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....
