Single-use plastics aren't going away, even the "wokest" corporations use them for packaging. The problem is that in most countries and most households, they end up in residual waste where they're burned rather than recycled. Not even in modern, environmentally-conscious, high tax countries like Austria the garbage processing has been modernized to the point where plastics are separated and recycled from collected residual waste. This is what needs to be done (would be a good issue to regulate with EU law, as opposed to many others).
