Niether matter or energy can be destroyed; only changed.

You can light farts on fire, as they usually/often contain methane, but that partly depends on your diet and gut microbiome. I have no idea if burning a fart changes or eliminates the smell though.

Warning/Disclaimer: Since this only works when you ignite the fart right by the source (the anus obviously), you run a risk of the flame going into your rectum and potentially causing serious call 911 level injuries, so I don’t recommend trying that at all.

Spray disinfectant in that general direction to limit the effects.

Use axe body spray to mask the smell and annoy people even harder
