... And what happens with the other chemicals and elements, mainly the carbon? Does it spit out graphite dust or something, or does it just spits out the good ol carbon dioxide?

The paper refers to the by products as “value added” and lists by products : “The major oxidation products detected after 22 h were formate and acetate (from pretreated cellulose), as well as glycolaldehyde (GAld) dimer and glycolate (from pretreated PET), respectively“

Later mentioning no detectable CO2 was produced when they analyzed it.

So at least it doesn’t seem to be the worst thing considering we burn a lot of plastics and waste today.
