That is a very interesting thought since so far I believed that paper cups could fully be recycled, but I was wrong. going back to the old-school method where we only used reusable mug will need a radical change in our behaviour, at least now in the fast pace world, that would be a little bit inconvenience.
Sending some !LUV to you for the thought about it, and also for the lovely coffee cups shots. Sending some !PIZZA also to enjoy with the hot coffee.
Maybe !DHEDGE as another additional. : )
