Why not make pvc bio-degradable so that it can rot away?
PVC is mainly used in medium or long-life applications, for which its ability to resist natural degradation is a significant advantage.

When used in packaging, PVC is often chosen for its barrier performance and hence any process that would progressively impair this resistance would be counterproductive

Bio-degradable plastics are presented as one of the possible solutions to the problem of litter. The main products causing the litter problem are plastic carrier bags and plastic drink bottles. Neither of these products is made of PVC anymore, and hence PVC packaging is not actually a significant contributor to the plastic litter problem.
