Plastic waste should be burned for heat and/or electricity in an incinerator. Every other usage/disposal method seems like a waste to me. Instead of burning fossil fuels directly, we get much more value from them if we first turn it into some plastic product, and only then burn it. And as long as we keep burning fossil fuels for heat and power, let's not wate out attention on recycling (downcycling actually) plastics as we can much better burn the old and make fresh new plastic from the fossil fuels we didn't have to burn because of that.
When we are not relying on fossil fuels anymore for heat and power (which is hopefully sooner than later), only then we need to start looking into plastic recycling
