So, for what it’s worth… styrene/polystyrene is a byproduct of the production of gasoline from crude oil. You can either make things out of it, like cups and insulation, or burn it off at the top of the cracking tower, but if you’re going to produce gasoline, you’re going to get styrene. If you are going to drive cars and have electricity produced from oil, then your only two choices are breathe the styrene, or bury it. Neither alternative counts as good in my opinion.
