Final solution:
My solution to the disposable pop bottle is a system of bottle and machine that sells the Drink separately from the bottle. The vending machine has an option to buy either a full bottle of the desired product or refill a bottle that has already been purchased. Through price structure it is advantageous for the consumer to buy a bottle and use it multiple times rather than buy once and throw away.
The bottles through their design have a non-deposable aesthetic, however, they use the exact same amount of resources to manufacture as existing disposable ones. The labels are printed on the plastic to further extenuate the non-disposable aesthetic.
Eventually these bottles will probably be thrown away, however, if the user refills their bottle only a single time then there is one less pop bottle in a land fill. Chances are they would refill it more than once increasing the benefit each time. Hopefully it will never be thrown away.
Th insides of the actual machine will be like a hybrid of a soda fountain and a soda bottle machine.
