I would think so. Here in the U.S. we punch wells down into the landfill and pump the contaminated air to filter and such. Some places use it to run generators. But just a flare would at least get rid of the contaminated air. I imagine there are residues that might not be so great, but nothing like the hydrogen sulphide. Although I’m not sure how affects the body. I know if it gets too high it can kill you quickly - I think it replaces the O2 in your lungs so you sufficate? On oil rigs they have the H2S alarm.
I work in h2s environments. That stuff is extremely nasty and can kill you right quick. Even a small dose if it knocks you down, can leave you with permanent damage.
Neurotoxic with paralysis of breathing, pulmonary edema as life threatening symptoms.
