It is cheaper and has a lower carbon footprint, but it works best on clean, single-type plastics.Chemical recycling breaks plastic down into its molecular building blocks (monomers, oils, or gases) so it can be rebuilt into new plastic. It can handle mixed, dirty, and multilayer waste, but it is more energy-intensive and still scaling up.... |
