Another Innocentive

Hey everyone! I hope the first quarter went all right (alright? I can never remember) with you.  Here's a new Innocentive challenge to munch on:

The goal is to develop an environmentally friendly grocery bag/transport method.  They're looking specifically for single use ones.  

Yes, there are existing solutions, but all of them can be improved.  For example, I'm pretty sure Whole Foods uses paper grocery bags instead of plastic.  However paper is not as strong as plastic, and when you make the paper thick enough to be as strong as plastic, it becomes a lot more expensive.

What do you guys think? Post ideas in the comments.
