I misread that as "combustible" and had a very different reaction than the rest of you, I suspect. Anyway. A few years ago a good coffeeshop near me tried a new brand of some VERY compostable cups. They were so compostable, in fact, that they would often degrade to the point of failure BEFORE I FINISHED MY COFFEE. Double- or triple-cupping would prevent this, but presumably that also undoes whatever other benefits were accruing, so they switched back.
