And landfill if it’s lucky. For a long time US “recycled” plastics went to China where they were burned. When they had to clean up the air pollution for the Olympics they stopped doing this, so the plastic was just shipped somewhere else, Malaysia if I remember correctly. (There is an Netflix documentary about it)
A local landfill is dramatically better than shipping it on a giant freighter halfway around the world to be set on fire.
The best option seems to be to reject single use plastics as much as possible. Force companies to make changes if they want to make sales.
Knowing that this whole thing was a scam (which has been known for quite a while) should push governments to take action. Not only against a the plastics industry, but also to push companies to move way from single use plastics.
