Is this material compostable in my back yard bin?

We bought some fruit in one of these new cellulose containers. Does any one know if they will degrade in a backyard compost bin?

I wish I knew. I wouldn't put anything with "polymer" in my bin, but that's just me.

I wish I knew, too. I read the info on the Nature Works site, but nowhere (that I could see) did this say anything regarding "disposal options," other than the quotation above.
Hope someone can answer your question for sure.

You might want to contact the manufacturer and ask about it. Very interesting, thanks for sharing the information.

Cellulose -- if I remember biology 101 correctly, isn't that organic? It's the "polymer" that makes me think it's some kind of I-can't-believe-it's-not-butter kind of thing. Like maybe it would break down physically but not chemically. The answer we seek is whether it would eventually be harmful.

Interesting!

Update, it's still recognizable as a container but it looks very "melty".

For what it's worth...

Biopolymers are biodegradable, and some are also compostable

Some biopolymers are biodegradable: they are broken down into CO2 and water by microorganisms. In addition, some of these biodegradable biopolymers are compostable: they can be put into an industrial composting process and will break down by 90% within 6 months. Biopolymers that do this can be marked with a 'compostable' symbol, under European Standard EN 13432 (2000). Packaging marked with this symbol can be put into industrial composting processes and will break down within 6 months (or less). An example of a compostable polymer is PLA film under 20μm thick: films which are thicker than that do not qualify as compostable, even though they are biodegradable. A home composting logo may soon be established: this will enable consumers to dispose of packaging directly onto their own compost heap. The standards for such a home composting logo have not yet been developed.

I wonder then if I should or shouldn't put it in the yard waste recycle pickup. I do use this compost for growing tomatoes and herbs and I wouldn't want to have this in my food if it's not good for consumption.

Hard to say. I don't think I would, but I'd hate to discourage you from it.

They use those for dishes at the cafeteria at Longwood Gardens, then ask the patrons to throw them in the compost. I'd do it.
