and also exhausted.
We can hope not, but, if so, it's no worse than what's exhausted when the fuel s
burned.
