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?

Here's a variety of views into the complex production processes at Santa's factory. Happy Holidays!
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
Thanks to 3D printing, some custom-made prosthetic limbs, and a Lego set, one lucky dog and a tortoise has learned new tricks.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
With Radio Shack on the ropes, let's take a memory trip through the highlights of Radio Shack products.
