No more styrofoam?

[dougo.livejournal.com]

Sometime in the past few months, at least three restaurants stopped using styrofoam containers for packaging takeout meals: Deli-icious, Golden Light, and Teriyaki House (in Powderhouse Square). I think this is a good thing; besides the non-recyclability, I've always had an aesthetic dislike of styrofoam. But it made me curious: is this just a coincidence, or is there some particular reason that three local places switched around the same time? Did an anti-styrofoam ordinance go into effect? Did some supplier stop carrying styrofoam containers? Did non-styrofoam containers get cheaper? Does anyone happen to know?
