Yup. The Japanese developed a contraption to process all plastics including the disposition of toxic gasses that may form when pvc is processed. Nice energy carrier and when I calculated the business case back in 2012, it was quite profitable. Of course, .gov regulation resists such niceties .... especially when localized and would very much offer a new stream of local .gov revenue.  It cleans up the landfill quite nicely, and if you do it right, no more plastics in rivers.
