Somebody uses them... There are other problems. I worked for Sweetheart
Plastics in the '80s. They made a line of EPS disposable plates as well
as clamshell containers for McDonald's. They literally bought CFC's by
the railway tanker for the blowing agent.

I was long gone by the time the industry moved to HFC's. They were
better for ozone depletion but still had a high GWP. (global warming
potential). Now they're looking at hydrofluroolefins which have a very
short life in the atmosphere. They are more expensive of course.

Shipping was a problem that I don't believe was ever solved. Rather than
essentially moving air around the country, some way to create the foam
product at the point of use would be ideal.

Or just use reusable drinking glasses/travel mugs/et alia and forgo the disposables.
