It doesn’t seem to be based on petroleum, since they’re explicitly comparing it to petroleum-based plastics…

There also are other non-petroleum based plastics that dissolve in water. This part is not new. E.g. polyvinyl alcohol is used widely.

What’s new about this one is that it specifically needs salt to dissolve and they claim it’s otherwise relatively sturdy. So maybe it could be used instead of pet bottles for drinks?
