Exterior grade products are typically glued with
phenol-formaldehyde resins,
meaning that combustion products involve some really nasty chemicals.
Probably no worse chemicals than the wood itself. I'd burn it.
Here's a guy without a clue.

Not clueless. I'm a retired chemist. If wood is typically bound with
phenol resins, there is no harm in burning and combustion products are
no worse than burning pure wood. If it contains preservatives such as
arsenicals or chlorinated compounds or flame retardants of a similar
nature, it is best land filled.
OP and some respondents are not addressing issue.

So you see no problem with the _amount_ of binder? There isn't much
in natural wood, there is a whole lot in chipboard or any other
"manufactured" sheet goods.
I don't think that's at all what Frank said or intended -- the point is
what the chemistry is and what are the _actual_ combustion byproducts
produced rather than simply knee-jerk reaction of "bad".

If you look at wood chemistry:http://en.wikipedia.org/wiki/Lignin
and compare to phenolic resin:http://en.wikipedia.org/wiki/Phenol_formaldehyde_resin
You see a lot of similarity. Both when completely burned give carbon
dioxide and water. That's why I say the composite should be as safe to
burn as wood.

Assuming (and you are incorrect, it does give off other vapors) it
only gives off water vapor and CO2 you must not care about the green
house effect. Both affect it.
Burning wood _in the long run_ (pay attention to that) is carbon/water
vapor neutral. If not burned it puts out the same amount when it
decays. So what is different about particle board? The great excess
amount of the binders which is not carbon neutral.
