I definitely remember this, in the 90s. And it was around the same time that fast food restaurants (well, McDonald's at least) switched from styrofoam burger clamshells to the paper type. That was driven by environmentalists who didn't like landfills accumulating. There was also some ozone layer concerns I think? So paper was the better choice for the burger, yet plastic was the better choice for your groceries. I also remember Vons introduced photodegradable bags.(!) They were supposed to alleviate the litter concerns, while also allowing you to save a tree I think? I'm trying to find something online to back this up, but I remember the novelty of it when they first introduced it.
