I just joined this community out of curiosity. I have been contemplating getting and using a cup, and while I've done plenty of research I still cannot find something. One of my only standing concerns with using a cup is what happens to it after it's life is over. How would you dispose of it after the 10 years you use it? I understand that using 'sposies (which I don't, ew) over ten years would be substantially worse than just one cup in the landfill would, but having it rot in a landfill would take away some of the environmental soundness from it, at least for me.
Does anybody know what happens to them after their time has run out? What is your theory?
