Some of the new ones I’ve seen are lined with a film made from sugarcane. They have the advantage of being completely organic in nature - you can throw them in FoGo. Unlike the plastic lined cups, I think they may have some sort of limited lifespan before they start to dissolve.
I always take my own cup, so I haven’t looked deeply into how long they last.
I think they mean paper coffee cups - they’re usually lined with plastic to make them waterproof.
