The big issue when it comes to the new recycling technologies that I've been alluding to—and just as an introduction to chemical recycling—there are basically two predominant technologies. One is gasification and another is pyrolysis. The advantage of these technologies is that they can take basically all plastic, including styrofoam, coloured plastic and multi-laminate. There are no emissions associated with them. It's high heat in a zero-oxygen environment. What you get out of the back end, depending on the technology, is a rough grade diesel methanol or ethanol. That can then be turned back into plastic.
