Nah, the vast majority is trash to begin with or ends up as trash. Only a fraction ends up recycled.
Plastic bags don’t go in the recycling, they go in the trash bin.
It's not a matter of any one thing, the vast majority of "recycling" is trash to begin with, or ends as trash without being recycled.
That’s the goal. You want them to end up as trash. It’s not cost effective to recycle it, and if it were, that would lower costs and create more pollution.
