Yes, and I admit the mention of bin bags might have been an unintentional red herring. I was just intending to point out that even in a "first world" country with supposedly good waste management, lots of plastic gets into the sea. Better not to have the single-use plastic in the first place. Bin liners can be made from things like starch. Those are generally for compostable waste, but I don't believe for a moment that companies wouldn't come up with something suitable pretty rapidly if there was money to be made.
