Ironically, we used to literally do it with milk a generation or two ago. You'd get milk in glass bottles, drink it, leave it outside in the evening, bring in more milk in the morning in reused glass bottles, and the bill is in the mail. Today with expensive glass bottled milks, they sometimes still offer a few cents redemption if you return the empty bottles to the store.

It's expensive but it's doable. Or you could say that the plastic milk people have successfully externalised enough of their costs that they can charge less than a more efficient option. Somehow producer levies to cover waste disposal are uncommon and wildly unpopular (with producers).
