In order to limit the use of plastics and paper involved in the "additions" stage to making your perfect cup of coffee, you could eliminate them with Eco-spheres. The concept is that of bath bubbles that dissolve in the tub, or laundry detergent packaging simply thrown in the washer that is widely popular in homes already.
By creating spheres of pre-mixed sugar and creamer balls to drop into your coffee  in Starbucks establishments, or on the go, you would eliminate the packaging of sugar, and save the plastics from creamers while creating a QUICK on the go method of flavoring your coffee.
Future versions can be flavored as well, such as mocha or almond, etc.
