It's possible they're reusing the bottles instead of melting them down. That's what was done a long time ago, and isn't an option with plastic or metal cans. I can see how shipping could be more especially if it needs a cardboard case. Perhaps shipping would be negligible if we had more localized production and less long distance shipping. Rail shipping would likely have a negligible shipping cost difference. Even something like increasing the use of concentrated syrups and fresh made sodas could be a benefit for packing reduction and shipping costs.
