Re: Degrades to what?

Thanks for your comments, Ivan. Biodegradable plastics biodegrade into CO2 and water, the ingredients that they started as. That's what biodegradable generally means. Here are some definitions from the SPI:

And here is a tutorial on biodegradable plastics:

Good question, Ivan. I would expect the breakdown wouldn't be quick enough for composting. 

As an aside, one of Ann's sources is from the Freedonia Group. Freedonia, as many readers may know, is the fictional country the Marx Brothers were from in Duck Soup.

Degrades to what?

I would like to know what the biodegradable plastics degrade into?  I assume the resulting end product of the degraded material is environmentally safe and not an issue.

Also are there times associated with the designation such that the material must degrade naturally within a given time in some normalized environmental condition?

Would I want any of these in my compost bin?
