Sure. If you're gasifying something at high energy and turning it into its molecular building blocks, you can then take out the impurities and then just recover the hydrocarbons and reform them back into plastics, and that's what you're trying to achieve.
It's not perfect today, but with the right incentives there will be innovation to get to the point where we will theoretically be able to handle all the plastics that we put on the market today.
