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?

Take a look at the top 20 US undergraduate engineering programs. Then tell us -- did your school make the cut?
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
A Silicon Valley company has made the biggest splash yet in the high-performance end of the electric car market, announcing an EV that zips from 0 to 60 mph in 3.4 seconds and costs $529,000.
The biggest robot swarm to date is made of 1,000 Kilobots, which can follow simple rules to autonomously assemble into predetermined shapes. Hardware and software are open-source.
