One technological solution could be a "Package ID":

Imagine if every can, bottle, box, bag, utensil,.. contained a clearly legible identifier, that was machine readable (QR code?), that linked back to the manufacturer.

Then all these wasteful packages could be scanned and sorted using vision systems, and sent back to the originating manufacturer for disposal.

By making the producers responsible for cleanup it will surely change their balance sheet, and they will be forced to change. Or go bankrupt. Because their current business model is not viable when the costs of their environmental impact are considered.
