According to this, burning even so much as paper can be bad for your health, as well as the environments. In fact, as the link mentions several times, it is even illegal to burn or bury your household waste in Minnesota, with many other places globally adopting the same kind of policy.
So don’t do this to your trash:
Though a question I would like to raise in response to the article, is “Is there anything that can be done to destroy non-recyclable waste that doesn’t pose a threat to ours or the environments health?” Because as far as I know, burning it was the only way to actually eliminate it aside from letting it decompose on its own, but that too has some harmful repercussions on the environment. Well according to this, the only way to safely dispose of this sort of trash is in a sanitary landfill. I don’t like landfills. Just the idea to me sounds like it’s just an “out of sight out of mind” technique. But if that’s the only way to dispose of it safely, than so be it.
