While restaurateurs like the appearance of being “green” and “sustainable,” they aren’t really going to sort out all the paper straws used in their restaurant and try to find a composting facility that will take paper somewhere in the state of Arizona.
It’s just more promotional hype to tout that “we now provide compostable paper straws” without actually composting them. But then the truth is in the semantics: Yes, paper straws are compostable, technically. But they are not composted. That’s a major difference!
