<< burned eh?
i can just imagine the potheads standing outside trying to get a whiff of the smoke
i mean 3 tons!!~ lol >>
meh.. When you smoke pot, you're vaporizing THC at rel. low temp. When you burn synthetic garbage at inadequate temperature it could lead to production of dioxin, therefore incinerators are designed to burn at VERY high temperature.
In a high temp blast furnace, tons of hard earned pot, dog poop, McDonald's paper bag, tree etc +oxygen from air=basically lots of H2O and CO2.
