What about corn based PLA cups? No petroleum products, and they will decompose. Much quicker in industrial facilities, but supposedly within a year even in a backyard composter.

In reply to Keith Tanner :
I checked last night and my father was pretty sure cans were closer to glass than plastic. I also remain his oddest child, I’m sure he means that in a good way.

Interesting, never heard of those. Seems cool!
Glass has to be washed, presumably with hot water and detergent.
...so it's possible less energy is expended with single use containers.
I was getting coffee at a gas station the other day and saw plastic stir sticks wrapped in....plastic. That was sort of a bummer.
I’m in the plastics industry and work with many plastic packaging suppliers. The PLA containers are interesting but the physical properties don’t yet match the EPS and PET used now for hot filling. Glass is heavy and expensive to transport plus less durable than plastic and decomposes slowly as well. Aluminum cans match the weight of many plastic containers but are also energy costly to make and while recyclable decompose slowly too. Coated paper fits many uses but decomposes slowly and isn’t transparent so consumers can’t see the product. How do you know if yer Mountain Dew is really nuclear green through a paper package?!?!?!
