Stack it up
Goal: The paper cups are lightweight, simple, and convenient, but they are thrown away after using once. However, the mugs can be used several times but it is discomfort that they need to be washed at every use. (Of course, washing is concern with pollution issues.)
The goal of my idea merges lightweight and convenient of the paper cups and multi-usability of mugs. It also improves inconvenience of washing effort.
Hot it works: The proposed cup is stacking of waterproof thin paper cups and it has its own sleeve. Stacked cups are looks like parchment paper for muffin. After enjoying coffee, you can rip off inner thin paper. This paper is made of environmentally friendly material because it is biodegradable. And the rest cups put the lid to keep clear.

Won't the paper liner be wet when you take it out and stick to the inside of the cup?
The cup design is very innovative
