Got it. I didn't intend my original post to be color-specific. But if that's the case, then all the more reason to just bury plastics.
(Or burn 'em, I guess, but when you have potentially a whole host of mystery toxic chemicals hiding in them, is your typical scrubber going to catch all of 'em? I don't know the answer, but I'd be surprised if specialization wasn't required. Probably safer to bury.)
decaBDE will burn to CO2 and bromine. Bromine is highly chemically reactive and will easily be caught in a filter.
Most chemicals are like that, they are either non-reactive and safe, or reactive and dangerous but easily filtered. (The in between stuff is a bit harder.) Interestingly it's true for nuclear reactions: The highly radioactive stuff decays very fast and is not a problem, the really long lived stuff is barely radioactive. The worrisome stuff has medium length lives.
