Are you seeing returnable Coke bottles at your supermercado? I just saw a big Coke truck outside of one, with stacks of empty 2-L bottles in crates. Never having seen this before, I wondered when Coke had become involved in recycling.
Inside the store there was a display announcing their new returnable 2-L bottles. Seems like a good idea, in a country that consumes so much Coke.
