If plastic items (bags containing polishing waste, for example) are incinerated, they should be monitored closely. The bulk of plastic items don't burn well, turning to oil instead when heated.

If the ICs are not fully pyrolysed, you will see funky flames dancing above the material, smoke and you will strongly smell burning plastic. Incineration is the "harder" part because the pyrolysed material does not burn very well. It's like the comparison between hard coal and charcoal.
Huh, I've never actually heard of "food grade" H 2 O 2, I'll have to look for some today!
