A few of my local coffee and food joints have begun using biodegradable and compost-friendly corn-based containers. That’s about as much as I know—and they’re obviously priced low enough to be used by independent coffee houses and restaurants. Does anybody know drawbacks to this material? Seems like a decent idea to me. Less styrofoam and I’m told, with the cups at least, that they break down in compost in 45 days!
