Well, there are several issues here that are only loosely connected:

o The feedstock that a plastic (or other container) comes
from. Oil, coal, starch, cellulose.....

o The extent and mechanisms by which it is "biodegradable,"
"compostable," etc. (are there any standards for the use of these
terms on labels?)

o How it fits into existing "recycling" programs and channels.

I'm certainly not a polymer chemist, but I think it is likely that
any material that can be polymerized can be
depolymerized. Traditionally people in the plastics industry devoted
themselves to making materials durable--resistant to sunlight, heat,
mechanical strain, etc. Now we are sort of saying we want some of
our plastics to last just long enough to do the job, them "poof!" We
are asking these materials to be pretty smart and socially responsible....
