The shift will be back towards reusables. Coke was once served in glass bottles - but centralized for increased profit due to invention — plastic was cheaper than glass to produce and transport.
Now, if the consumer provides their reusable, a company like Coke only needs to transport concentrate, which is far lighter than shipping a bottle of mostly water. That will also decrease the cost of the beverage to the end consumer. That’s a win - win for the planet (no packaging) and the price of the beverage (saves consumers money).
