Plastics: an info round-up

Here are some interesting articles on plastics. I've written before on how confusing plastics can be, how you can't mix them all together for recycling, and especially how confusing all the new and different types of plastics out there can be.

These two articles address the new types of plastics. It's good to learn a little (or a lot) about these plastics, as they aren't necessarily all they're touted to be.

This tray may look like many other
plastic trays, but it's actually made
from PLA-polylactic  acid.

This forum post does a good job of differentiating between the different types (see near bottom-Jerry Powell's response) and this article is about claims of biodegradability.
