Is chemical recycling the solution to plastic waste?

The issue of plastic waste is not going anywhere. In fact, globally, we continue to generate more of it. In the EU, plastic packaging waste alone makes up about 16 million tons a year - and less than half of that is recycled. But across Europe, new recycling plants have been popping up, promising to recycle hundreds of thousands of tons of the particularly-hard-to-recycle stuff using a technology called chemical - or "advanced" - recycling. Deutsche Welle, DW's, investigative environmental journalists Dan Ashby and Lucy Taylor look into the idea.
