The design of this cup is to have it flatten and packed it in a container (saucer) that is less than an inch thick. This would be then be stored into any customer bags thus avoiding the bulging effect unlike a normal cup or mug.
With a filled cup of coffee, material like heat resistant Polypropylene should be able to hold the coffee with tight fittings between the body and the saucer thus eliminating leakages. In order to better secure the cup while on the move, one just needs to place their middle/ring or little finger at the bottom of the saucer as a precaution.
The shape of the Lid is curve outward at both ends and fits into the body to conform to the curve making it easier to drink. Even when drinking without the lid, the PP material should be able to bend when touching the lip.
Another advantage of having a saucer could be that the open area would be large enough for cookies or small muffins (food that uses hands) thus reducing the use of plates
Even after drinking with only drops of coffee residues left, the consumer should know that it is safe to pack it in without any wiping off as the internal design of saucer will hold the residues and not letting it trickle out.
What about no time to wash the cup and it was left with coffee stains for a day or 2? One suggestion is to get staff of the coffee outlet to wash thus doing a service to save a tree while the customer would appreciate their kindness for a clean and sanitized cup.
Lastly and most important is to address the concern of beta cup, through the use my flat coffee cup, consumer would see the benefits of using it everyday and thus reducing wastage of the disposable cup and trees.

So sorry for the draft, anyway my main focus is to make it slim and neat package.
Yeah, staff may find it a hassle to wash for every individual customer. Washing Cup station is a good idea provided that it has a steaming function incorporated as that will eliminate using dish detergents.

May I also suggest that the place of origin (country/city) and a cultural pattern be embossed on the cup so that travellers would be able use on any Starbucks outlet in any cities. Starbuck would honour them by giving a small discount as a token of appreciation for saving a tree.
I believe that would certainly bring out the identity of the cup and generate a good rapport between Starbuck and the customers.

The precision-molded cup can be used everyday since it is make of PP and the drinkers just need to fold them into the saucer with the cover (red) in between them. The size should not be bigger than a PSP, making it handy, compact and self-contained.
I believe one of the reasons that drinker do not want to bring cup to any coffee outlet is the cumbersome shape and size. Which leads me onto tackling the SPACE issue. I hope just simply by changing the shape/size & the way of storage, everyone would be carrying one in their bag everyday 24/7 without thinking as a hassle.
With this design plus a good incentive program, coffee drinker and the provider will see it as a win-win. Of course the effects ripple throughout and will definitely help reduce wastes which will leads back to the less trees being cut.
