Ive noticed that too. Its a bit odd given that the firework makers seemed
to have gone to some lengths to make the rest of the fireworks out of
biodegradable materials. Many of the parts that look like plastic (rocket
nose cones and launcher tubes) seem to be made of that corn starch based
plastic and disintegrate pretty quickly.

The motors however all seem to be a translucent rigid hard plastic tubes
that dont *look* biodegradable. I could be wrong though.

Probably less susceptible to damp and hence to the firework that doesn't
appear to be going off, until somebody approaches it to check.
