Bravo! This is one of the best articles I've seen on green dining options. I love the recycled streetlight plates, think I'll see about getting some for myself. They seem good regular use plates.
I consult for Verterra, the leaf based plates we're honored you included here. I have to say that I've been often surprised at their durability as compared to other biodegradable plates, without depending on binders (glue) to keep their shape.
If anybody has questions about them, I'd be happy to answer, or find out for you.
Meanwhile, here's a Time magazine photo essay on how they go from palm leaf to (nearly) bulletproof plates.
