In recent months I've decided that even though the 2L bottles are probably cheaper on a per-ounce basis, my waste 2L bottles were contributing to the plastic problem. I've switched to buying 12 ounce cans, which I open and pour into a glass.
My last purchase of Kola was as boxed 12-packs (no plastic in the packaging, other than possibly in the can liner [2]). I save my cans, and will be taking them to a local salvage yard to be properly recycled.
My trash company supposedly has "single stream" recycling, but I doubt they find all the aluminum cans the waste stream.
In drafting this comment I found a Wired story about the engineering that goes into can production [2]. My cans probably have BPA liners -- "hmm". Maybe I'll buy some Kola nuts and make my own herbal beverage.
