Of course there are many negative side effects that come from burning PVC as well as its leaching (dioxins and heavy metals), but why are PE, PP and PET considered more environmentally sustainable? Is is because they can be broken down in landfills over time, or that they are cleaner when recycled and retain thier quality through each cycle far better than PVC? Or have they just not been around long enough to be disliked? Any information that helps me better understand this, I would be very interested in.
Thanks
